In my symbol library, I usually split parts into a functional symbol and an infrastructure symbol (power and ground, and similar), so my implementation of DJ's suggestion would be to have a symbol for the functional pins of the connector, and then another symbol for mounting holes, shell ground, what-have-you. You could even have different infrastructure symbols for different manifestations of the "extra" pins from different manufacturers. If you give all the symbols associated with a particular component the same refdes, the netlister will sort it out. I like having the infrastructure on separate symbols because then I can put all the power (etc) distribution glorp on it's own sheet(s), and it doesn't clutter up the functional schematic. That's obviously a matter of taste and your personal documentation conventions. -dave _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
