Find all libraries used in design hierarchy

MorrisDH

Trying to generate a list of all libraries that are used in a design hierarchy.

This code does not work:

procedure( getLibsUsed(libName cellName viewName libList)
 let( (cvId)
    printf("Finding libraries used in %s\n" cellName)
    cvId=dbOpenCellViewByType( libName cellName viewName "" "r")
    foreach(master cvId~>instanceMasters
      unless(!master || member(master~>libName libList) || master~>superMaster
        libList = cons(master~>libName libList)
        getLibsUsed(master~>libName master~>cellName master~>viewName libList)
      ) ; unless
    ) ; foreach
    println(libList)
  ) ; let
) ; procedure

The last print statement from the above list only library name of two instances at the top level.

  • Because the cons is a non-destructive operator, I would change this by having your function pass back the libList it builds. So for example (and I didn't test this):

    procedure( getLibsUsed(libName cellName viewName libList)
     let( (cvId)
        printf("Finding libraries used in %s\n" cellName)
        cvId=dbOpenCellViewByType( libName cellName viewName "" "r")
        foreach(master cvId~>instanceMasters
          unless(!master || member(master~>libName libList) || master~>superMaster
            libList = cons(master~>libName libList)
            libList = getLibsUsed(master~>libName master~>cellName master~>viewName libList)
          ) ; unless
        ) ; foreach
        ; probably don't want to print at each level - unless for debugging
        ; println(libList)
        libList
      ) ; let
    ) ; procedure
