An Efficient Parallel Electromagnetic Solver for Extracting Scattering Parameters from Large Electrical Interconnects With Many Ports

Abstract

An efficient parallel solver is proposed for extracting port parameters from electrical interconnects with many ports. We demonstrate that block iterative methods can be used to improve convergence rate and parallel efficiency. The proposed method is up to $16\times$ faster than an existing method on structures with up to 128 ports and 3 million unknowns.
