Macromodeling for Nonlinear Distributed Interconnect Networks

This paper presents an automatic, multidimensional Krylov subspace based approach to developing macromodels for nonlinear distributed interconnect networks. The approach avoids the need for extra ports due to nonlinear elements by introducing constraint equations to link the nonlinear and linear portions of the network. Numerical examples have been included to demonstrate the efficiency of the presented algorithm with respect to two metrics: computational cost and the size of the system that will be simulated.
