I now realise why autorouters are so popular in PCB layout software. Sure an autorouter is pretty dumb and won't do much for optimising track layout to get the lowest EMI, BUT routing by hand is like a massive puzzle, especially when you're trying to do it with only 1 layer. I'm using freepcb which can use an external autorouter, but it insists you use a 2 layer board to give the algorithm less headache. Can anyone here can recommend something, free or not. I hope to avoid Eagle - but may be that's the only alternative.
