I want to create via on two metal overlaps, and I need to pull back or delete the metal overhang or extensions to via center? Kindly help me, just started on coding.

CDB over 1 year ago

HI all,

I am able to generate vias on two metal overlaps using " (viaGenerateViasFromShapes cv shapes via_opts) "

but I am not able to extend the metal overlaps which are extra, as in auto via you will be having metal extensions with drc clean.

basically I want to stretch the metal overhang on the vias.

Hello
You might want to try the viaRecomputeViasAtPoint

An example of some of the syntax I have used

techId = techGetTechFile(cv)
constrGrpId = cstFindConstraintGroupIn(techId "default")
viaOpt = viaGetViaOptions(constrGrpId)
viaOpt~>automatic~>extendEnclosureBeyondOverlap = t
viaOpt~>automatic~>printStatisticsReport = nil

viaRecomputeViasAtPoint(cv xy viaOpt ?startLevel 0 ?stopLevel 32)
