!arc command

This command changes attributes of highlighted arc instances.
The format is:
        -arc [not] fixed-angle | rigid | temp-rigid | slide
        -arc [not] directional | negated | ends-extend |
                   skip-head | skip-tail
        -arc toggle fixed-angle | rigid | slide
        -arc toggle directional | negated | ends-extend |
                    skip-head | skip-tail
        -arc name NETNAME
        -arc not name
        -arc [not] center | curve
        -arc reverse
        -arc shorten
        -arc constraint CONSTRAINT [add]
        -arc not constraint

"fixed-angle", "not fixed-angle", "rigid", "not rigid",
"temp-rigid", "not temp-rigid", "slide" and "not slide" all
affect constraints on the highlighted arcs.

"directional", "not directional", "negated", "not negated",
"ends-extend" and "not ends-extend" all affect properties on the
highlighted arcs.

"skip-head" and "not skip-head" changes the ends-extend, and
directional property of the highlighted arcs.

"skip-tail" and "not skip-tail" changes the ends-extend, and
negated property of the highlighted arcs.

"name NETNAME" and "not name" sets or deletes the network name of
the highlighted arc.  NETNAME is an identifier stored with the
arc and linked to other arcs on the same electrical network.

"center" and "not center" sets the center of a circle that will
be used to draw the arc.  The cursor location will be adjusted so
that it is equidistant from the arc ends.  The "not center"
option removes the curvature so that the arc is straight.  This
option is used in circular geometry only.

"curve" also sets arc curvature, but in this case, the arc is set
so that its curve passes through the cursor.

"reverse" switches the two ends of the arc when they are
distinguished by the directional, negated, center, or curve
properties.

"shorten" reduces the selected arcs to their minimal length
by sliding them in their ports to the edge that is closest to
their center.

"constraint" sets or removes constraints for the nonstandard
solvers.  The add clause adds rather than replacing constraints.

To specify the arcs to be modified, use "find".
To set default characteristics for new arcs, use "defarc".
The arc constraints are used by the change commands: "move",
"rotate", "size" and "mirror".
For more information on named networks, see "help network".
For more information on standard arc constraints, see "help
laycon".
For more information on arc properties, see "help properties".
For control of nonstandard constraint systems, use "constraint".

!array command

This command replicates the currently highlighted objects.  The
format is:
        -array XSIZE[f][s] [YSIZE[f][s] [XOVERLAP [YOVERLAP
                                         [no-names] [diagonal]]]]
        -array file FILENAME

where XSIZE and YSIZE specify the size of the array and XOVERLAP
and YOVERLAP are the amount of overlap along the axes (negative
values cause the objects to be separated).  The default
value of YSIZE is 1 and the default values of XOVERLAP and
YOVERLAP are 0.  If either XSIZE or YSIZE ends with the letter
"f", then the array flips in that dimension so that every other
row or column is mirrored.  If they end with the letter "s", then
the array staggers alternate rows and/or columns.  The elements
of the array are given local names constructed from the indices
of the array.  This name can be accessed as the variable
"$~.node_name" on nodes and "$~.arc_name" on arcs, which
is useful in macros.  If the "no-names" option is specified at
the end, the array elements are not given local names.
If the "diagonal" option is specified at the end, the array
is linear, but both overlap distances are used.
If there are exports, they are arrayed only if the
"defnode * copy-ports" command has been issued.

The "file" option causes the named file to be read and used in
placement.  This file has commands to read cell libraries, place
the cells, and even route them to core facets.  Thus, it is really
a pad-frame generator facility.

For example, the command "array 4f 5" will create 4 columns of 5
objects and the second and fourth columns will be mirrored
vertically.

For more information about local names see "arc" and "node".
For more information about macros, see "macbegin" and "macend".
For more information about variable names, see "var".

!bind command

This command controls the bindings of commands to keys, buttons,
menu entries, and popup menus.  It also controls bind echoing.
The format is:
        -bind set button BUTTON COMMAND
        -bind set key KEY COMMAND
        -bind set popup NAME [message TEXT] ENTRY COMMAND
        -bind set input-popup NAME [message TEXT] ENTRY COMMAND
        -bind set menu [glyph NODE]
                       [message TEXT [textsize SIZE]]
                       [background COL] ROW[w] COLUMN[w] COMMAND
        -bind get LETTER button BUTTON
        -bind get LETTER key KEY
        -bind get LETTER popup NAME ENTRY
        -bind get LETTER menu ROW COLUMN
        -bind verbose | no-verbose

"set" causes a binding to change.  "set button" requires a button
name to be specified. (BUTTON can be "left", "middle", or "right"
on a three-button mouse, or simply "button" on a one-button mouse.
On those systems where buttons are sensitive to a double-click,
shift key, control key, option key, or meta key, prepend the
letters "d", "s", "c", "o", or "m".  For example, "mleft" is the
left button with the meta key held and "scmiddle" is the middle
button with shift and control held down.

"set key" requires a key name to be specified (KEY must be a
single letter).

"set popup" and "set input-popup" require a popup menu name
(NAME) and the entry within that menu (ENTRY).  The "input-popup"
option allows users to type additional parameters to the command
inside the menu.

"set menu" requires a menu co-ordinate position to be specified
(ROW is a row number where the bottom row is 0 and COLUMN is a
column number where the leftmost column is 0).  If the optional
"w" is placed after the column or row number, it forces the
meaning of row and column to be reversed whenever the column
extent is narrower than the row extent (i.e. it forces the first
number to be the "length" and the second number to be the
"width").

The "glyph" option of "set menu" causes NODE prototype to be
displayed in the menu to correspond with the binding.  The
"message" option of "set menu", "set popup" and "set input-popup"
causes TEXT to appear in the menu entry.  If the "message" option
is used with the "glyph" option ("set menu" only) then the TEXT
is used as an additional variable attribute on the NODE, and has
the form "ATT.VALUE" where VALUE becomes the string value of
attribute ATT.  The "textsize" option allows the message size to
be specified.  The "background" option of "set menu" causes the
named COL to be used to highlight the menu entry.

In all cases of binding, the COMMAND can be any other command,
with parameters, that will be executed when the button, key,
menu, or popup entry is selected.  If the command is "-" then the
binding will be removed.

"get" obtains the current binding for either key KEY, button
BUTTON, popup entry ENTRY in menu NAME, or fixed menu row
ROW and column COLUMN.  The binding is placed in the command
interpreter variable LETTER.

"verbose" and "no-verbose" set the display of bound commands
before they are executed.  The default is to display commands
(verbose).

Examples:
"bind set menu 1 0 quit" will cause a hit on the upper-left menu
   entry to quit the program.
"bind set key W window split" will cause the W key to split the
   current window.
"bind set button middle show history" will cause the middle mouse
   button to print the recent changes.
"bind set popup harry message "Huh?" 0 help" will cause the first
   entry of popup menu "harry" to show the message "Huh?" and
   execute the help command.

!color command

This command manipulates the color map that is used for all
display.  The format is:
        -color entry INDEX [VALUE]
        -color pattern LAYER [VALUE]
        -color mix
        -color highlight LAYERS [PERCENTAGE]
        -color default
        -color black-background
        -color white-background
        -color read MAP-FILE
        -color write MAP-FILE

"entry" allows display or modification of a single entry in the
color map.  INDEX is the particular entry and can be specified
either as a number from 0 to 255 or a combination of layer
letters.  If VALUE is not specified, the INDEX entry's current
value is printed.  If VALUE is given, that index is changed to
the value.  VALUE must be three numbers for red, green, and blue,
ranging from 0 (off) to 255 (on).

"pattern" allow display or modification of a single entry in the
pattern table.  LAYER is the particular layer letter to modify.
If VALUE is not specified, the LAYER entry's current value is
printed.  If VALUE is given, that layer is changed to the value.
This is up to eight numbers separated by slashes (/).  These
numbers form a 16x8 bit pattern for the layer (only the low 16
bits are used in each number).  If there is no number, but just a
slash, the previous value for that row is used.  If there are
less than eight numbers, the sequence is repeated until the 8
rows are filled.

"mix" allows the interactive selection of the 32 overlappable
colors from a mixing wheel.

"highlight" modifies the color map so that the overlappable
layers specified in LAYERS remain full color, and all others are
washed-out.  Thus, the specified layers are highlighted.  Only
overlappable layers may be specified.  The other layers are
reduced to 20% of their saturation (unless a specific PERCENTAGE
is given).

"default" loads the default color map for the current technology.

"black-background" loads a color map for the current technology
that has a black background.

"white-background" loads a color map for the current technology
that has a white background.

"read" reads the disk file MAP-FILE and loads the complete color
map in that file.  If the file MAP-FILE cannot be found, the file
MAP-FILE.map will be checked.

"write" writes the current color map to the disk file MAP-FILE.

Examples:
"color entry 33" will print the color of facet borders.
"color entry 64 0 0 255" will set the color of the grid to bright
   blue.
"color mix" will interactively mix the color map.
"color pattern c 0x5555/0xAAAA" will set the contact cut pattern
   to a checkerboard of dots.

For a list of color map entries, use "help map".
To see which layer letters are available, use "visiblelayers".
For the format of map files, use "help mapfile".

!commandfile command

This command reads and executes a disk file of commands.  The
format is:
        -commandfile FILENAME [verbose]

where FILENAME is the name of a disk file containing commands to
Electric.  If the file ends with the extension ".mac" then that
extension need not be specified.  If the optional "verbose"
appears after the file name, the commands will be printed before
they are executed.  Otherwise they will be executed silently and
normal command output will be suppressed.  In command files, any
lines that are blank or begin with a semicolon (;) are ignored.

To force output to the status terminal while inside a command
file use "echo".

!constraint command

This command manipulates the constraint solvers in Electric.  The
format is:
        -constraint use SOLVER
        -constraint tell SOLVER MESSAGE

use switches to constraint solver SOLVER.

"tell" sends MESSAGE to solver SOLVER.  In general, this option
is not undoable.

To see which constraint solvers exist, use "show solvers".
To see which messages apply to the linear-inequalities solver,
use "help linear".

!copyfacet command

This command copies one or more facets.  The format is:
        -copyfacet [FROMLIBRARY:]FROMFACET [[TOLIBRARY:]TOFACET]

where FROMFACET is the name of an existing facet in the current
library (or in the library named FROMLIBRARY if specified) and
TOFACET is the new facet name in the current library (or in the
library named TOLIBRARY if specified) that will be created with
a copy of the contents of FROMFACET.  If TOFACET is not specified,
it defaults to the same name as FROMFACET (which, when copying
within the same library, amounts to making a new version of a
facet).  When crossing libraries, all subfacets and associated
views are also copied.

If the keyword "quiet" is at the end, less information is
displayed.  If the keyword "move" is at the end, the facets are
deleted from the original library, and links to them are changed
to point to the new copies.

To make a skeleton version of a facet, copy it to the same name
with the view "{sk}", for example "copyfacet hardy hardy{sk}".

To make an iconic version of a facet, copy it to the same name
with the view "{ic}", for example "copyfacet mylogic{sch}
mylogic{ic}".  With skeletonization or iconization, the TOFACET
name can be omitted, for example "copyfacet hardy {ic}".

