IBIS Model Missing Differential Pair Description RT685

[mkoven1226]

I'm trying to run Hyperlynx simulations using the IBIS model provided by NXP for the RT685- FOWLP249 and there are no differential pairs defined in the files. Balls U2 and T1 should be USB0_DP and USB0_DM respectively, but these are defined as "NC" in the IBIS file, which causes the simulation to fail. Does anyone have experience with changing these to diff pairs? Here's a cut and paste from the IBIS file:

U2 USB0_DP NC 0.49555 2.721e-09 6.162e-13

T1 USB0_DM NC 0.50751 2.703e-09 6.205e-13

Also looking to see if there is a possibility to run aggressor simulations on this USB pair with either a working IBIS model for this part or a similar part.
