How to search for vias with rows or columsn property in layout XL

pham777

Hi,

I am using IC615.06.15.151. In virtuoso layout XL, I opened a Find/Replace form, search for via in current cellview with

via definition == M5_M4

property Name CutRows == 2

But can not find any , eventhough there are  a lot of vias like that in layout. Do I make any mistakes ??

Thanks,

ha

  • There's a mistake in Ted's code - you can't do ~>cutRows on a viaHeader object. You can do that on a via instance, but not a viaHeader. So instead you'd need to do:

    ; take car, because there should only be one match
    viaHeaders = car(setof( vh deGetCellView()~>viaHeaders
                                      vh~>viaDefName == "M5_M4"  && cadr(assoc("cutRows" vh~>overrideParams)) == 2 ))
    viaInstances = viaHeaders~>vias
    foreach(via viaInstances geSelectFig(via))

    This will select the vias afterwards.

    I think you should also contact customer support to request that you can specify cutRows/cutColumns etc in the search criteria for finding vias on the Find command (it doesn't work, because it's not a "property").

    Kind Regards,

    Andrew.
