I like the auto-router in WinQCAD. I usually place chips,
auto-router, move things, re-router, move other things, and so on
until I get the board about where everything will fit.
then I go in an lay out the power lines, and any guard rings or any
other odd feature needed.
I place any important traces and at some point, I run the auto-router
to let it fill in the other stuff.
Then I go back and tweek it as needed. usualy there is a lot needed.
But for the help of the autorouter in the early layout, it would be
much harder to find some very useful layouts.