!create command

This command creates a node or arc.  The format is:
        -create [wait-for-down] [remain-highlighted]
        -create angle [ANGLE]
        -create join-angle [ANGLE]
        -create to X Y
        -create insert|breakpoint
        -create contents

The default form of the command creates either a node or an arc.
If the currently highlighted area does not contain two objects,
a node of the current node type is created at the current cursor
position.  Otherwise, an arc is created between the two
highlighted objects.  The current arc type is used as a default,
but if it cannot be run, any other arc type will be used.  If the
arc must bend to make the connection, intermediate pin nodes will
be created.  The nature of the bend and the particular ports to
use can be guided by the location of the cursor.

"wait-for-down" requires that the button be pushed before the
creation be done.  Thus, if this command is attached to a button,
it will require a second button hit to create.

"remain-highlighted" indicates that, after arc creation, the
originally highlighted nodes are to remain that way.

"angle" and "join-angle" specify that the wire should be run at
some increment of ANGLE degrees (where the default angle
increment for the arc is used if no ANGLE is provided).  When the
currently highlighted area contains two objects, an arc is run
between them at the desired angle increment.  When only one node
is highlighted, a wire is drawn from it to the cursor location.
This wire will then connect to the object under the cursor (with
the "join-angle" option) or to a newly created pin (with the
"angle" option or when there is nothing under the cursor).  These
options are useful for "drawing" wires.

"to" places a new node at the absolute location (X, Y).

"insert" specifies that a new node should be inserted in the
currently highlighted arc at a point close to the cursor.  The
current node prototype will be used and connected at the first
two ports that can take that arc.

"breakpoint" specifies that two new pin nodes connected by an arc
should be inserted in the currently highlighted arc at a point
close to the cursor.  The arc thus has a jog in it and one half
can be shifted away from the other.

"contents" indicates that even if the current facet has an
alternate icon view, its actual contents should be placed.

The granularity of the object placement can be set with "grid".
Default characteristics of newly created arcs and nodes are
   specified with "defarc" and "defnode".
To select the objects for arc creation, use "find" and
   "find more".
To set the default node or arc type, use "find" or "getproto".
To copy the currently highlighted objects, use "duplicate".

!debug command

This command is not for general consumption.  It prints debugging
information and patches the database.  The format is:
        -debug arena [CLUSTER]
        -debug check-database [verbose]
        -debug freeze-user-interface
        -debug internal-errors
        -debug namespace
        -debug rtree
        -debug remove-parameters
        -debug undo

"arena" prints the entire memory allocation arena or just the
part for cluster CLUSTER, if specified.

"check-database" examines and fixes internal lists (which should
already be correct).  If the keyword "verbose" is added, extra
information is printed during the check.

"freeze-user-interface" makes all macros and other user-interface
customizations be permanent parts of the database so that it can
be saved to disk.

"internal-errors" toggles the printing of internal database
errors (initially on).

"namespace" prints the variable names in the global namespace.

"rtree" prints the R-tree geometric data for the current facet.

"remove-parameters" removes all user-specified settings from
the database so that the library can be saved without overriding
these settings when read back in (useful for cell libraries).

"undo" shows a dialog with the change history.

!defarc command

This command manipulates the default arc creation environment.
The format is:
        -defarc PROTOTYPE | *
        -defarc PROTOTYPE [not] (fixed-angle | rigid | slide |
                directional | negated | ends-extend)
        -defarc * [not] (fixed-angle | rigid | slide |
                directional | negated | ends-extend)
        -defarc (PROTOTYPE | *) default
        -defarc PROTOTYPE width WIDTH
        -defarc PROTOTYPE angle ANGLE
        -defarc PROTOTYPE pin PINNODE

PROTOTYPE is an arc name from the current technology.  If "*" is
used, the command applies to all arc prototypes (not all of these
options can apply to all arc prototypes).  If only the PROTOTYPE
(or "*") is given, the default state is printed for that
prototype (or all prototypes).

"fixed-angle", "not fixed-angle", "rigid", "not rigid", "slide"
and "ot slide" all affect default constraints on the indicated
arc prototypes.

"directional", "not directional", "negated", "not negated",
"ends-extend" and "not ends-extend" all affect default properties
on the indicated arc prototypes.

"default" indicates that the creation style should revert to its
initial state.  When "*" is specified, defaults set on all arcs
will be removed and individual arc characteristics will prevail.

"width" sets the default width of the specified arcs ("*" cannot
be used here).  New arcs will be WIDTH wide.

"angle" sets the default angle increment of these arcs to ANGLE
degrees.  A value of 90 produces Manhattan arcs and a value of 0
allows any connection angle.

"pin" sets the default pin node to be used when creating the
specified arcs ("*" cannot be used here).  New arcs will be wired
with the PINNODE node.

Examples:
"defarc * rigid" will set all new arcs to be rigid.
"defarc metal not fixed-angle" will set new Metal arcs to be
   flexible in their angle.
"defarc * default" will set new arcs to their initial defaults.
"defarc diffusion width 5" will set the default width for new
   Diffusion arcs to 5.

To change the characteristics of existing arcs, use "arc".
For more information on arc constraints, use "help laycon".
For more information on arc properties, use "help properties".

!defnode command

This command  changes the default characteristics of newly
created nodes and affects node prototypes.  The format is:
        -defnode PRIMITIVE [size X Y]
        -defnode (FACET | *) [[not] expanded]
        -defnode * [placement [ANGLE]]
        -defnode FACET [not] alterable
        -defnode (FACET | *) [[not] instances-locked]
        -defnode * [not] locked-primitives
        -defnode * [not] centered-primitives
        -defnode * [not] check-dates
        -defnode * [not] copy-ports
        -defnode (FACET | *) [not] from-cell-library

The first argument is always a node prototype name: either a
PRIMITIVE rom the current technology, a FACET name from the
current library, or "*" which means that the command applies to
all node prototypes.  If nothing else is given, current defaults
for that prototype are listed.

"size" indicates that the default size of these newly created
primitives will be X by Y.

"expanded" indicates that the contents of facets will be visible
when created.  The negated form, not expanded indicates that the
contents of facets will not be visible when created but will be
drawn as boxes with the facet name inside.  If either option is
set for all facets ("*") then only those currently defined will
be affected.

"placement" indicates that all newly created node prototypes will
be oriented at ANGLE degrees.  If ANGLE is not specified, then it
will be 90 degrees more then the current placement angle.  If the
letter "t" follows the angle, then nodes are transposed after
being rotated.

"alterable" indicates that changes may be made to facet contents
(this is the default state).  "not alterable" locks all changes
to facet contents (this is useful when the facet is finished and
should only be viewed, not changed).

"instances-locked" indicates that no changes may be made to instances
(off by default).  "not instances-locked" locks all instances in
facets (this is useful when routing around already placed facets
that should not be further moved, deleted, created, or otherwise
altered).

"locked-primitives" indicates that changes may be made to
lockable primitives (this is the default state).
"not locked-primitives" locks all changes to primitives (this is
useful when working with array technologies that have lockable
primitives).

"centered-primitives" indicates that placement of new primitives
will be done by the node center.  "not centered-primitives" makes
new nodes be placed by their edge (this is the default).

"check-dates" indicates that the creation and revision dates of
subfacets will be checked and warnings will be issued if a
facet's revision date is earlier than some of its subfacets.

"copy-ports" indicates that subsequent commands which make copies
of nodes (duplicate, array, and yanknode) will also copy exports
on those nodes.

"from-cell-library" indicates that the named facets (or all
facets if "*" is used) are marked as part of a cell-library
(or not part of a cell-library).  Cell libraries are libraries
whose contents are unrelated and may be copied into other
libraries that contain hierarchies.  Facets marked as part of a
cell-library can be excluded from facet listings, making the
listings cleaner.

Many of these characteristics are used by the "create" command.
To change the orientation of existing nodes, use "rotate" or
   "mirror".
To change the size of existing nodes, use "size".
To change the expansion of existing nodes, use "node".

!duplicate command

This command copies the currently highlighted objects, exactly as
they are, to a new location specified by the cursor.  If there
are exports, they are duplicated only if the
"defnode * copy-ports" command has been issued.

To specify the objects to be copied, use "find".
The granularity of the new object placement can be set with
   "grid align".

!echo command

This command echoes its arguments back to the status terminal.
It is only intended for use in command files and macros that
wish to generate messages.  The format is:
        -echo MESSAGE

Where the MESSAGE will be printed.

To use command files, see "commandfile".
For more information about macros, see "macbegin" and "macend".

!editfacet command

This command changes the current facet that is being edited.
The format is:
        -editfacet [FACETNAME] [new-window] [non-redundant]

where FACETNAME is the name of a facet in the current library
that is to be edited.  If no facet with that name exists, one is
created.  The display then changes to show the new facet and it
is available for modification.  If no facetname is specified, the
currently highlighted facet is selected for editing.

The "new-window" option causes a new display window to be created
for the facet.

The "non-redundant" option prevents a new window from being
created if the desired facet is already being displayed.

To specify the facet to edit by default, use "find".
To rename a facet or cell, use"rename".
If you go into a facet in the current window you can pop back
   out to the current window with "outhier".

!erase command

This command erases the currently highlighted objects.  The
format is:
        -erase [pass-through]
        -erase geometry
        -erase (clean-up | clean-up-all)

If a node is erased, it and all connecting arcs are erased.  If
the erased node has an export, all arcs to that port in outside
instantiations of the current facet are erased.  If all arcs on
a pin are erased, the pin is also deleted.

The "pass-through" option causes the connecting arcs of an erased
node to be reconnected with a new arc.  This reconnection option
only works if the node has exactly two arcs of the same type
connected to it.

The "geometry" option causes everything in the selected area to
be erased.  Arcs that cross the selection boundary are cropped to
the boundary edge, thus erasing only the geometry in the selected
area.

The "clean-up" option causes all stranded pins to be removed,
oversized pins to be shrunk, extraneous arcs and pins to be
collapsed, and the facet to be made more "editable".  Zero-size
nodes are highlighted.

The "clean-up-all" option cleans-up all facets in the library.

To specify the nodes and arcs to be erased, use "find".

!find command

This command selects objects on the display closest to the
cursor.  The format is:
        -find [more] [port] [vertex] [extra-info] [exclusively]
              [within] [no-box] [special]
        -find area-move | area-size | area-define
        -find [port] [extra-info] [more] [still] [no-box]
              [special] [constrained]
              interactive | comp-interactive
        -find vertex within interactive
        -find constraint-angle ANGLE
        -find constraint-default [on | off]
        -find [extra-info] [port] [no-box] all [easy | hard]
        -find snap-mode (none | center | midpoint | endpoint |
              tangent | perpendicular | quadrant | intersection)
        -find (down-stack | up-stack)
        -find save NAME
        -find name NAME [extra-info]
        -find [more] [extra-info] [exclusively] arc ARCNAME
        -find [more] [extra-info] [exclusively]
              [vertex] node NODENAME
        -find [more] [extra-info] export PORTNAME
        -find object (TYPE ADDR | TYPEADDR)
        -find clear
        -find nonmanhattan
        -find set-easy-selection | set-hard-selection
        -find deselect-arcs

The default selects the closest node or arc to the cursor.  If
there is more than one object under the cursor, then successive
find commands will find all of them in sequence.  Therefore, if
you don't get the object you want, keep pressing the button.

