Support for Orthogonal WSP Grid
While creating a pin, the orthogonal width spacing pattern (WSP) grid constraint defined in the technology file automatically adjusts the pin with a variable extension value so that the start and end points of a pin are on the grid.
The constraint group is specified in the technology file as follows:
constraintGroups(
;( group [override] [definition] [operator] )
;( ----- ---------- ------------ ---------- )
( "orthogonalWSPGridCG" nil nil 'and
spacings(
( orthogonalWSPGrid "Metal1" "M2WSP" )
( orthogonalWSPGrid "Metal2" "M5WSP" )
( orthogonalWSPGrid "Metal3" "M4WSP" )
) ;spacings
) ;orthogonalWSPGridCG
) ;constraintGroups
If the orthogonal WSP grid constraints are part of a specific constraint group, you can select the constraint group from the Default Wire Constraint Group field in the Wire Editing section of the Layout Editor Options form.
