was putting in my physical and electrical constraints on a very simple board...
I performed an autoroute (the non-spectra one) within PCB editor, and it routed to completion but I
didn't like some of the results of the constraints, so I deleted all vias, and
then connected lines. I tagged and deleted (like I did for 15 years on MG
looks ok, and no traces on the board - status says 0% routed. However now when
I run the autorouter, if flashes busy for 1/3 od second and then that's it, no warning no errors,
and this is the problem - no routes or fan outs.
saw some older posts about a "done" or "completion flag"
but I can't seem to see where that applies to 16.5.
Do you mind either posting up the brd file or sending a private email with an attachment for help? It's probably something simple but can't help without taking a peek.