"more" indicates that the currently highlighted objects should
remain highlighted and the newly selected object be added to the
highlight.  Not all commands can handle multiple highlighted
objects.  A special case of this option is when it is used with
the "interactive" option.  In this case, it indicates that
selection should cycle to the next object directly under the
cursor (if there is one) rather than sticking with the
highlighted object (which is the default way of doing interactive
highlighting).

"port" indicates that, in addition to selecting an object, the
closest port to the cursor should also be highlighted.  This only
works if a node is selected.

"vertex" indicates that, in addition to selecting an object, the
closest vertex to the cursor should also be highlighted.  This
is only valid if a node with an outline description is selected.

"extra-info" indicates that, in addition to highlighting the
object, additional information should be displayed (the arcs
connected to a node and the constraints on an arc).

"exclusively" indicates that only arcs of the current arc type or
nodes of the current node type should be selected.

"within" indicates that the find should take place in the same
object that is currently highlighted.  This is useful when
selecting another vertex on the ame node.

"no-box" indicates that no bounding box should be drawn around
the object that is selected.  The assumption is that some other
highlighting ("port" or "extra-info") will apply.

"special" indicates that special objects should be selected
(without this option, instance names and facet centers are not
selectable).  Also, other objects (facet instances, annotation
text) can be included in this category so that they are not
selectable unless "special" is used.

"area-move" sets the lower-left corner of an arbitrary
rectangular highlight to the current cursor location.

"area-size" stretches the upper-right corner of the arbitrary
rectangular highlight to the current cursor location.

"area-define" selects a complete rectangular highlight by first
waiting for a button push, then stretching from that point until
the button is released.

"interactive" implements a Macintosh-like find/move.  Any object
directly under the cursor will be selected.  If nothing is under
the cursor, a rectangular region will be obtained as long as the
cursor is down, and all objects in that region will be selected.
If the cursor moves after selection, the objects will be moved.
If a constraint angle is specified (with the "constraint-angle"
option) and constraining is requested (with the
"constraint-default" option) then object motion is constrained
to increments of that angle.  The use of the "constrained" option
toggles the application of constraints.  When the "interactive"
option is used with the "within" and "vertex" options, it selects 
and moves outline points in the current polygonally defined node.
The "more" option causes cycling of the direct hits under the
cursor, rather than sticking to the highlighted object, and does
not move objects. The "still" option causes objects to be found
only and not moved.

"comp-interactive" implements another part of the Macintosh-like
find/move by complementing the selection of what is under the
cursor.  The optional ANGLE constrains moves to increments of
that angle about the starting point.  The "stil" option causes
objects to be found only and not moved

"constraint-default" sets the default constraint that will be
applied to the "interactive" and "comp-interactive" options.
When on, these commands will constrain object motion to
certain angles.  When off, these commands will not constrain
object motion.

"constraint-angle" specifies the angle that object motion will
be forced into (in degrees about the starting point).

"all" indicates that all objects in the current facet should be
highlighted.  If "easy" or "hard" is specified, then only nodes
and arcs that are easy-to-select (or not easy-to-select) will be
highlighted.

"snap-mode" sets a snap-point selection mode for subsequent
"find" commands.  The "center" option selects the center of arcs
and circles; "midpoint" selects the midpoint of lines; "endpoint"
selects the end points on lines and arcs; "tangent" selects a
tangent point to arcs and circles (two snap points must exist in
order to determine proper tangents); "perpendicular" selects a
close point on lines, arcs, and circles; "quadrant" selects a
point on an axis on arcs and circles; and "intersection" selects
an intersection between two objects.

"down-stack" indicates that the current highlight selection
should be pushed onto a stack.  The highlighting is not changed
by this option.

"up-stack" indicates that the top entry of the highlight stack
should be popped off and highlighted.  The cursor position is
not relevant here.

"save" indicates that the current highlight selection should be
saved under the name NAME.  The highlighting is not changed by
this option.

"name" indicates that the highlight selection that was saved with
the name NAME should be retreived.  The cursor position is not
relevant here.

"arc" indicates that the arc (or network) named ARCNAME should be
highlighted.

"node" indicates that the node named NODENAME should be
highlighted.

"export" indicates that the node with the export named
PORTNAME should be highlighted.

"object" indicates that the object at address ADDR of type TYPE
should be highlighted.  If a single keyword is given, it has
both TYPE and ADDR as one (no separating space).

"clear" indicates that all highlighting should be removed.

"nonmanhattan" indicates that all nonmanhattan geometry should
be selected.

"set-easy-selection" and "set-hard-selection" cause the selected
nodes and arcs to be marked "easy to select" (or not "easy to
select").

"deselect-arcs" causes all selected arcs to be unhighlighted.

To name a node or arc, use the "node" or "arc" commands.
To set outline information on a node, use the "node trace" command.

!getproto command

This command selects a specified node or arc as
the current prototype for creation.  The format is:
        -getproto [node] [TECHNOLOGY:]NODE
        -getproto [arc] [TECHNOLOGY:]ARC
        -getproto next-proto | prev-proto | this-proto

"node" and" arc" are optional indicators of the type of object
being selected.  If not specified, the command will automatically
determine the intended object.

NODE is the name of the node prototype and it can be preceded by
a technology name TECHNOLOGY if it is not in the current
technology.  NODE can also be a complex node prototype from the
current library.

ARC is the name of the arc prototype and it can be preceded by a
technology name TECHNOLOGY if the arc prototype is not in the
current technology.

"next-proto" and "prev-proto" indicate that the next or previous
prototype in the list is to be selected.

"this-proto" indicates that the facet currently being edited
should be selected as the current node prototype.  This is useful
for picking up the facet in one window for creation in another
window.

The selected object is used by the "create" command.
Another way to select the current object is with the "find"
   command.

!grid command

This command controls the display of a grid on the screen and
the alignment of newly created objects to that grid.
The format is:
        -grid [size X [Y]]
        -grid alignment ALIGNMENT
        -grid edges ALIGNMENT

With no arguments, the command toggles the display of the grid.

"size" specifies that the grid should be displayed every X by
Y lambda units on the screen.  With one argument, the grid is
made X by X units in size.

"alignment" specifies that both coordinates of the cursor will be
snapped to the nearest ALIGNMENT lambda units when pointing to
the screen.

"edges" specifies that the edges of manhattan arcs will be
snapped to the nearest ALIGNMENT lambda units when adjustment
is allowed within the port areas.  This applies to the "create"
and "size" commands.  The value zero (the default) indicates
that no edge alignment is to be done.

!help command

This command displays help about any of the commands in the
program.  The format is:
        -help
        -help manual
        -help illustrate
        -help news
        -help pulldowns

Where the command with no arguments presents this dialog for
getting help on every command.

"manual" causes the HTML manual to be displayed in a browser.

"illustrate" causes the entire space of Electric commands to be
converted into a facet that can be viewed and edited.

"news" is a facility that prints the most recent news about
Electric, from a system-wide information file.

"pulldowns" dumps all pulldown menus to a disk file.

To get help on the single key commands, the commands in the
menus, or the commands on the buttons, use "bind" to see what
full command names they are bound to and use help on those
command names.

!if command

This command conditionally executes another command or macro.
The format is:
        -if TERM1 RELATION TERM2 COMMAND

where TERM1 and TERM2 are values that will be compared with the
RELATION and RELATION is one of ==, !=, >, >=, <, or <=.
If the relationship holds, then COMMAND will be executed.

!interpret command

This command invokes a language interpreter which provides a
high-level interface for Electric.  The format is:
        -interpret [lisp|tcl|java] [CODE]
        -interpret file (lisp|tcl|java) FILENAME

Where the first argument is an optional language subsystem
("lisp" is ELK LISP, "tcl" is the TCL language, "java" is JAVA).
If CODE is given, it is executed immediately.  Otherwise, an
interpretive session is begun.

If the first argument is "file", then the second argument is the
language name and the third is a disk file to be read into that
language interpreter.

When in the interpreter, you can enter code which will be
evaluated.  Special forms can be used to access the Electric
database.  You can exit from the interpreter and return to
Electric with a ^D.

The "var" command allows code to be attached to database objects.

!iterate command

This command repeats the previous command.  The format is:
        -iterate [COUNT | ARRAY-VARIABLE MACRO]

where COUNT is the number of times to repeat the last command.
If the count is not specified, it defaults to 1.

If two arguments are given, they are an ARRAY-VARIABLE and a
MACRO to run.  The macro is called once for each entry in the
array, and it is given two parameters: %1 is the type of the
entry and %2 is the address.

!killfacet command

This command deletes a facet from the current library.
The format is:
        -killfacet FACETNAME

where FACETNAME is the name of an existing facet in the current
library.  If there are any instantiations of the facet, the
command will fail and explain why.

To rename a facet or cell, use "rename".

!lambda command

This command changes the value of lambda: the size of a single
unit.  The ormat is:
        -lambda
        -lambda change-lib VALUE
        -lambda change-all-libs VALUE
        -lambda change-tech VALUE
        -lambda display-units (lambda | micron | inch |
                               centimeter | millimeter |
                               half-millimicron)
        -lambda internal-units (millimeter | half-millimicron)

The smallest unit is the half-millimicron (one two-thousandth of
a micron).  Lambda is the number of half-millimicron per design
unit.  Thus, if lambda is 2000 and a transistor has the size 2x2,
then that transistor is 4000x4000, or 2 microns square.  The
default command prints the values of lambda for all technologies
in use.

"change-lib" indicates that the entire library should be scaled so
that all objects remain the same size in lambda units.  All that
changes is their absolute size in microns, not their relative
size in lambda.  "change-all-libs" works on all current libraries.

"change-tech" indicates that the value of lambda is all that
should be changed.  Existing designs will not be scaled and so
will remain the same in microns but will change in the number
of lambda units.

The "display-units" option sets the way that distance will be
presented textually.  The default is "lambda" which causes all
numbers to be relative to the current lambda grid size.  With
other units, Electric will use appropriate letters after all
values (i.e. 12.3u for microns, 15" for inches).

The "internal-units" option sets the minimum database unit.
The default is half-millimicron, but for larger designs, other
values can be used to scale the database.

The new value of lambda, VALUE, applies only to the current
technology.

!library command

This command manipulates libraries of cells and facets.  The
format is:
        -library use LIBRARY
        -library new LIBRARY
        -library kill [LIBRARY]
        -library read FILE [binary | text | cif | lef | def |
                            gds | edif | sue | dxf] [make-current]
        -library write LIBRARY [binary | text | cif | gds |
                                edif | dxf | l | plot | hpgl |
                                eagle | pads | lef |
                                postscript | printed-postscript]
        -library purge
        -library save
        -library default-path PATH

"use" indicates that LIBRARY should become the current library.
If the name does not exist, a new library will be created with
that name.

