OrCAD acquired the program from Massteck to replace their previous
offering, which was even worse. (I got my copy of OrCAD PCB by
converting my Massteck license.) As autorouters go, it's pretty good
(for dome things.) For manual routing, it sux. And I'm sure Cadence
is very proud that they've kept every bug intact, without adding any
Disable routing on everything except power and ground. Restrict power
and ground to the layers you're using. Make golly-darn sure that
plane layers are set up correctly. (Sounds like you're mixing signals
and power on the same layer; to Massteck, this is NOT a plane.)
Then let it auto-route those two nets.
I do pretty much the same thing, but I cheat: I pop it into Pads to
do the power and ground.
You'll have some clean-up to do, but at least it should stop b!tching.
