Do either gschem or pcb need to know that? We think of a project as being controlled by two files: the schematics, and the board. Why not three? Schematics, board, BOM. Does pcb really need to know the vendor part number? Does gschem? All gschem needs to know is, for example, "2-in NAND", and all PCB needs to know is that pin 7 of U2, a TSOP-32, needs to be connected to ... etc. Knowing which combinations of light symbol and light footprint, and the pin mappings thereof, correspond to physical purchasable parts, can be the job of the BOM. > its not just that. You'd need to maintain a list that deals with > part number differences, pinout differences, etc. I've documented an example of such a database, including the pin mapping problem. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