"new" indicates that LIBRARY should be created, but not set to
the current library.

"kill" indicates that LIBRARY should be deleted.  The default is
to kill the current library.  You cannot delete the last library
because there must always be a current library.  If the library
to be killed has changed but not saved, you will be asked to
confirm that you really want to kill it.  This option is not
undoable.

"read" causes the specified disk file FILE to be read into a
library.  The additional format options "binary", "text", "cif"
(Caltech Intermediate Format), "lef" (Library Exchange Format),
"def" (Design Exchange Format), "gds" (Calma GDS II), "sue"
(Schematic User Environment), "edif" (Electronic Design
Interchange Format), and "dxf" (AutoCAD format) indicate the
style of the library file (the default is "binary").  The
additional option "make-current" causes this library to become
the current library after being read.  This option is not undoable.

"write" causes the specified library LIBRARY to be written to
disk.  The additional format options "binary", "text", "cif",
"gds", "eagle", "edif", "dxf", "l", "lef", "pads", "plot", "hpgl",
"postscript", "printed-postscript", and "skill" indicate the style
of the library file (the default is "binary").  This option is not
undoable.

"purge" cleans the current library by deleting all facets that
are have newer versions and are no longer in use.

"save" requests all libraries that have been changed to be
written in binary format.  This option is not undoable.

"default-path" sets the default location of system library
files.

To see a list of libraries, use "show libraries".
To rename a library, use "rename".

!macbegin command

This command marks the start of a set of commands that are to be
grouped together into a macro.  The format is:
        -macbegin NAME [verbose | no-execute]

where NAME is the name of the macro.  The optional "verbose"
switch indicates that the macro commands are to be echoed when
executed (by default they are not echoed when executed).  The
switch "no-execute" indicates that the macro is not to be
executed as it is defined (the default is to execute the commands
that follow while adding them to the macro definition).

The body of the macro can be parameterized by using the %X
construct where X is a digit from 1 to 9.  At macro execution,
the %X will be replaced with the macro parameters.  To specify
the value to use for a parameter during macro definition or if
the parameter is defaulted, follow the %X with [value].  For
example, the sequence:
        -macbegin node4x4
        -defnode %1[overglass-node] size 4 4
        -macend
will define a macro called "node4x4" which takes one argument:
a primitive node name.  The definition of the macro will be
executed and will set the verglass-node to default to 4x4 in
size.  Instantiations of the macro such as:
        -node4x4 transistor
will then set the transistor node to default to 4x4 in size.

The macro of commands is terminated with "macend".
Execution of a macro can be terminated with "macdone".
Macros are executed by invoking their name.
Macros can be attached to keys, buttons, and menus with "bind".
Macros can be renamed with "rename".
For information about existing macros, use "show macros".
For other variable substitutions, see "var".

!macdone command

This command, when executed inside of a macro, causes all
subsequent commands in that macro to be skipped.  It thus
returns prematurely from the macro.

The macro of commands is defined with "macbegin" and "macend".
Macros are executed by invoking their name.
For information about existing macros, use "show macros".
Macros can be attached to keys, buttons, and menus with "bind".

!macend command

This command marks the end of a collection
of commands that are to be grouped together into a macro.

The macro of commands is initiated with "macbegin".
Execution of a macro can be terminated with "macdone".
Macros are executed by invoking their name.
For information about existing macros, use "show macros".
Macros can be attached to keys, buttons, and menus with "bind".

!menu command

This command controls the display of the menus.  The format is:
        -menu on | off
        -menu [top | bottom | left | right]
              [size (auto | (COLUMNS ROWS))]
        -menu popup NAME size SIZE
        -menu popup NAME header MESSAGE
        -menu setmenubar [POPUPS]
        -menu dopopup [COMMAND]

"on" and "off" control the display of the fixed menu on the
screen.

"top", "bottom", "left" and "right" indicate that the fixed menu
is to be displayed in that location on the screen.

"size" indicates that the fixed menu should be COLUMNS by ROWS in
size.  If the keyword "auto" is used, the size is automatically
computed to be right for the current technology.

"popup" indicates that a pop-up menu called NAME is to be
modified.  The "size" option indicates that the menu will contain
SIZE entries and will be created if it does not exist.  The
"header" option sets the menu header to the string MESSAGE.

"setmenubar" allows the POPUPS to be attached to pulldown menus.
With no arguments, it turns the menu bar off.

"dopopup" causes pop-up menu execution of the specified COMMAND.  If
no COMMAND is given, pop-up menu execution begins with command
selection.

To examine or set the entries in the menu, use "bind".
To invoke a popup menu, issue its name.

!mirror command

This command mirrors the currently highlighted node along a
specified axis.  The format is:
        -mirror horizontal | vertical
        -mirror (horizontal | vertical) about-grab-point
        -mirror (horizontal | vertical) about-trace-point
        -mirror (horizontal | vertical) sensibly

"horizontal" indicates horizontal mirroring (about the X axis)
causing the top and the bottom parts of the node to be exchanged.

"vertical" indicates vertical mirroring where the left and right
sides of the node are exchanged.

The optional "about-grab-point" indicates that mirroring should
be done about the grab-point of the node rather than its center.

The optional "about-trace-point" indicates that mirroring should
be done about the currently highlighted outline point of the node
rather than its center.  If no outline point is highlighted, the
first is used.  The node must have outline information.

The optional "sensibly" indicates that the mirroring should go
about the center, unless there is a grab-point explicitly placed,
in which case use that.

All arcs connected to that node will alter to stay connected to
the node.  It may be necessary to move other nodes as well if
they are attached with the appropriate style of arc.

To specify the node to be mirrored, use "find".
To specify outline information, use "node".
To specify the default orientation for new nodes, use "defnode".
To set arc style, use "arc".

!move command

This command moves the currently highlighted objects.
The format is:
        -move
        -move (left | right | up | down) AMOUNT
        -move to X Y
        -move angle ANGLE
where the command with no arguments moves the currently
highlighted objects to the location of the cursor.  If the node
is a facet, its grab point is moved to the location of the
cursor.  If the selected object has a snap-point, that point is
moved to the location of the cursor.

"left", "right", "up", and "down" indicate that the current
objects are to be moved by AMOUNT in that direction (the default
distance is 1).

"to" indicates that the objects will move to the coordinates
(X, Y).

"angle" indicates that the objects will move along a line at an
increment of ANGLE degrees from its current location.

When moving nodes, it may be necessary to stretch and shift
connecting arcs and to move other nodes if they are attached
with the appropriate style of arc.

To specify the objects to be moved and a snap point, use "find".
To set arc style, use "arc".

!node command

This command modifies the characteristics of the currently
highlighted node instance.  The format is:
        -node [not] expand [DEPTH]
        -node name LOCALNAME
        -node not name
        -node trace [wait-for-down] [store-trace]
        -node trace add-point [X Y] | move-point [X Y] |
                    delete-point
        -node trace (next-point | prev-point)
        -node trace construct-annulus INSIDE OUTSIDE
                                      [SEGMENTS [DEGREES]]
        -node trace fillet
        -node regrid-facet
        -node cover-implant

"expand" indicates that the contents of the currently highlighted
facets are to be displayed (and objects inside of them are also
displayed) with DEPTH more levels of visualization than is
currently displayed.  If the depth is not specified, it defaults
to infinity (everything within the highlighted area is shown).
The normal method of display is un-expanded in which facets are
shown as empty boxes with port connections.  The "not expand"
form sets the opposite display.

"name" indicates that the currently highlighted node's name
should be LOCALNAME.  This name is not to be confused with the
name of the node prototype: it is simply a local identifier used
to distinguish the nodes from others in the facet.  The
"not name" form removes the name.  The name of the currently
highlighted node can be accessed with: $~.node_name, which is
useful in macros.

"trace" is used to set outline information in nodes that can be
polygonally defined.  Such nodes include the pure-layer nodes of
the layout technologies, most MOS transistors (to make them
serpentine), and the polygon nodes of the artwork technology.
The command with no parameters reads a continuous cursor outline
while any button is held down.  The "wait-for-down" option
actually waits for the button to be pushed (useful if the command
was issued from a button push such that the button is already
down).  The "store" option stores this outline information on the
currently highlighted node (in all cases, the information is left
in the command interpreter variable %T).

Single points of an outline can be modified with "add-point" which
adds the current cursor location to the outline (or the specified
coordinates if they are given), "move-point" which moves the
current outline point to the location of the cursor (or the
specified coordinates if they are given), and "delete-point"
which deletes the current outline point.

To move around the outline, use the "next-point" and "prev-point"
options.

A special case of outline setting is the "construct-annulus" option
which places a ring-shaped structure in the current node.  The
inside diameter of the ring is given in INSIDE, the outside
diameter is in OUTSIDE, the number of segments to use when
approximating a circle may be given in SEGMENTS (it defaults to
16), and the number of degrees of the circle to construct is
DEGREES (it defaults to 360).

Another special command is "fillet" which takes two polygonally
defined nodes, finds the line segments in the two that are
closest, and modifies them so that they intersect.

The "regrid-facet" option adjusts the position of all objects in
the current facet so that they sit on proper alignment boundaries.

The "cover-implant" option creates pure-layer nodes of implant to
cover the nodes and arcs that have such implants.  Previous pure-
layer nodes are removed, and the new ones are made hard-to-select
(and left highlighted).

To specify the node to be modified, use "find".
To specify an outline point on a node, use "find vertex".
Node names are also set by the "array" command.
Commands for dealing with macros are "macbegin" and "macend".
Variables can be manipulated with "var".

!offaid command

This command turns an aid off.  The format is:
        -offaid AID [permanently]

where AID is the name of an aid that is running (the default
state for most interactive aids).  If the "permanently" option is
given, this ommand is not undoable (useful if an aid acts
incrementally such that "undo" only fires a new action).

The command that reverses this is "onaid".
To give specific instructions to an aid, use "tellaid".
To see a list of aids, use "show aids".

!onaid command

This command turns an aid on.  The format is:
        -onaid AID [no-catch-up]

where AID is the name of an aid that is not running.  Incremental
aids will catch up with changes that have been made while they
were off.  If the "no-catch-up" switch is given, this action
will be supressed.

The command that reverses this is "offaid".
To give specific instructions to an aid, use "tellaid".
To see a list of aids, use "show aids".

!outhier command

This command edits a higher level of hierarchy from the current
facet.  The format is:
        -outhier [COUNT]

where COUNT, if specified, is the number of levels of
hierarchical depth to climb out.  If not specified, one level is
assumed.  The display changes to show the contents of the parent
facet.  If an export is selected, and only one level of
hierarchy is specified, the port path is followed.  This may
result in a popup menu listing the possible choices up the
hierarchy.

This command recalls the hierarchical path created by a sequence
of editfacet" commands.

!package command

This command packages the objects in the highlighted area into a
new facet.  The format is:
        -package NEWNAME

where NEWNAME is the name of a new facet that is to be created
with the objects in the highlighted area.  The current facet is
left untouched.  All nodes in the highlighted are packaged.
Those arcs connecting nodes that are both in the highlighted
area are also packaged.

