hierarchial summary

deep242003

I want to derive hirerchial summary of a layout(instance names and mosaics. dbGetTrueOverlaps() gives the data in form of layers(please correct if I am missing anything).

while dbProduceOverlapIns() has no hierarchial option .

 

Any suggestion or hint willl be of great help.

  • Using a region query is kind of overkill in that case. You could just write a recursive function to do this - there have been many examples of similar things on this forum before. Since you want instance information, something like:

    procedure(MyUntestedLayoutInfo(@optional (cv geGetEditCellView()) (depth 0))
      let((format)
        foreach(inst cv~>instances
          sprintf(format "%%%ds%%s %%s\n" depth)
          printf(format "" inst~>name inst~>cellName)
          MyUntestedLayoutInfo(inst~>master depth+1)
        )
        t
      )
    )

    Needs a bit of work to handle mosaics (and as the function name suggests, I wrote this off the top of my head and didn't test it)

    Hope that helps,

    Regards,

    Andrew.
