We use Ultiboard Pro printed circuit board layout software, a product of National Instruments. This incredible software is feature rich and allows captured schematic files from many types of layout softwares to be imported directly into the design window.
These files include rats nest and component list and footprints. This allows fast error free PCB layout up to 32 layers with several types of built in design rule detection utilities. These design rules detect and prevent potential problems prior to the boards being produced in the real world.