To specify the area to be packaged, use "find".
For the opposite operation, which replaces a facet with its nodes
   and arcs, use "yanknode".

!port command

This command manipulates the characteristics of ports in the
current facet. The format is as follows:
        -port export PORTNAME [specify | (use PORT)]
                              [always-drawn] [body-only]
                              [input | output | bidirectional |
                               power | ground | refin | refout |
                               clock | clock1 | clock2 | clock3 |
                               clock4 | clock5 | clock6]
        -port not export [specify | (use PORT) | all | geometry]
        -port re-export-all
        -port highlighted-re-export
        -port identify
        -port synchronize-library LIBRARY
        -port move [remain-highlighted]
        -port change [specify | (use PORT)] [always-drawn]
                     [body-only]
                     [input | output | bidirectional | power |
                      ground | refin | refout | clock | clock1 |
                      clock2 | clock3 | clock4 | clock5 |
                      clock6 | none]
        -port labels [none | short | long | cross]

"export" indicates that a port on the currently highlighted node
is to be exported so that it becomes an export on the current facet.
The name of the export on the current facet will be PORTNAME which
should be unique among other exports on the current facet (if not,
letters will be added to the end of it so that it is unique).

"not export" indicates that an port, exported from the currently
highlighted node, should be removed as an export on the current
facet.

"re-export-all" indicates that all ports in the current facet
that are not connected or already exported should be exported.
This includes only those ports that are on facets (not
primitives) and have therefore already been exported one level.

"highlighted-re-export" indicates that all ports in the
highlighted area should be re-exported (if not already exported
and not connected and not on primitives).

"identify" causes all ports in the current facet to be shown.
The display is temporary, and goes away when the facet is redrawn.

"synchronize-library" examines library LIBRARY and finds facets
there with the same name as facets in the current library.  All
exports in these facets are then copied to the current library.
This is useful when two libraries are imported, and one has
exports but the other doesn't.

"move" causes an export to be moved from one node to
another.  Both nodes and their respective ports must be selected:
the source port is found with "find port" and the destination
port is found with "find more port".  The "remain-highlighted"
option keeps both nodes highlighted.

"change" indicates that a export, from the currently
highlighted node, should have its characteristics changed.

"labels" indicates how port labels should be displayed on the
screen.  The options are "none" which causes nothing to be
displayed at the ports, "cross" which causes small plus-signs
to be displayed, "short" (the default) which forces the short
port name to be displayed, and "long" which forces the full
port name to be displayed.  The difference between "short" and
"long" port names is that short names stop at the first
nonalphanumeric character.  If no port label style is given,
the current port style is printed.

For the "export", "not export" and "change" options, the command
will attempt to determine which port on the currently highlighted
node is the port under consideration.  The following options
will help with that selection.

"specify" indicates that all of the ports on the currently
highlighted node should be enumerated and that the user should
be given the chance to select one of them.

"use" indicates that the port named PORT on the currently
highlighted node is to be affected.

"all" indicates that all ports on the currently highlighted
node are to be affected (only valid with the un-export option).

"geometry" indicates that only exports in the highlighted area
will be removed.

For the "export" and "change" options, a number of
characteristics may be attached to the export.
These are the options:

"always-drawn" the export name should always be printed (even when
   the facet is expanded).
"body-only" the export should not be included on icon views of the
   facet.
"input" the export is an input signal to the current facet.
"output" the export is an output signal to the current facet.
"bidirectional" the export is a bidirectional signal to the current
   facet.
"power" the export is a power source to the current facet.
"ground" the export is a ground source to the current facet.
"refin" the export is a bias-level reference input to the current
   facet.
"refout" the export is a bias-level reference output to the current
   facet.
"clock" the export is a clock signal to the current facet.
"clock1" the export is clock phase 1 to the current facet.
"clock2" the export is clock phase 2 to the current facet.
"clock3" the export is clock phase 3 to the current facet.
"clock4" the export is clock phase 4 to the current facet.
"clock5" the export is clock phase 5 to the current facet.
"clock6" the export is clock phase 6 to the current facet.

To specify the node whose port is to be altered, use "find".
To change the name of an export, use "rename".

!quit command

This command exits from the design aid.  The format is:
        -quit

If changes have been made that would be lost by quitting, you
are asked to confirm that you want to quit.

To find out which libraries have been changed, use "show
   libraries".

!redraw command

This command re-displays everything on both the status and the
editing screens.  The format is:
        -redraw [DISPLAY | * | windows]

If DISPLAY is specified, the screen is redrawn on some other
display device known to the graphics package (this only works on
a VAX).  The device "*" indicates a reinitialization of the
display.  The keyword "windows" requests that only the windows be
redrawn.  In the default case, the screen is simply redrawn
which is useful if you suspect that its contents are incorrect.

!rename command

This command changes the name of virtually anything in the system
that has a name.  The format of the command is:
        -rename OLDNAME NEWNAME [WHICH]

where OLDNAME is the name of an existing object and NEWNAME is
the name to which it will be changed.  The command can change the
name of any object in the Electric database.  If there is more
than one object with the old name, the parameter WHICH will
decide which variable to change (p: primitive node prototype, c:
cell, a: arc prototype, r: export in the current facet,
l: library, t: technology, d: command name, m: macro name, u:
popup menu name, n: network name, or v: database variable).  If
the parameter is missing and there is ambiguity, you will be
prompted for the particular one to rename.

To see lists of most object names, use "show".

!replace command

This command replaces the currently highlighted node or arc with
another in its place with all connecting components intact.
The format is:
        -replace NEWTYPE [connected | this-facet | universally |
                          ignore-port-names]

where NEWTYPE is the new node or arc prototype that is to be
inserted where the currently highlighted object resides.  For
nodes, the new one must have ports at the same position as the
old one so that the arcs can be run to he same locations.  For
arcs, the new arc must be able to connect to its two nodes.

The "connected" option will replace all objects of the currently
highlighted prototype with the new prototype, provided that they
are electrically connected to the highlighted object.

The "this-facet" option will replace all objects of the currently
highlighted prototype with the new prototype, throughout this
facet.

The "universally" option will replace all objects of the
currently highlighted prototype with the new prototype,
throughout the library.

The "ignore-port-names" options specifies that ports on replaced
nodes will be aligned by position only, and not their names.

To specify the node or arc to be replaced, use "find".

!rotate command

This command rotates the currently highlighted node.  The format
is:
        -rotate interactively
        -rotate ANGLE [more [sensibly]]
        -rotate ANGLE [more [about-grab-point | about-trace-point]]

The "interactively" option causes graphic selection of the new
angle by attaching a rotating box to the cursor.

ANGLE is the new angle of rotation, in degrees.  If "more" is
specified, the new angle is ANGLE degrees more than the current
angle.

The "sensibly" option causes rotation of facet instances with
facet centers to be done about that facet center.

The "about-grab-point" option requests that the rotation go about
the grab-point rather than the node center.  If there is a snap
point selected, rotation goes about that.

The "about-trace-point" option requests that the rotation go
about the currently highlighted outline point rather than the node
center (the node must have outline information; if there is no
currently highlighted outline point, the first is used).

All arcs connected to the node will alter to stay connected to
the node.  It may be necessary to move and rotate other nodes as
well if they are attached with the appropriate style of arc.

To specify the node to be rotated and a snap point, use "find".
To set arc style, use "arc".
To set outline information, use "node".
To specify the default rotation for newly created nodes, use
   "defnode".

!show command

This command prints descriptive information.  The format is:
        -show aids
        -show bindings keys | menus | (popups [MENU]) | buttons |
                       all | short
        -show cells [library LIB] [matching WILDCARD]
        -show dates [FACET]
        -show environment [authors]
        -show error (current | next | last)
        -show facets [dates] [edit] [library LIB]
                     [matching WILDCARD] [file FILE]
        -show facets graphically
        -show facets contained-in-this
        -show history [BATCH]
        -show libraries
        -show macros [MACRO]
        -show networks
        -show object [short | long]
        -show ports [PORTTYPE]
        -show primitives
        -show solvers
        -show technologies
        -show usage FACET
        -show views [CELL]

"aids" prints a list of analysis and synthesis aids along with
their current status.

"bindings" is used to print command bindings.  It requires one of
the parameters "keys", "menus", "popups", or "buttons" and prints
current bindings to keys, menu entries, popup menus, or mouse
buttons.  The "all" option prints all of the above information
and the "short" option briefly lists the commands bound to the
mouse buttons and single keys.  The "popups" option can take an
optional popup menu name to print its contents only.

"cells", with no options, prints a list of cells in the current
library.  The "library" option causes the list of cells to be
made on library LIB.  The "matching" option causes only those
cells matching the WILDCARD to be listed (the wildcard may have
"?" and "*" to match any character and any string).

"dates" prints the creation date, revision date, and revision
number of the current facet.  If a FACET is specified, that
facet's information is given.

"environment" prints general information about this version of
Electric.  The "authors" options lists all people who have
contributed to the code.

"error" prints errors from tools (such as DRC, ERC, or NCC).
The "next" option shows the next error; the "prev" option shows
the previous error; and the "current" option repeats the current
error.

"facets", with no options, prints a list of facets in the current
library.  The "dates" option includes facet creation and revision
dates.  The "edit" option uses an editing window on the facet
names (in which the M(=) key will edit the facet on the current
line).  With either of these options, the "library" or "matching"
options can be used, as described in the "show cells" section
above.  The "file" option (not available with the "edit" option)
causes the list to be saved in a disk file (tab-separated, for
spreadsheets).  Two final options must stand alone: "graphically"
produces a graph showing the hierarchical organization of facets
in the current library, and "contained-in-this" prints a list of
subfacets immediately inside of the current facet.  For a
hierarchical list of facets inside the highlighted facet
instance, use "show object long".  

"history" prints a list of changes that have been made.  If a
BATCH number is given, full details are printed about that batch
of changes.

"libraries" prints a list of libraries.

"macros" prints a list of macros.  If MACRO is specified, the
commands in that macro are printed.

"networks" prints a list of networks in the current facet.

"object" prints information about the currently highlighted
object.  If the "short" option is used then less information is
printed.  If the "long" option is used then more information is
printed.

"port" prints the names of the PORTTYPES requested.  Valid type
names are the standard export types ("input", "power", etc.)
The default option is "all", and lists all export types including
generic.

"primitives" prints the current primitive node prototypes in the
current technology.

"solvers" prints a list of constraint solvers.

"technologies" prints a list of technologies.

"usage" prints a list of superfacets that include instances of
the specified facet.

"views" prints the current list of views.  If a CELL is given,
all view associations for that cell are listed.

Aids can be controlled with "offaid", "onaid", and "tellaid".
Facets can be manipulated with "editfacet" and "killfacet".
Changes can be manipulated with "undo".
Libraries can be manipulated with "library".
Macros can be manipulated with "macbegin" and "macend".
Constraint solvers can be manipulated with "constraint".
Technologies can be manipulated with "technology".
Views can be manipulated with "view".
All objects can be renamed with "rename".

