Mike,
Yup it does in fact follow the rules a novel
concept eh? I still can't get used to the fact
you can actualy put shorts the board with
great ease in most systems including Protel.
I know guys that are using
the Expedition autorouter to REALLY do
edge coupled Diff Pairs on some pretty darn heavey
boards and the router is doing it. Shame about the netlist.
Yeah Mentor bought them just when VeriBest
was ready to offer the router as a standalone.
Yes that is the way it should be really, more flexability.
However I have a bone to pick about the way Cadence
did not make the interfaces to both Allegro and Specctra
more similar, whichever was better. Well good luck,
I really had high hopes when I originally heard about
this next gen of Protel, but the more I hear the more that
hope is fading. I do need to really look at the demo yet though
just need the time, should have some pretty soon though.
Bob Wolfe.
