Rename label and part of instance in multiple layouts

AnuJoamon

I have many layout cells in my library in which I need to do two changes

  1. I want to replace label xxxABxxx with xxxCDxxx (in a specific layer say "m1" "dg")
  2. Replace instance yyyAByyy from library YYYY to instance zzzCDzzz from library ZZZZ.
  3. Check that there is no instance in the entire library coming either from the same library of one reference library (specified).

Anuj.

    Thanks Derek. The examples provided by you have provided me clarity to proceed. But I am having some syntax problem while using the foreach ...

    procedure(checkWireCell(libname wireCellList)
        let((outfNameError outfError error libid cellList cellId cell cv inst)
       libid=ddGetObj(libname)
       foreach(cell wireCellList
          if(member("layout" dbAllCellViews(libid cell~>name)) then
              cv=dbOpenCellViewByType(libname cell~>name "layout" nil "r")
              if(length(cv~>instances)!=0
                  foreach(inst cv~>instances
                       if((inst~>libName!=libname && inst~>libName!="ALL_PARTS" ) then
                        fprintf(outfError "\nWARNING: INSTANCE  %s  Of Cell %s points to a different Library  (%s)" inst~>cellName cell~>name inst~>libName)
                        error = 1
                         )  ; if
                    )  ; foreach
                 ) ; if
              dbClose(cv)
          else
              fprintf(outfError "\nWARNING: Cell %s does not contain a layout view" cell~>name)
                           error = 1
          )
       )
     ) ; let
    ) ; proc
