I've been attempting to autoroute my .brd file using freerouter after creating the .sch and .brd files in cadsoft eagle.
I noticed that after creating the DSN file using the following .ulp file eagle2freerouter.ulp which I downloaded from the official Cadsoft downloads page. (http://www.cadsoftusa.com/downloads/ulps/) and then autorouting the DSN file in freerouter I noticed the ground pins seem not to be routed. I'm sure when using eagle autorouter the component ground pins get routed. All my ground pins as per my .brd file in eagle are connected with airwires which I expect to be routed in freerouter as the way eagle autorouter does it.
After posting my question on several forums online I came across an updated version of the ULP file which I've attached. As per the answer to my question (see this for forum link) it could be that I was using an old ULP file but even after using the updated file the GND pins on the DSN seem NOT to get routed.
Any ideas why or is the way freerouter performs its routing? Could it be an oversight on my part in terms of not understanding how freerouter performs routing?
I really would like to stick to using freerouter for my autorouting as it much better than eagle's default autorouter.
