> Have you actually tried the Eagle auto router? Yes, and I have used a lot of different autorouters in many different PCB programs. Some of them do really stupid things and most ignore the obvious, even when you manipulate the ruleset over and over. All of them will route a low density board to 100%. But the best ones make something that looks good, use fewer vias, and have fewer "last-minute" traces that go all over the board for a half an inch pin pair. With the system I use now, I have two autorouters at my disposal, and SPECCTRA always wins. But going back to my earlier post, I have a lot of respect for Eagle and don't hesitate to recommend it. I won't say that for any other package, including PADS, mostly because of what I perceive as a "lack of value" in the high priced ones and lack of quality or essential(to me) features in the cheaper ones.
