Part Number: SN74CB3Q3257

Hi team,

My customer is using the IBIS model for the bus switch "sn74cb3q3257" in the HyperLynx program to simulate the signal integrity of our PCB Layout and for some reason I cannot configure the model as an output. It only can be configured as an input which does not reflect the configuration we have on the board. 

The model_type of the model name "CB3Q3257_IO" & "CB3Q3257_IO_A"  is "Terminator".

How to use this IBIS model to do the simulation in HyperLynx with such topology?
