Colby, Brad,
Yesterday late in the afternoon, Michelle at Protel Tech support
helped me out with that problem.
As a newbie to Protel, (or any other program for that matter), I usually
keep the default settings if they look right. In the rules section under
clearance constraint I overlooked the setting on which net the rule applied
to, and I had it set on "any net". I thought that was ok. I was wrong; the
any net option will light up a DRC clearance constraint between a pad and a
trace of the SAME net.
When I set that rule to "different nets", about 90% of all my DRC errors
were gone leaving me with real DRC violations. Now, if I were to have turned
off the clearance constraint like somebody mentioned, I would not have seen
the real errors and I would have had a useless board.
Kind regards to all,
Bryan Bernesi
