Using variable for CDF Parameters in a netlist file

meredith

As a work around for pPar, is it possible to use a variable for a parameter in a CDL netlist file and pass the value of that variable down through hierarchy?

    One possibility might be to take a copy of the component into your own library, and then use Tools->CDF->Edit, edit the Base CDF of the copy, and remove the callback for the width and length parameters and change the area to be iPar("width")*iPar("length") - or whatever is an appropriate expression. Then use the copy instead of the original PDK device.

    Not sure if that will upset any flow/design review process you might have though...

    Regards,

    Andrew.
