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 Jameel,

    I had a quick play and the label needs to contain the expression to evaluate, something like the following:

            lab=dbCreateLabel(
            pcCellView ;; cellview label appears in
            list("text" "drawing") ;; layer on which label appears
            (0:0) ;; where label appears
            "car(ilInst~>xy)" ;; label text
            "centerCenter" ;; label justification
            "R0" ;; label orientation
            "stick" ;; font
            1.0 ;; height for the label
        )
	lab~>labelType="ILLabel"

    Now, when I set the label to something like "ilInst~>name" the instance names seemed to show just fine (e.g. "I1"), but with the label as "ilInst~>xy" it did not show any value.  I'm not quite sure why, but if the label looked like a list (e.g. the origin point) or something other than a single number or single name, it did not show.  I have not got time to look into this any further, but the above is a partial solution, so if nothing else, perhaps two separate labels could be created, one for the x value and one for the y?

    Regards,

    Lawrence.
