I know that lots of people out there feel that autoroute results are not useable.
I find that the autorouter is a good way to get a good placement. I use eagle. I do a basic placement, autoroute everything and look where my wire crossings are. Where I can reduce wire length. ripup, repeat.
The thing is, the eagle router really isn't that good. I often get routes that should be doable with a straight shot, yet eagle insists on adding jogs.
I feel that given a good placement, many routes should be obvious. I don't want to click them all by hand.
So I'm looking for something better. toporouter is intriguing. The problem there is I don't know how to write an output from eagle that it reads.
