Description
Creates a width spacing pattern in the specified cellview. This function requires you to specify the color for only the first track, referred to as the starting color. All other tracks are colored automatically by shifting colors.
Arguments
|
d_cellView
|
The ID of the cellview for which the width spacing pattern must be created.
|
|
t_name
|
Name of the width spacing pattern.
|
|
l_patternSpecs
|
list(l_patternSpec)
List of track group specifications.
where,
-
l_patternSpec
: list(l_specs [d_repeat [l_wireTypes]
[l_displayPacketNames]])
A track group specification.-
l_specs
: list(l_spec)
List of individual track specifications for the specified track group.-
l_spec
: list(g_width g_space [t_wireType]
[t_displayPacketName])
A track specification.
g_width
Width of the shapes for the specified track.
|
|
|
g_space
The distance of the next track from the current track, in the period direction.
t_wireType
The type of wire. This parameter can be specified only when d_repeat l_wireTypes is not specified. It is used to refer to a specific group of tracks, for example, routing a set of tracks by name. The default value is an empty string "".
t_displayPacketName
The name of a display packet that can be specified to control how the track should be drawn on the screen.
|
|
|
-
d_repeat
The number of times the track group is repeated. A value of 1 creates the track group from the specified l_specs (1x). A value of 2 creates the track group from the specified l_specs that are repeated once (2x).
|
|
|
-
list([t_wireType ...])
List of wire types associated with the specified track group (only if d_repeat is specified on the track group). Use an empty string ("") to specify no wire type for an individual track. If the number of tracks in the track group is greater than the number of wire types in this list, then the wire types list is repeated across the track group until all tracks are assigned a wire type, one-by-one. -
t_wireType
The type of wire.
For example, for a track group with 6 tracks:-
If l_wireTypes is
list("a" "b"), then tracks 1, 3, and 5 are wire type a; tracks 2, 4, and 6 are wire type b. -
If l_wireTypes is
list("a" "a" "b"), then tracks 1, 2, 4, and 5 are wire type a; tracks 3 and 6 are wire type b.
-
l_displayPacketNames
List of display packet names for the track group (only if d_repeat is specified).
Default value: An empty list.
l_displayPacketName: list([t_displaypacketName …])
t_displayPacketName is the display packet name for the specified track.
|
|
t_startingColor
|
Color of the first track. All tracks are automatically colored by color shifting from the previous track color. Valid values are "mask1Color", "mask2Color", "mask3Color", and “grayColor”. Use "grayColor" to make all tracks uncolored.
|
|
n_offset
|
The distance of the first track from the period track.
|
|
g_repeatOffset
|
Determines whether the offset is applied when a pattern repeats.
When set to t the offset is repeated every time and when set to nil the offset is applied only once.
|
|
t_allowedRepeatMode
|
Name of allowed repeat mode. Valid values are "any", "none", "steppedOnly" and "flippedOnly". The default value is "any".
|
|
t_defaultRepeatMode
|
Name of default repeat mode. Valid values are "noRepeat", "stepped", "flippedStartsWithOdd" and "flippedStartsWithEven". The default value is "noRepeat".
|
Value Returned
|
d_widthSpacingPattern
|
The ID of the created width spacing pattern.
|
|
nil
|
Returned in case of failure.
|
Examples
A width spacing pattern wsp is created in the cellview cv with two track specifications.
dbCreateWidthSpacingPatternWithColor(cv "wscp" '((((0.04 0.08 "mywire1" "mask1Color") (0.09 0.012)))) "mask2Color" 0.05 t "steppedOnly" "stepped")
-
For the first track,
-
0.04 is the width of the shapes. -
0.08 is the distance of the next track from the current track, in the period direction. -
mywire1 is the type of wire to use. -
0.05 is the distance of the first track from the period track.
-
For the second track,
-
0.09 is the width of the shapes.
-
0.12 is the distance of the next track from the current track, in the period direction.
-
The starting color is
mask2Color. -
The following figure shows the period when the number of masks on the layer is 2 (
mask1Color and mask2Color).
-
The allowed repeat mode is
steppedOnly, meaning the pattern can only be stepped, but not flipped. -
The default repeat mode is
stepped, which conforms to the allowed repeat mode of steppedOnly.
