Abstract

A method for converting an IBIS (Input/output Buffer Information Specification) model to a SPICE (Simulation Program with Integrated Circuit Emphasis) behavioral model by RC (resistor/capacitor) extraction is provided. In the method, when the SPICE behavioral models of pull-up and pull-down transistors being switching components of the output IBIS model is embodied, a resistance is extracted from voltage-current tables of the pull-up and pull-down transistors and a capacitance is extracted from voltage-time tables of the pull-up and pull-down transistors so that a static characteristic is modeled as a resistor and a dynamic characteristic is modeled as a capacitor.
