Abstract

This paper presents a new algorithm for efficiently combining the process of model-reduction of high-speed interconnect subnetworks with nonlinear simulation. The proposed algorithm guarantees the number of states required during macromodel synthesis from reduced-order frequency-domain matrix-transfer functions to be minimum. Macromodels thus generated are both controllable and observable. In addition, the proposed algorithm can be used in conjunction with any of the existing model-reduction techniques. Examples are presented to demonstrate the efficiency of the proposed algorithm compared to previously published techniques.
