How to use coordinate & layer name to find sub cell name and library name from top level layout?

JMTKRex

If I've coordinate, layer name and net name, how to find sub cell name and library name from top level layout?

ex:

M2A       (20.112, 97.430)     avdd

  • Not sure the net name is particularly helpful here, but you could use:

    layerName="M2A"
    coord=list(20.112 97.430)

    procedure(abGetHierPathShape(overlap)
      if(listp(overlap) then
        abGetHierPathShape(cadr(overlap))
      else
        overlap
      )
    )

    overlaps=dbGetTrueOverlaps(cv list(coord coord) layerName 32)
    foreach(overlap overlaps
      containCv=abGetHierPathShape(overlap)~>cellView
      printf("lib: %s cell: %s: view: %s\n" containCv~>libName containCv~>cellName containCv~>viewName)
    )

    There's a loop because there could be multiple cellViews with the layer at that point.

    Regards,
