Abstract

We demonstrate an algorithm for interconnect modeling in the presence of process variation based on extension of the truncated balanced realization model reduction algorithm to multi-dimensional, parameter varying systems. Our scheme, based on a set of estimators of the variational TBR projection spaces, is simple to implement, contains embedded error estimators, and leads to nearly optimally sized models.
