There are a couple of nice programs that will check your PCB layout
program's netlist output against the spice net list to find errors. They
use some tricks to relate the net names to each other so that they will
find nets that are broken into two sections and nets that are shorted.
They are free to download and I was going to give you the link but since
you top posted I decided not to.
