How to access pcell instance co-ordinates from within Pcell code.

Jameel
Hi, Is there a way to find out the co-ordinates of the pcell instance from within the pcell code? Say for example, I want to create a pcell that prints a label showing the co-ordinates of the where the pcell is placed. within the code of the pcell I can create the label at the origin but i need to know the co-ordinates of the pcell instance in order to print the label. One way of doing this would be to pass the co-ordinate of the pcell instance as parameters, but am not sure if this is the correct way to do it. Thanks, -Jameel

    Hi  Lawrence, Derek,

    Below is a simple pcell that I built  using your input. When I load it up I get this error - *Error* eval: unbound variable - ilInst

    Do you know what's wrong?

    Thanks,

    pcDefinePCell(
    ; Identify the target cellview.
        list(ddGetObj("test") "PCELL_TEST" "layout")
        ; Declare formal parameter name-value pairs.
        (
            (layer "RDL") ;;
        )
        let(() ;; Define the contents of the cellview.
            dbCreateLabel(
                pcCellView ;; cellview label appears in
                list("TEXT" "drawing") ;; layer on which label appears
                (0:0) ;; where label appears
                sprintf(nil "special point = %P" ilInst~>xy) ;; label text
                "centerCenter" ;; label justification
                "R0" ;; label orientation
                "stick" ;; font
                10.0 ;; height for the label
            )
        ) ;; let
    ) ;; pcDefinePCell
