Hi,
I had something very similar a few years ago, and it was caused by a
circular board outline, which the autorouter doesn't like. Have you got
any arcs in your board outline?

stops...

Please respond to
"Protel EDA Forum"
... doesn't crash, just stops:
On a fairly dense PCB, set up for 14 layers (8 signal, 6 power/ground) on a
5/5 design rule, I'm seeing strange router behaviour.
The router happily goes through the SMD fanout, memory & pattern routers
but
part way through the push 'n' shove pass it does a DRC and exits. No
status
report, no error message, no crash - it just stops.
I've double checked that the board is within system capabilities, corrected
a few off-grid components and even re-fanned out four 1152-pin BGAs to make
sure the vias are all on-grid. There are still off-grid pads, but that
sort
of thing hasn't stopped the router on previous designs.
The router seems to be objecting to something, albeit in a slightly more
restrained manner than usual, but the question is what?
Any hints/tips/solutions gratefully received.
(BTW, the Protel version is P99SE/SP6 and the PC is an 800-and-something
MHz
P3 with 512M SDRAM running Windows 2000 Professional)
Regards,
Andy Gulliver
