Electrical characterization of S/390 MCM packages from S-parameter measurements below 3 GHz

Abstract

In this work, we investigate the electrical performance of critical signal paths in IBM S/390 MCM packages. We present lumped RLC-models suitable for standard circuit simulators operating in the time domain, e.g. SPICE. The models are developed from finite element simulations of typical signal path segments. By comparing S-parameters from simulations of the models to two-port network analyzer measurements, we validate the models in a frequency range up to 3 GHz.
