Hi, Tina, This depends on what you mean by "levels". If you mean 5 drive strength options, but no change in drive strength option during a transition, then usually one IBIS model is created for each drive strength. If you mean 5 different drive strengths used during one transition (such as a buffer with internal feedback), then table-based IBIS modeling probably would not be suitable. In this case, one could consider IBIS 4.1, with an AMS or SPICE language option. Best regards, Lynne "IBIS training when you need it, where you need it."
