Maybe it is important to recognise, that DRC and LVS are completely orthogonal in PCB, and I think that is a good property, that should be kept. DRC (DesignRule Check) does not consider the netlist. It checks the connectivity of all copper, and verifies the rules for connected and not-connected copper. LVS (Layout vs Schematic) checks that the copper connections between pins matches the netlist, without checking for DRC rules. Distinguishing between net and no-net copper will break this separation. This should not be done lightly. -- Stephan _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
