Description
(ICADVM20.1 Only) Creates a widthSpacingSnapPatternDef object in the specified cellview.
Arguments
|
d_cellviewId
|
ID of the cellview in which the widthSpacingSnapPatternDef object is created.
|
|
t_name
|
Name of the widthSpacingSnapPatternDef object.
|
|
(tx_layer [tx_purpose])
|
The layer-purpose pair.
|
|
t_direction
|
The pattern direction. Valid values are horizontal and vertical.
|
|
g_period
|
The spacing between the coarse-grain period tracks (heart-beat period).
|
|
t_defaultActivePattern
|
The pattern used in the areas in which no regions have been drawn.
|
|
l_snappingLayers
|
list(l_snappingLayer)
The list of snapping layer definitions, where:
-
l_snappingLayer: list(t_layer [l_purposeList])
The snapping layer definition, where:-
t_layer
The name of the snapping layer.
-
l_purposeList: list(t_purpose)
The list of purpose names.
|
|
g_offset
|
The distance from the nearest period track to the anchor reference (either the lower edge of the PRBoundary or the origin axis). Default value is 0.
|
|
l_patternNames
|
list(t_patternName)
The list of the allowed width spacing pattern names.
|
|
l_patternGroupNames
|
list(t_patternGroupName)
The list of the allowed width spacing pattern group names.
|
|
g_gridType
|
The WSP grid to use for line-ends. The following values are valid:
-
upperLower: Applies to both ends of the wires. -
lower: Applies to the lower line-ends of vertical wires and the left line-ends of horizontal wires. -
upper: Applies to the upper line-ends of vertical wires and the right line-ends of horizontal wires. -
nil: The default value, which is used when this argument is not specified. In this case, the line-end grid is not configured for the widthSpacingSnapPatternDef object.
|
Value Returned
|
d_widthSpacingSnapPatternDefId
|
|
|
The ID of the widthSpacingSnapPatternDef object that was created.
|
|
nil
|
The widthSpacingSnapPatternDef object was not created.
|
Example
Creates a widthSpacingSnapPatternDef object wsspDef defined by the layer-purpose pair layer1-purpose1 in the vertical direction with space 0.2 and offset 0.1.
