SKILL examples to modify Virtuoso label text on schematic & layout

archive

So others benefit...

Here is a simple SKILL code example for modifying label text in Virtuoso schematic or layout based on a thread from comp.cad.cadence thanks to our good friend Bernd Fischer...

procedure(MyReplaceLabels( libName viewName "tt" )
        let( ( d_libId d_cvId l_cellList l_labelList )

d_libId = ddGetObj( libName )
l_cellList = setof(
                d_cell d_libId~>cells
                member( viewName d_cell~>views~>name )
                )

foreach( d_cell l_cellList

     d_cvId = dbOpenCellViewByType( libName d_cell~>name viewName nil "a" )        

     l_labelList = setof( d_shape d_cvId~>shapes  d_shape~>objType == "label" )

     foreach( d_label l_labelList
        case( d_label~>theLabel
                        ( "VDD"
                                d_label~>theLabel = "vdd!"

                        )
                        ( "VSS"
                                d_label~>theLabel = "gnd!"
                        )
                ) ;; close case
     )

   dbSave( d_cvId )
   dbClose( d_cvId )
)

)

)
;; End of MyReplaceLabels.il

    This SKILL code example from Cadence solution #11094824 will convert symbolic
    pin angle brackets "< >" text to square brackets "[ ]" in a Virtuoso layout.

    Specifically, this sample SKILL code replaces all labels starting with  "A" 
    and ending with ">" to have delimiters replaced  with "[ ]".

    Please note this sample SKILL changes ONLY the labels and does not modify the 
    connectivity information on a pin that may have been created using the 
    original label.

    This sample SKILL code passed a Virtuoso CIW: Tools -> SKILL -> Survey prior to 
    posting.
