Part Number: SN74CB3Q3257
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?

Thank you for being patient, I am still working with our team to get an answer to your question. I will provide an update for you again early next week.
Have a good weekend.
Thanks again for being patient.
I understand that you would like to use the IBIS model to model switch resistance for when the switch is on to check system-level signal integrity. The IBIS model for this device actually does not contain a model of the switch resistance. It only includes terminator models of diodes and capacitance for the switch terminals when they are turned off.
