thanks Quek, This seems to generate sub-lib from existing library by removing specific parameters. that's not what I want. we've already had such sub-lib. but when the schematic design updated to attach new lib, the instances in the schematic would keep past parameters, not automatically updated to have only parameters from the new library. so what I want is to remove obsolete parameters from the instances. would there be easy way for that? thanks, David![]()
