I am creating a custom pcell, through the graphical layout method. The custom pcell layout contains an instance of a pdk pcell. I have inherited a parameter 'width' among others from the pdk pcell to my custom pcell. In my custom pcell, I need to repeat contacts based on the value of width. But, it is not possible to use parameter 'width' in repetition expressions. The software gets confused, and assigns 'width' as a new parameter.
Do you know how to reference the inherited 'width' parameter in my custom pcell, without confusing the software? Any responses are appreciated.
