Change missing via definition (from M6VTMT-->M5VTMT)

mattab

I have  to copy a  database with metal stack ( M1~M6 ,MT)  ---> another database with metal stack( M1~M5 ,MT)  .But when I do this I get a missing via definition(crossmark) of  M6VTMT,

-Is there any way to convert this missing via definition to  M5VTMT

-I understand  M6VTMT definition doesn't exist in  metal stack( M1~M5 ,MT),Is there any way to temporarily copy this via definition into this metal stack and update it to  M5VTMT

 

Thanks

    Hi Mattab,

    You should be able to use the code in this article: How can I replace a given standard via with another standard Via or a custom via (cdsVia) through out my design, while maintaining the via parameters?

    Then do:

    cv=geGetEditCellView()
    foreach(viaHeader cv~>viaHeaders
      when(viaHeader~>viaDefName=="M6VTMT"
        foreach(via viaHeader~>vias
           CCSReplaceStdVia(via "M5VTMT" cv)
        )
      )
    )
