You are right. Default parameters are updated when I change cellname, but if I change, for example, length from 0.35u to 0.45u, and than change callname, the value 0.45u is remain, but I want that it'd update to 3u - the minimum value for high voltage mos. In all PDK it is present. It is greate problem for me. I thought that it is easy to do, but I don't know some things.
