My experience with the Protel autorouter is with Advanced Route 3.1 (Protel 2.8, 3.X) and the integrated router in 99se. Don't know about 98 and DXP.
>From what I have seen, both AR 3.1 and AR 99SE can quickly produce 100% results which are acceptable on low to medium-speed digital boards, if the routing rules are tweaked just right. It takes quite a bit of experimentation to discover the magic rule set to achieve this. I have run the same board as much as 25 times, tweaking the rules a little each time, to get acceptable results. Fortunately, this is usually feasible since the router is so fast. All I can think of is that maybe you should tweak the routing rules to improve the results. It's the "cut-and-try" method. Laurie, that's an "interesting" website you have there ;-) Best regards, Ivan Baggett Bagotronix Inc. website: www.bagotronix.com ----- Original Message ----- From: "Laurie Biddulph" <[EMAIL PROTECTED]> To: "Protel EDA Forum" <[EMAIL PROTECTED]> Sent: Tuesday, October 28, 2003 1:45 PM Subject: [PEDA] Stock Components/Joining nets - now autorouting Thanx everyone for their responses to my queries which were what I expected would be the answer. On another topic. We have a 4-layer board (nothing unusual mix of analog and digital components) which routes on Protel 98 in around 15-30 minutes and always achieves 100% routing. If we run the SAME artwork in Protel 99SE it takes over 7 hours and only achieves around 90-95% completion. Protel DXP is taking around 5 hours and again only 90-95% done. Does anyone have an explanation as to why the newer packages are having such a hard time? Are we missing some `setup' trick that allows these versions to run as well as Protel 98? I could understand a longer runtime (say 2-5 hours) if we finished with 100% routing and a `good' route (as opposed to one that needs cleaning up like Protel 98 usually gives) but so far the results are VERY poor. I am running on a Pentium 4 with 256MB RAM and a 1GHz processor so don't see that the machine is the problem.
