My idea had the concept of "direct" vs "inferred" attributes in gschem. Direct ones are the ones you specify, like device and value. Inferred ones are those which are determined by process of elimination through some external database. Example: If you picked a 4.7K 0603 resistor, the database might infer a manufacturer's part number and vendor. It might even infer the 0603 based on, for example, some min_wattage attribute and a default preference for certain package types. But my idea didn't *require* it to get back to gschem. The gsch2pcb process would query the database (you can read this as "bom" if you like ;) to find out footprint and pin mapping data for everything it's importing. The schematic doesn't need to know the footprint, pcb does. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
