I recently started to use Eagle 6.1 and I noticed that when it auto-routes my board it typically generates between 30 and 45 air wires :-( I thought I would give FreeRouting.net a try. They provide a ULP file to generate a DSN file, that is used as input to that site. But the ULP file they provide does not work, reporting a syntax error.
Is there a way to generate a dsn file so I can try out freerouting.net?
Also, are there atrategies for reducing the number of air wires?
Thanks very much!
