Amazing! Very, very exciting work. I have a very small, mixed through-hole and smt design that I'd be happy to throw at you. About 70 components, the board is pretty sparse at 4"x1.8"--- but a much denser version is in the works. :) Due to connector placements, the board has some power and signal paths that must cross--- with the power traces getting priority because I want them to be as short as possible. I hand-route the power traces, as well as the power supplies to the ICs, and then tell the autorouter to route the rest with the "signal" trace style. I also hand-route a GND trace around the perimeter of the board, both to make sure that the board's mounting holes have good grounds, and to help mitigate ESD concerns as the board must be frequently handled. (It probably doesn't help much, but it makes me feel a little better). The autorouter (geda-gschem-1.4.3-2b1 deb package) is unable to route the remaining rats using only "power"-sized traces, but does a decent job if I use "signal" ones. When it has problems, it's almost always because a previous trace boxed it into a corner--- usually because it ran two traces in parallel on the top and bottom layers, or by putting traces too close to pins. The autorouter also has this annoying tendency to run a really long GND trace somewhere other than the GND trace I laid down 10mil away in the other direction. Odd. Anyway, let me know the best way to get this file to you, both the version I'm having built now and unrouted ones that you can play with. And whatever else you'd like. b.g. -- Bill Gatliff b...@billgatliff.com _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
