Saw an ad in EE Times that might be of interest to some on this list: www.freeautorouting.com -- do the placement with the ratsnet (netlist) and send it to them; they run the Specctra autorouter over it. That's a pretty expensive piece of software. You get back an email that tells you where to retrieve the output. The ad says "you don't have to be our customer to use this free service". Neat. I don't know anything further -- haven't tried it, haven't dealt with that company (PCBnet) before. But if some of you have a PCB layout to be done that's big enough to be a pain to do manually, you might want to check this out. paul
