Accurate I/O Models for High Speed Digital Design Using Spice Controlled Sources

Abstract

For useful signal integrity analysis, availability of timely and accurate silicon models is extremely important. Nonlinear voltage controlled current sources (vccs), current controlled voltage sources (ccvs), voltage controlled voltage sources (vcvs) and current controlled current sources (cccs), available in Spice can be used in describing these device models. With this approach, one can represent the macro- models of driver, receiver, load and termination using basic controlled sources as Spice primitives, without revealing process related proprietary information.
