If you display a schematic with a "stack" of instances, it is implied and a good meaning to standardize on, that each instance is identical in every way including attributes attached all the same list, (except for the reference number - the refdes or instance ID), else instantiate them non-stacked and make the separate ones different. Does that open up anything you were thinking of? That's how I'd prefer things...like chip design tools...even if we can't scale up to 100M transistors with gschem or PCB....yet :-) John Griessen -- Ecosensory Austin TX _______________________________________________ geda-dev mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-dev
