I have not used CadStar/Altium. Many years ago I used gschem as the schematic front end for PADS layout and I was able to do some amount of back annotation. Google for pads_backannotate. As far as I know nothing is in place to do the same for CadStar/Altium. I think it largely depends on what the mechanism is for doing that. PADS does it by taking a schematic netlist (produced by gnetlist) and a layout netlist (produced by PADS) and producing an engineering change order (.ECO) file that basically says what has to happen to make one netlist be like the other. So it is used for both forward and backward annotation. Then you use the pads_backannotate script to apply the .ECO file to the gschem schematic. Note that not all features were implemented. Some were and others simply give you instructions telling what you must manually change. It helped that the PADS .ECO file was documented. -Dan _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
