that functionality has been there in pcb and gschem for years.... In pcb, when you Renumber(), it creates an annotation file (similar to an ECO file for those familiar with pads). pcb_backannotate will then take that renumber and apply to your schematics. I see a few things missing in the current implementation though. Would be good to have the layout produce a netlist and then have a standalone netlist comparison tool that can produce the annotation file. Then on the gschem side, a better scheme api (can't wait to see what Peter B has in the pipe here) to apply it instead of directly hacking the .sch files (like pcb_backannotate does) would be nice. -Dan _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