!size command

This command changes the size of the currently highlighted node
or arcs.  The format for a node is:
        -size XSIZE YSIZE [use-transformation]
        -size center-fixed
        -size corner-fixed

where XSIZE is the new X dimension of the node and YSIZE is the
new Y dimension of the node.  For nodes that have highlighted
areas smaller than the entire node (such as MOS transistors),
specify the size of that highlighted area and not the entire node.

"use-transformation" indicates that any transformation on the
node should be applied before setting the size, so that the size
values make sense with respect to their displayed orientation.

"center-fixed" causes the node to be expanded to the cursor
position, while holding the node center at a fixed position.
This means that all four corners of the node will move by the
same amount away or towards the node center.

"corner-fixed" causes the node to be expanded so that the corner
closest to the cursor moves to the cursor and the opposite corner
remains fixed.  All arcs connected to the node will alter to stay
connected to the node.  It may be necessary to move other nodes
as well if they are attached with the appropriate style of arc.

For one or more arcs, the format is:
        -size WIDTH
        -size center-fixed
where WIDTH is the new arc width.

"center-fixed" will stretch the arc so that the closest edge to
the cursor is brought to the cursor and the other edge is moved
by the same amount.  This option can only accept one highlighted
arc.

To specify the node or arcs whose size is to be changed, use
   "find".
To specify the default size of newly created nodes and arcs,
   use "defarc" and "defnode".
To set arc styles for constraint propagation, use "arc".
Other commands that modify nodes are "move", "rotate", and
   "mirror".

!spread command

This command spreads open the facet along an axis running through
the currently highlighted node.  The format is:
        -spread left | right | up | down [AMOUNT]

where the arguments "left", "right", "up" and "down" cause space
to be inserted in that direction from the current node.  For
example, "right" causes all layout to the right to be pushed
along the horizontal axis.  The amount of the spread defaults
to the current design-rule spacing for that particular node but
may be specified as AMOUNT.  Negative values of AMOUNT will
compact.

To specify the spread pivot node, use "find".
Real compaction can be done with the compaction aid.

!system command

This command allows you to issue commands that are specific to the
current operating system.  The format is:
        -system OPTION

where the OPTION may be "setstatusfont" on the Macintosh or Windows
to change the messages window font.  On Windows, you may also use
"print" to print the current facet.

!technology command

This command works with technologies: the environments of design.
The format is:
        -technology use TECHNAME
        -technology autoswitch (on | off)
        -technology convert TECHNAME
        -technology document TECHNAME
        -technology tell TECHNAME MESSAGE
        -technology kill TECHNAME
        -technology edit [OPTIONS]

where the "use" option causes the default design technology to
switch to TECHNAME.  Although one library can have facets in
different technologies, only one technology can have its color
map loaded at a time.  Therefore, facets in technologies other
than the current one may appear with strange colors.

The "autoswitch on" option requests that the current technology
automatically switch to match the current facet.  "autoswitch off"
reverts to manual technology switching.

The "convert" option causes the current facet to be converted to
technology TECHNAME.  The current technology is not altered.
This option does not work with all combinations of technologies
and in fact is currently only able to translate from MOS to
schematic or between similar MOS technologies.

The "document" option causes a disk file to be written that
describes technology TECHNAME.  The file is called "TECHNAME.doc".

The "tell" option causes the MESSAGE to be sent to technology
TECHNAME.  The meaning of these messages is technology specific.
Currently, only the mocmos technology accepts this option.  In
general, this option is not undoable.

The "kill" option deletes the named technology.  This option is
not undoable.

The "edit" option allows technology editing by converting
technologies to libraries, editing the libraries, and converting
the libraries back to technologies.  You can also create a new
library that defines a technology.

For more detail on technology editing, use "help tecedit".
To see a summary of the technologies, use "show technologies".

!tellaid command

This command sends information to an aid.  The format is:
        -tellaid AID MESSAGE

where AID is the name of a synthesis or analysis tool and MESSAGE
is specific to that aid.  In general, the results of this command
are not undoable.  The current set of aids is as follows:
    user             execute the command in MESSAGE
    io               send MESSAGE to I/O aid
    compaction       send MESSAGE to compaction aid
    pla              send MESSAGE to PLA aid
    routing          send MESSAGE to routing aid 
    silicon-compiler send MESSAGE to silicon place-and-route aid
    vhdl-compiler    send MESSAGE to VHDL compiler aid
    network          send MESSAGE to network aid
    drc              send MESSAGE to drc aid
    simulation       send MESSAGE to simulation aid

To start and stop aids, use "onaid" and "offaid".
See help sections for specific tools.

!terminal command

This command controls characteristics of the status display and
all input.  The format is:
        -terminal
        -terminal length VALUE
        -terminal width VALUE
        -terminal input LETTER PROMPT [STYLE]
        -terminal more (on | off)
        -terminal [not] lock-keys-on-error
        -terminal [not] only-informative-messages
        -terminal [not] display-dialogs
        -terminal [not] permanent-menu-highlighting
        -terminal [not] use-electric-commands
        -terminal [not] track-cursor-coordinates
        -terminal [not] beep
        -terminal session playback FILE [all]
        -terminal session begin-record
        -terminal session end-record
        -terminal session rewind-record
        -terminal session checkpoint-frequency [FREQ]

Where the command with no arguments prints the current status
display length and width.  If the keywords length or width are
specified, the next value is the new number of lines down or
across on the status display.

The "input" option causes a keyword to be read from the terminal
and stored in the command interpreter variable LETTER.  The user
will be first prompted with the string in PROMPT.  Command
completion will be done if STYLE is specified in which case it
should be one of the keywords "about", "alignment", "area",
"array", "annulus", "artlook", "attributes", "capacitance",
"change", "chglibrary", "cifopt", "compopt", "copyfacet",
"defarc", "defnode", "deftext", "dependentlibs", "depth3d",
"defopt", "drcopt", "dxfopt", "edifopt", "editfacet", "edtecarc",
"edteclayer", "edtecnode", "facet", "facetinfo", "file",
"frameopt", "gain", "gdsopt", "grid", "help", "highlayer",
"iconopt", "inductance", "labels", "lambda", "layerpatterns",
"layers", "libopt", "library", "libtotech", "menu", "netopt",
"newview", "node", "noyes", "ofile", "optionsave", "path",
"plot", "port", "purelayer", "resistance", "routeopt",
"selectnode", "selectopt", "silcomp", "skillopt", "showdetail",
"show", "siemens", "simopt", "spice", "spread", "technology",
"techsettings", "techvars", "trace", "variable", "verilog",
"vhdlopt", "view", "visiblelayers", "widlen", or "windowview".

"more" controls pausing of the status terminal when it is full of
new messages.  When "off", the messages will be printed with no
pause.  When "on" (the default), it will stop after a screenful.
Type space to see another screen, carriage-return to see one more
line, and 'q' to stop output.

"lock-keys-on-erro" indicates that the single-key commands should
be disabled after any error (this is the default state).  This
feature is disabled with "not lock-keys-on-error".

"only-informative-messages" indicates that terminal output should
be restricted to those messages that clarify or correct.  Purely
status messages that the user probably already knows are
supressed.  This feature is disabled (the default state)
with "not only-informative-messages".

"display-dialogs" indicates that special-case graphical dialogs
should be used instead of command completion whenever possible.
This feature is disabled (the default state) with
"not display-dialogs".

"permanent-menu-highlighting" indicates that highlighting of the
fixed menu will stay permanently (the default state) and will
reflect the current node and arc types.  The alternate state
is to highlight menu entries when they are selected and remove
the highlighting when the command is completed.

"use-electric-commands" indicates that the system may refer to
actual Electric commands in conversation (this is the default).
When macro packages have heavily redefined the command interface,
it is preferable to disable this feature (with "not
use-electric-commands") so that irrelevant command names are not
used.

"track-cursor-coordinates" indicates that the status display
should show the X and Y coordinates rather than the current
technology and lambda value.  The reverse of this is the default
(show the technology and lambda values).

"beep" indicates whether the system will make beeps on errors
and for other attention-getting purposes.

The "session" option controls recording and playback of all input
activity.  By default, sessions are recorded in the file
".electric_log" unless Electric is invoked with the -n option.
The "playback" option will read the session log in FILE and
execute it (if the keyword all appears after the file name, the
entire file is played back immediately).  The "begin-record"
option starts logging and the "end-record" option terminates
session logging.  The "rewind-record" option erases any logging
done so far and starts the log file at the beginning (this is
done whenever libraries are saved on disk).  Finally, the
"checkpoint-frequency" option will set the number of keystrokes
or button pushes between flushes to the session log file to be
FREQ.  Without an argument, the current value will be printed
(default is 10).  This command is not undoable.

To manipulate command interpreter variables, use "var".

!text command

This command performs miscellaneous manipulations on text
objects.  The format is:
        -text style [NEWSTYLE]
        -text size (NEWSIZE | up | down)
        -text default-style [NEWSTYLE]
        -text default-size (NEWSIZE | up | down)
        -text default-horizontal-style [none | inside | outside]
        -text default-vertical-style [none | inside | outside]
        -text editor [EDITOR]
        -text (easy-text-selection | hard-text-selection)
        -text cut | copy | paste | find STRING
        -text (read | write) FILE
        -text (interior-only | exterior)
        -text (default-interior-only | default-exterior)

"style" modifies the grab-point of the currently highlighted text.
If a NEWSTYLE is mentioned, that value is used (either centered,
"boxed", "up", "down", "left", "right", "up-left",
"up-right", "down-left", or "down-right").  Otherwise, the
cursor location is used to determine the grab-point.

"size" modifies the size of the currently highlighted text.  The
value of NEWSIZE can be one of the absolute scales "4p", "6p",
"8p", "10p", "12p", "14p", "16p", "18p", or "20p".  It can
also be one of the relative scales small, medium, or large.
The two options "up" and "down" change the scale by one step.

"default-style" manipulates default grab-points for all
subsequently created text.  If a NEWSTYLE is mentioned, that
style becomes the new default.  Otherwise, the current default
style is printed.

"default-size" manipulates default size for all subsequently
created text.  If a NEWSIZE, "up", or "down" is mentioned, that
becomes the new default size.  Otherwise, the current default
size is printed.

"default-horizontal-style" and "default-vertical-style"
manipulate the smart placement of export labels.  The "inside"
and "outside" options override the default style to force the
export label to be intelligently placed according to the location
of connecting arcs.

"editor" reports the type of text editor that will be used.  If
an EDITOR is specified, that becomes the current text editor.

"easy-text-selection" (which is the default) indicates that the
"find" command will be able to select all text displayed in a
facet.  The "hard-text-selection" option indicates that the
"find" command will not be able to select node or arc text
unless the "port" option is NOT specified.  This means that a
typical "find" command will only be able to select export
names.

"cut", "copy", and "paste" are context-dependent.  If the current
window is an editing window, objects are cut, copied, and pasted.
If the current window is a text edit window, text is manipulated.
"cut" places the selected objects in a scrap buffer and removes
it from the display.  "copy" does the same without removing the
objects.  "paste" places the contents of the scrap buffer back
into the display.

"find" searches for the next occurence of STRING and leaves the
selection over it.

