When I see these rules to match within 10 mils (or n mils) I wonder who
much matching is really required in the electrical sims (or other
assumptions). Because I don't believe that matching physical length is
the same as matching electrical length. And the router only does
physical length. So the question is, "how close is electrical length to
physical length". I would be very suprized if the accuracy can be
expected to be better than the line width (call it 5 mils).
So, if we are just making a "easy to understand" rule. Fine.
But if it is a necessary rule. Not fine.
