How to add prefix to all instances

maven7783
Hi All,I need a SKILL code for adding prefix or suffix to a top-cell and to all its instances.For eg: I have a Top cell ( INV)  and it has subcells called as a instances. INV hierarchy :  INV-> INV_PMOS-> INV_NMOS So, I want to add some prefix/suffix for all the cells in the hierarchy. Ex: myprefix_INV->myprefix_INV_PMOS-> myprefix_INV_NMOS Thanks,Maven.

    Hi Maven

    You can use the following skillscript. It will find all subcells in a top cell and write the cellnames to a file. You can then use solution 11166194 to do the renaming. : )  Save the script as "findcells.il" in your working directory and execute it as follows:

    load "findcells.il"
    CCSwriteCells("myLib" "myTopCell" "myView")

    where "myView" can be either schematic or layout. The cell names will be written to a file named "list_cell".

    procedure( CCSfindAllCells(myLib myTopCell myView)
       prog( (allSubCells topCv allInsts cellList)
          allSubCells=list()
          topCv=dbOpenCellViewByType(myLib myTopCell myView)
          allInsts=topCv~>instances
          foreach( inst allInsts
             unless( member(inst~>cellName allSubCells)
                allSubCells=append1(allSubCells inst~>cellName)
                cellList=CCSfindAllCells(inst~>libName
                    inst~>cellName inst~>viewName)
                if( listp(cellList) then
                   allSubCells=append(allSubCells cellList)             
                ) ;if
             ) ;unless
          ) ;foreach
          return(allSubCells)
       ) ;prog
    ) ;procedure

    procedure( CCSwriteCells(myLib myTopCell myView)
       let( (outPort cellList)
          outPort=outfile("list_cell")
          cellList=CCSfindAllCells(myLib myTopCell myView)
          foreach(cell cellList
             fprintf(outPort "%s\n" cell)
          ) ;foreach
          close(outPort)
          outPort=nil
          printf("List of subcells have been written to file list_cell\n")
       ) ;let
    ) ;procedure

    Hope that this helps you. : )