"read" and "write" move the text in the current window's text
editor to and from disk.  The "read" option replaces the edit
buffer with the contents of FILE, and the "write" option saves
the edit buffer to the specified FILE.  These commands are not
undoable.

"interior-only" and "exterior" control whether the text is shown
when instances of the current facet are expanded.  By default,
the text is shown, but with "interior-only" it is not.

"default-interior-only" and "default-exterior" control whether
default text is shown when instances of the current facet are
expanded.  By default, the text is shown, but with
"default-interior-only" it is not.

To see information about the currently highlighted text, use
   "show object".

!undo command

This command undoes most previous changes.  The format is:
        -undo [COUNT]
        -undo save TOTAL

where COUNT is a number of changes to undo.  The default is to
undo the last user command.  When the current window is a text
editor, only 1 change can be undone, and the change is not
visible on the batch list.

"save" indicates that TOTAL changes should be saved for undoing.

To find out what is available for undoing, use "show history".
Most commands can be undone.  Only very extensive commands, and
those that write disk files, cannot be undone.  In particular,
these commands cannot be undone: "constraint tell",
"library {read/write/save/kill/use}", "technology {tell/kill}",
"tellaid", and "terminal {audit/session}".

!var command

This command manipulates attributes either inside the command
interpreter or on database variables.  The format is:
        -var
        -var examine VARIABLE
        -var change VARIABLE [not] MODIFIER
        -var delete VARIABLE
        -var pick VARIABLE
        -var textedit VARIABLE
        -var set VARIABLE VALUE [MODIFIER]
        -var OPERATOR VARIABLE VALUE [MODIFIER]
        -var vector DEST SOURCE1 (set|concat|select|pattern|type)
                        [SOURCE2]
        -var options [ignore | track]
        -var reinherit

Command interpreter variables are those that begin with a % sign
and database variables are those that begin with a $.  A command
interpreter variable is a single letter from a to z or from A to
Z.  Database variables are much more complex (see Attribute help).

If this command is issued with no arguments, it prints the value
of all command interpreter variables that are set.

"examine" displays the value of the mentioned VARIABLE.

"change" modifies the nature of the mentioned VARIABLE.  The
MODIFIER affects the value setting as follows: "lisp" makes the
variable LISP code, "tcl" makes the variable TCL code,
"java" makes the variable JAVA code, "not language"
makes the variable be static (not code), "[not] display" changes
the visibility of the variable on the object, "[not] temporary"
affects whether the variable is saved on disk, and "[not]
cannot-change" affects whether the variable is read-only.

"delete" deletes the specified VARIABLE.

"pick" allows menu selection of attributes on the specified
VARIABLE.

"textedit" allows you to interactively edit the array attribute
VARIABLE in a text editor window.

"set" will set the VARIABLE to the VALUE.  In addition to
set, it is possible to mention one of eight OPERATOR values
("+", "-", "*", "/", "mod", "|", "and" or "or")
which will modify the VARIABLE by the VALUE.  "|" is string
concatenation.  The optional MODIFIER affects the value setting
as follows: "lisp" makes the variable LISP code, "tcl" makes the
variable TCL code, "java" makes the variable JAVA
code, "display" causes the variable to be displayed on the object,
"temporary" makes the variable temporary (not saved on disk),
"fractional" makes the variable fixed-point and "cannot-change"
makes the variable read-only.  After the "display" option, you
may provide two numbers which are the offset of the displayed
variable, relative to the center of the object on which it is
displayed.

"options" controls whether changes to option variables will be
tracked so that the user will be prompted to save those options
on exit.  "ignore" indicates that subsequent option variable
changes will be ignored, and "track" (the default) indicates that
subsequent option variable changes will cause option saving to
be offered.

"reinherit" causes the currently selected node to examine all
inheritable attributes on its prototype (both node and export) for
any new attributes that should be inherited and weren't already.

Example:
var set ~.proto.width-in-lambda 12
var set a $~.proto.width-in-lambda
var + a 4
defnode $~.proto size $~.proto.width-in-lambda %a

This creates a new slot called width-in-lambda in the currently
highlighted object's prototype and sets that slot to the value
12.  It then copies this value to the command interpreter
variable %a and adds 4 to it.  Finally, it sets the default size
of all newly created instances of this prototype to be 12 by 16.

To create macros of commands, use "macbegin" and "macend".
For conditionals, use "if".
To manipulate language code, use "interpret".

!view command

This command handles the different views of a cell.
        -view change FACET NEWVIEW
        -view new NEWVIEW [ABBREVIATION [text]]
        -view delete VIEW
        -view frame (a | b | c | d | e | none) [vertical]

"change" modifies the view type of facet FACET to NEWVIEW.

"new" creates a new view type called NEWVIEW which has the
abbreviation (used in facet names) ABBREVIATION.  If the keyword
"text" follows the abbreviation, this view is text-only (like the
"documentation", "vhdl", and many "netlist" views).

"delete" removes a view type (you can only remove those views
that you have created, and only if there are no facets using it).

"frame" controls the display of a schematic page frame in the
current facet.  The frame size may be "a" to "e" size, or
it may be turned off.  In addition, the optional "vertical"
parameter causes the page frame to be rotated.

To see the current list of view types, use "show views".

!visiblelayers command

This command controls which layers of the design are to be
visible on the screen.  The format is:
        -visiblelayers [LAYERS [no-list]]
        -visiblelayers * [no-list]
        -visiblelayers *-LAYERS [no-list]
        -visiblelayers -LAYERS [no-list]
        -visiblelayers +LAYERS [no-list]

where LAYERS is a collection of letters, one per layer that is
to be visible.  If LAYERS is omitted, a list of currently
visible layers is printed.  The option "*" causes all layers to
be visible.  The construct "*-LAYER" causes all layers except
for XXX to be made visible.  The construct "-LAYERS" causes
those layers to be removed from the list.  The construct
"+LAYERS" causes those layers to be added to the list.
Normally, all visible layers are printed after each command
unless the "no-list" option is given.

The color or pattern of a particular layer can be changed with
   "color".

!window command

This command controls the layout and contents of windows on the
editing display.  The format is:
        -window split [horizontal | vertical]
        -window (new | delete)
        -window adjust (horizontal-tile | vertical-tile | cascade)
        -window 1-window
        -window (kill | join)
        -window use WINDOW
        -window peek
        -window (in-zoom | out-zoom) [AMOUNT]
        -window all-displayed | highlight-displayed
        -window trace-displayed | (match WINDOW)
        -window (up | down | left | right) [AMOUNT]
        -window cursor-centered | center-highlight
        -window measure
        -window zoom-scale [integral | nonintegral]
        -window dragging [on | off]
        -window (save VIEWNAME | name VIEWNAME)
        -window tiny-facets (draw | hash-out [LAMBDAPERPIXEL])
        -window normal-cursor (standard | pen | tee)
        -window explore
        -window 3-dimensional (begin | end | rotate | zoom | pan)

"new" causes a new window frame (a window in the operating
system's window facility) to be created.  Subsequent "window"
commands will operate in this window frame.

"delete" causes the current window frame to be deleted.

"adjust" causes the window frames to be organized sensibly
("horizontal-tile" to tile horizontally, "vertical-tile" to tile
vertically, and "cascade" to cascade from upper-left to lower-right.

"split" indicates that the currently highlighted window should
be split into two windows.  The options "horizontal" and
"vertical" can control the direction of the split (only when
splitting the entire window).  Splitting can continue
indefinitely.

"1-window" indicates that there should only be one window on the
screen.

"kill" and "join" indicate that the currently highlighted window
should be combined with its adjoining window into one larger
window.  The "kill" option deletes the current window and the
"join" option deletes the other.

"use" indicates that the currently highlighted window should be
set to WINDOW.

"peek" indicates that the currently highlighted area is to be
completely displayed down to the bottom of the hierarchy.  This
display does not affect the node expand information and does not
remain when the window is moved or scaled.

"in-zoom" magnifies the contents of the currently highlighted
window by a factor of two (or by the specified amount).
Everything zooms-in and gets larger so that less of the design
is shown in the current window.

"out-zoom" shrinks the contents of the currently highlighted
window by a factor of two (or by the specified amount).
Everything gets smaller and more of the design is shown in the
current window.

"all-displayed" changes the contents of the currently highlighted
window so that the entire facet is centered and fills the window.

"highlight-displayed" changes the contents of the currently
highlighted window so that the currently highlighted area is
centered and fills the screen.

"trace-displayed" changes the contents of the currently
highlighted window so that the outline information in the command
interpreter variable %T is centered and fills the screen.

"match" indicates that the scale of display in the currently
highlighted window should be set equal to that in window WINDOW.

"up", "down", "left" and "right" indicate that the currently
highlighted window should have its contents shifted by AMOUNT.
The default is half of a screen size.  If the amount has the
letter "l" after it, the screen will be moved that many lambda
units rather than screen sizes.

"cursor-centered" changes the contents of the currently
highlighted window so that the cursor position is centered.
No change of scale is done.

"measure" allows you to measure the distance between two points
in the window by clicking at the first point and dragging (with
the button held) to the second point.  The distance is displayed
on the line.  This measurement goes away when the button is
released.

"center-highlight" changes the contents of the currently
highlighted window so that the currently highlighted area is
centered.  No change of scale is done.

"zoom-scale" controls the way editing windows are scaled.  When
"nonintegral" (the default), scaling may be arbitrary and
continuous.  When "integral", the window scale is adjusted so
that there are an integral number of pixels per lambda unit
(or an integral number of lambda units per pixel).  This makes
window panning and other graphics look better since the circuit
sits cleanly on pixel boundaries.  However, perfectly smooth
scaling is not possible.

"dragging" controls the style of cursor-based commands.  When
"off", the commands will act immediately on the current location
of the cursor.  When "on" (the default), they will interactively
show object locations and wait for a button release or keystroke
to actually complete the command.

"save" causes the current window zoom and pan information to be
saved with the name VIEWNAME.  The "name" option causes the
saved VIEWNAME view to be restored.

"tiny-facets" causes tiny facets to be drawn in the requested
style, either "draw" or "hash-out" (the default: contents are
not drawn).  If a LAMBDAPERPIXEL is specified, it is the number
of lambda per pixel above which facets are not drawn.

"normal-cursor" controls the appearance of the cursor when
command input is expected.  The possible options are "standard"
(the default), "pen" (to show a pen, typically for polygon edit
mode), and "tee" to show a "T" (typically in technology edit
mode).

"explore" toggles the facet explorer, a window that shows all
facets in hierarchically-indented text.

"3-dimensional" controls the display of 3D views of the circuit.
"begin" changes the window to a 3D display; "end" restores 2D
display; "rotate" causes cursor motion in a 3D display to rotate
the view; "zoom" causes cursor motion in a 3D display to zoom
the view; and "pan" causes cursor motion in a 3D display to pan
the view.

To specify the outline for the trace-displayed option, use "node
   trace".
To expand hierarchical nodes, use "node".

