I've watched engineers using high priced industrial CAD tools take
lots of time for this (so much that it's often contracted out).
On the other hand, I found the process with Eagle CAD to be both very
painless and very quick. Once I had the program for laying down the
SMD pad pattern, I could create a complete library entry for a 120-pin
ASIC in just an hour or so.
