I don't know if this will help or not, but here goes... I've never used net highlighting in PCB before, but I had a similar problem in an ASIC designed using Cadence's Virtuoso layout editor. I ultimately tracked it down using the "highlight trace" feature of the program, which included the nifty feature (since highlighting millions of traces can take some time) of allowing me to escape out of it partially through the operation, leaving the nets it had traced out highlighted.
With that feature I was able to narrow the short down to a particular corner of the design, and then through brute force (highlight net... ESCAPE!, see if both vdd & gnd were shorted, repeat) narrow things down to the point that I could trace out the highlighted nets manually and see the short. --wpd _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
