ComputerVision or say Daisy that actually left shorts in
th eboard after autorouted
and that was on a benchmark board.

i think Lloyd's assessment here is pretty spot on
the router prefers an empty board, depending on your level of fussiness
it may not be suitable for your work

In my experience the autorouter works well when starting from scratch 2 or 4
layer boards. You have to get the design rules right for the density you are
hoping to accomplish.
I have not had good luck invoking the auto-router to just route a few new
added parts to an existing high density design.

Are you starting the board 75% routed? If so, be sure all tracks are
correctly assigned to nets before autorouting and be sure to lock preroutes
if you do not want them altered.
Of course 'locking preroutes' may not give the autorouter enough 'room' to
put in remaining tracks, which leads to sh

I've previously used the autorouter on a 6/6 4 layer board with out many
problems. When using the autorouter I've always had to spend a lot of time
cleaning up the routes. Since that time, I've stopped using the autorouter.
After I saw how much better I can do by hand, with a little more effort t
I have never had the autorouter work for me on anything more than a very
basic 2 sided pcb. Even then, I don't like what it does. I do everything
manually. Perhaps I need some training on how to run it properly

Hi,
I've been monitoring this group for a few months now. An associate has a job
to make some changes to his customer's board, and the customer is using Protel
99SE SP6. Since he's not yet joined the group, he wanted me to post this for
him:
We're still hammering away at a 6-layer board w
