how to change Pcell param using skill? - Layout

Peter123 over 15 years ago

Hi,

Can anyone tell me how to change the pcell (layout) param using skill?

Eg: If i want to change the Width of the P-mos from 1um to 5 um.. ( change all Pmos in one layout cell).

Hi Peter,
It depends on what type the width parameter is, and what it is called, but if I assume the parameter is called "width" and it is a string parameter, you might do:
listOfPmosInstances~>width="5u"
You could find listOfPmosInstances by doing:
listOfPmosInstances=setof(inst cvId~>instances inst~>cellName=="pmos" && inst~>libName="myPDKlib")
change the "pmos" and "myPDKlib" as appropriate.
Regards,
Andrew.
