Novel Method for Modeling IBIS4.2 Four-Level Hysteresis Behavior in an Analog Simulator

IBIS4.2 (I/O Buffer Information Specification) standard describes the hysteresis behavior from one simulation point to the other. In an analog simulator, solution is obtained based on multiple iterations in between simulation points. These iterations can lead to undesired behavior. The common problem that might be encountered with this specific behavior in an analog simulator due to iterations will be discussed, and a novel way for implementation that overcomes this problem will be proposed.
