See: http://pcb.sourceforge.net/pcb-20080202/pcb.html#Renumber%20Action that appeared in the snapshot from the summer of 2006. and october of 2006, this appeared: http://git.gpleda.org/?p=gaf.git;a=blob;f=utils/scripts/pcb_backannotate;hb=4233fc6baa24a17655a312f47d14a53204a00057 hope that link pastes ok. It would not be hard to teach Renumber() other algorithms for how the renumbering works (vertical vs horizontal preference for example or even nearest neighbor). I didn't include full support for pin or gate swapping in pcb_backannotate, just like pads_backannotate doesn't support that part fully either. The annotation file used to convey the information from pcb to gschem could potentially be used as the conduit for more general forward/backward annotation. I think to be really effective you'd like to have a netlist comparison program so you could write out a schematic netlist, a layout netlist, compare the two and produce an appropriate annotation file. fwiw, this is how PADS works. -dan _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
