You could create a special S08 footprint with the pins numbered to match the symbol, rather than have a symbol that's numbered to match the generic footprint. > - So-called "don't care" pins and pads, e.g. mounting pads for SMD > connectors. I name them "M1" through "M4" for example, and if you want to connect them to something, yeah, they need to be in the netlist. I'm not sure if DRC ignores them if they don't *have* a name, though. > - Pure holes (e.g. for plastic positioning nubs of SMD connectors): > these often fail DRC check when too close to copper surfaces (e.g. > mouting pads) -- probably because mounting holes are genarally used > with metal screws. DRC doesn't know about screws, it only knows its rules, and even pure holes should obey them or they might short. > Am I correct in surmising that gEDA currently only accomodates type 1? #2 can be done just by giving all the "same" pin the same name/number. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
