Parameterized model order reduction via a two-directional Arnoldi process

This paper presents a multiparameter moment-matching based model order reduction technique for parameterized interconnect networks via a novel two-directional Arnoldi process. It is referred to as a PIMTAP algorithm, which stands for Parameterized Interconnect Macromodeling algorithm via a Two-directional Arnoldi Process. PIMTAP inherits the advantages of previous multiparameter moment-matching algorithms and avoids their shortfalls. It is numerically stable and adaptive, and preserves the passivity of parameterized RLC networks.