!yanknode command

This command extracts the contents of one or more facets to the
outer level.  The format is:
        -yanknode

The currently highlighted facet(s) are removed and replaced with
their contents.  Arcs to ports in the facets are replaced with
arcs to the actual nodes in that facet and exports on the
facet(s) are moved to their respective nodes inside that
facet(s).  Exports inside the facet(s) are not kept
unless the "defnode * copy-ports" command has been issued.

To specify the facet(s) to be yanked, use "find".
The opposite operation, which collects a group of nodes and arcs
   into a new facet, is "package".

!Arc properties

Arcs may have the following properties associated with them:

Directional arcs have an arrow that points from the tail to the
head of the arc.  By default, arcs do not have a direction.
The arc reverse command toggles the directionality and the arc
skip-head command controls the display of the arrow head.

Negated arcs have a negating bubble on the tail that indicates a
negation on the connecting node's port.  This only applies to
technologies where the option makes sense, such as "schematic".
The arc reverse command toggles which end has the negation and
the arc skip-tail command controls the display of the bubble.

Arcs with their ends-extended overlap their connection point by
half their width.  The arc skip-head and arc skip-tail commands
can exclude either end from being shortened.

!Attributes
Every object in Electric contains a set of attribute/value pairs
that are called database variables.  In addition to these
variables there are command interpreter variables that are
temporaries available for manipulation.

Command interpreter variables are substituted in any command that
uses the %X construct where X is a single letter from a to z or
A to Z.  In general, the lower case command interpreter variables
should be used when in doubt because the upper case letters are
used by various macro packages that know what they are doing.
Also, the "node trace" command stores its data in the command
interpreter variable %T.

Database variables are substituted in any command that uses the
$X or $(X) construct where X is a database variable as follows:
 QUAL [ .SPECS [ INDEX ] ]
 QUAL := NODE | PRIM | FACET | CELL | ARC | LIB | TECH |
         AID | NET | VIEW | CURRENT | OBJECT
 NODE := node:~ | node:NODE-IN-CURRENT-TECH-OR-LIB
 PRIM := prim:~ | prim:PRIMITIVE-NODE-IN-CURRENT-TECH
 FACET := facet:~ | facet:FACET-IN-CURRENT-LIBRARY
 CELL := cell:~ | cell:CELL-IN-CURRENT-LIBRARY
 ARC := arc:~ | arc:ARC-IN-CURRENT-TECHNOLOGY
 LIB := lib:~ | lib:LIBRARY-NAME
 TECH := tech:~ | tech:TECHNOLOGY-NAME
 AID := aid:~ | aid:ANALYSIS-OR-SYNTHESIS-AID-NAME
 NET := net:NETWORK-NAME-IN-CURRENT-FACET
 VIEW := view:VIEW-NAME
CURRENT := ~ | ~x | ~y | ~o | ~c | ~hl | ~hr | ~ht | ~hb |
            ~nodes | ~arcs | ~ports | ~nets | ~facets | ~libs
 OBJECT := NAME-OF-NODE-INSTANCE | NAME-OF-ARC-INSTANCE
 SPECS := SPEC | SPEC.SPECS
 SPEC := VARIABLE-NAME-APPLICABLE-TO-CURRENT-CONTEXT
 INDEX := "[" INTEGER "]"

In general, the ~ indicates the current object.  Thus, tech:~ is
the current technology, ~ is the currently highlighted object
(the first if there are many), ~x and ~y are the current X and Y
coordinates of the cursor, ~o is the other currently highlighted
object (if two are selected), ~c is the count of the number of
highlighted objects, and ~hl, ~hr, ~ht, ~hb are the left, right,
top, and bottom sides of the currently highlighted object.  The
forms ~nodes, ~arcs, ~ports, ~nets, ~facets, and ~libs give
arrays of the current nodes, arcs, exports, and nets in the facet,
current facets in the library, and current libraries.  Arrays may
be indexed with square brackets.

Examples:
 echo $tech:nmos.deflambda    prints the value of lambda for nMOS
 echo (%T[0],%T[1])           prints first coordinate of last
                              outline
 echo Cursor at $(~x),$(~y)   prints the current cursor position
 echo $~facets                prints a list of all facets

!Color map

256 entries in the color map, organized as follows:
   1: black grid (any value with this bit)
   2: white highlight (any value with this bit)

!Color map file

Color map files are composed of three parts: the header line,
the color map, and the bit-map information.

The header line is the first line and is simply the name of the
technology.  In old format files, the technology name is the
only thing on the line.  On newer format files (re-arranged color
map), the line begins with the word "technology=".

The color map consists of lines of text with four fields per
line.  The first three fields are the red, green, and blue
values for the color map (from 0 to 255).  The last field is the
high index into which this map entry will go.  This field must
ascend on each subsequent line and must be 255 on the last line.

After the color map, comes the bit maps for the layers.  The
first line gives the number of layers.  Following that are bit
descriptions, one layer per line.  Each line has a layer
identifying character followed by 8 16-bit numbers (in octal),
all separated by tabs.  These 8 numbers form a 16x8 bit field
for the layer.

The "color" command reads and writes these files.
For the meaning of the color map entries, use "help map".

  p                        pause simulator, return to Electric

!Hierarchical layout

When using the hierarchical layout constraint system (the
default), arcs may have the following properties:

Fixed-angle arcs must remain at a fixed angle so that when a
connecting node moves, the other node must also move to keep the
angle the same.  Non-fixed-angle arcs can change to any angle.

Non-rigid arcs can change length to accommodate changes to
connecting nodes whereas rigid arcs remain the same length and,
in addition, remain attached to their nodes at the same angle so
if a node rotates, its rigid arcs will spin about to remain
attached in the same place and configuration.

Temporary rigidity applies to the next change only, after which
the rigidity properties revert to their permanent state.

Slidable arcs are able to slide about within their port area so
that if the arc moves by a small amount, the node will not also
move.  Rigid arcs cannot slide and fixed-angle arcs can by
default.

!Linear inequalities

These commands may be given to the linear inequalities constraint
solver with constraint tell linear (remember, you must switch
to this solver first):
 solve [X]                 solve in facet X [current facet]
 implicit-manhattan on|off sets manhattan assumptions
 text-equivalence OPTION   set text-to-graphics system:
   go                      turn on text-to-graphics system
   name-nodes              generate text names for all nodes
   highlight-equivalent    show text equal to highlighted

When in the text editor window, the command Meta-= will highlight
the graphics associated with the current text line.  When the
text-to-graphics system is on, all changes to the text window
will be updated in graphics and visa-versa.

Arc constraints are inequalities of the form "X==C", "X>=C",
"X<=C", "Y==C", "Y>=C", or "Y<=C" where C is a constant.

To set constraints on arcs, use "arc constraint".
To switch to this constraint solver, use "constraint use linear".

 auto-naming [on | off]          set automatic network naming [off]
 re-number [X]                   reevaluate facet X [current]
 total-re-number                 reevaluate entire library

To issue these commands, use tellaid.  Pairs of nodes from
different facets can be equated prior to comparing to help the
process.

To name networks, use "arc name".

!Technology edit

The technology edit command has the following options.
        -technology edit (library-to-tech |
                          library-to-tech-and-C)
        -technology edit tech-to-library [TECHNOLOGY]
        -technology edit dependent-libraries [LIBS]
        -technology edit place-layer SHAPE
        -technology edit inquire-layer
        -technology edit change
        -technology edit change LAYERNAME
        -technology edit change ARCNAME (yes | no)
        -technology edit change port-angle ANGLE
        -technology edit change port-angle-range RANGE
        -technology edit change NEW-FIELD
        -technology edit edit-node NODENAME
        -technology edit edit-arc ARCNAME
        -technology edit edit-layer LAYERNAME
        -technology edit edit-subsequent
        -technology edit (edit-colors | edit-design-rules |
                          edit-misc-information)
        -technology edit identify-layers
        -technology edit identify-ports

The options "library-to-tech" and "library-to-tech-and-C"
convert the current library to a technology, optionally writing
C code.

The option "tech-to-library" converts existing technology
TECHNOLOGY into a library.  It defaults to the current technology.

The option "dependent-libraries" takes a list of library names
that this one will use when constructing a technology.  With
no parameter, the list is printed.  If the parameter is "-",
the list is cleared.  Dependent libraries are scanned in reverse
order, from the last entry in the list back to the first, with
the current library implicitly coming before any dependent
libraries.  Any information in a library that is not in a more
recent library is included in the technology.  This enables
hierarchies of technologies to be created that have base
descriptions and multiple levels of customization.  It is the
final customization library that contains the dependent library
list, and this list begins with the base library and continues
up to, but not including, the final customization library.

The option "place-layer" creates a patch of material of a given
SHAPE.  The two shapes "port" and "highlight" create port objects
in node and highlight boxes for both nodes and arcs.  For normal
geometry, the change option should be used to set the desired
layer for the material, once placed.

The option "inquire-layer" provides information about the
currently highlighted object.  This object is presumed to be in
a technology-library.

The option "change" varies according to what is currently
highlighted. If two port nodes are highlighted, this command
connects them.  If a patch of material is highlighted, this
option takes a new LAYERNAME for the material.  If a "port"
object is highlighted, this option takes an ARCNAME and an
indicator (yes or no) as to whether this port can connect to
the arc.  The "port" objects may also have their port-angle
and port-angle-range field changed to indicate the
directionality of the port.  The ANGLE field is from 0 to 359
degrees, counter-clockwise from rightward.  The RANGE field is
from 0 to 180 degrees, indicating a spread in either direction
from the port angle.  Finally, if a piece of text is highlighted
that gives information about a layer, arc, node, or the
technology, the change option allows you to change the value
of this text, dependent on the nature of the message.

The option "edit-node" selects a primitive node in the technology
that you wish to edit.  All primitive nodes are represented as
facets with the name "node-" prepended to the primitive name.

The option "edit-arc" selects an arc in the technology that you
wish to edit.  All arcs are represented as facets with the name
"arc-" prepended to the arc name.

The option "edit-layer" selects a layer in the technology that
you wish to edit.  All layers are represented as facets with the
name "layer-" prepended to the layer name.

The option "edit-subsequent" edits the next layer, arc, or node
in the technology (depending on what is currently being edited).

The option "edit-colors" allows you to mix the five overlappable
colors.  It is necessary that five of the layers be given the
color "overlappable" and be given layer letters before color
editing can be done.

The option "edit-design-rules" allows you to edit a listing of
design rule separations in a text editor.  Each line of text
lists a distance and two layer names (thus it is necessary to
have defined the layers before doing this).  If the distance
has the letter "c" in front, then the design rule concerns
electrically connected layers.

The option "edit-misc-information" allows you to edit global
factors for the technology.  Currently, this includes the value
of lambda and the full name of the technology.  The miscellaneous
information is stored in a facet named "factors".

The option "identify-layers" generates a graphical annotation
of the current node or arc, pointing out the layers and labeling
them.  This identification is temporary and dissapears when the
window pans or zooms.

The option "identify-ports" generates a graphical annotation of
the current node, pointing out the ports and labeling them.
This identification is temporary and dissapears when the window
pans or zooms.

For information on color maps, use "help map".
To rename a node, arc, or layer, rename its facet, including the
   "node-", "arc-", or "layer-" part.
