That works. You just have to be careful about attributes like footprint: gnetlist will grab the first one it sees and ignore any others. You can also use my pins2gsch script and just do pwr/gnd as a table, no drawing needed. > But I wondered about netlisting and refdes support. Bummer that > renumbering doesn't preserve relationships. There are several renumbering scripts about, all with different capabilities/weaknesses. Everybody expects renumbering to read *their* mind ;-) > > Kai-Martin Knaak wrote: >> On Wed, 14 Oct 2009 15:58:14 -0700, Stephen Williams wrote: >> >>> I'm planing a circuit where some chips have a wide variety of >>> different >>> power supply requirements.
