Yes, but isn't that what a netlist test is doing as well...comparing where the data
say's a trace is supposed to be against the actual board itself (ET)...comparing how
wide a space, or thick a trace is supposed to be against the board itself (AOI).

Now in both of these the goal is to verify the product meets requirements.... So....to
stir things up again (it's Saturday, 6:00 AM and I'm feeling the need I supposse
~grin~) as long as I ensure I meet customer requirements, what difference does it make
whether I use our bed-of-nails, flying probe, AOI, enhanced visual, etc...as long as
the board meets the need of the customer?
