rodCreateRect subRectArray loop

psill000

I am creating a stdcell pcell base layer cell and I am using the rodCreateRect function.

Is it possible to create a loop for the subRectArray so I can create a double or triple high stdcell without write another procedure. single high works as I want.

double high example of layers to stack

    Hi Paul,

    I don't think this is possible with rodCreateRect(). Alternatively you might use rodCreatePath() with the ?subRect argument. That lets you define any number of sub pathes - here's an example:

    (rodCreatePath ?cvId cv ?layer "metal1" ?pts (list 0:0 0:12)
         ?subRect (list
             (list ?layer "via1")
             (list ?layer "via2")
         )
    )

    I can do multiple subRect also, but I was looking for a way to create a loop of the different layers for a two or more high stdcell.

    Example:

    ?subRect list(
                list(?layer "lpp1")

                list(?layer "lpp2")

                list(?layer "lpp3")

                list(?layer "lpp3")

                list(?layer "lpp2")

                list(?layer "lpp1")

           )

    well you could use "foreach mapcar" to get the list of sublists required for ?subRectArray:

    ?subRectArray (foreach   mapcar   layer   '("metal1" "metal2" "metal3")     (list '?layer layer))

    Is this what you were looking for?
