When dealing with a match group in Allegro XL, it counts the length of the thru-hole barrel from the inner layer (where the trace connects to the barrel) to the outer surface of the PCB (component mounting side). Normally this is a good thing to do because it makes the estimated "signal path length" more accurate.
However, when using press fit connectors, the "compliant pin" makes contact somewhere in the middle of the barrel (40 to 60 mil down), not on the outer surface. So a trace touching the barrel on an inner layer actually has less delay than a trace touching the barrel on the top layer. Thus the estimated length Allegro XL computes is wrong. It may only be wrong by 5-8 ps, but when your skew budget is only 20 ps total, I can't give up 8ps error at the connector.
Any advice for dealing with this?
