[PCell] How do I Create a Label through script/coding in a pcell?

All you need should be a call to the dbCreateLabel API.

Hey, I already tried that and the label really does appear in the original Pcell. But when I try to place the Pcell in a layout, the Rectangle is there, but the label is not. So I thought, that you need a ROD-Function for that. Did I do something wrong here?


pcDefinePCell(
    
    list(ddGetObj("ex") "Label_Test" "layout")
    (
        (Label t)

    )
    let( ()

    dbCreateLabel(dbOpenCellViewByType("ex" "Label_Test" "layout") list("MET1" "pin") 1:1 "MyLabel" "centerCenter" "R0" "stick" 0.3)

    )

    let( ()
        rodCreateRect(
            ?layer list("MET1" "drawing")
            ?bBox list( 0:0 1:1 )

        )
    )
)

You're creating the label in the wrong cellView. By re-opening the cellView with dbOpenCellViewByType, you're creating the label in the superMaster rather than the subMaster for this variant. Instead use pcCellView to specify the cellView for the current variant:

    dbCreateLabel(pcCellView list("MET1" "pin") 1:1 "MyLabel" "centerCenter" "R0" "stick" 0.3)

I'm also not sure why you're surrounding each statement with an empty let? That's not necessary.

Thank you so much Andrew! It works!
