It does not have to be a $xxxxx per seat CAD package. My engineering
drawings are done on a CAD that cost me just under $1k and can also do

Autorouting invariably stinks. They have give-away packages from companies now that do auto-routing. Not ONE of them matches a good layout man. Most generate so much noise in the routing that you have your uC making mistakes in low power high speed applications.
