This paper presents a model order reduction approach, specifically designed for the generation of compact and efficient transient simulation models of system-level power distribution networks (PDN) of multicore processor systems. The proposed approach applies a Krylov subspace projection, with a structure that is adapted to a block-coupled state-space description of individual PDN subsystems. The latter include board-package, averaged models of integrated voltage regulators switching circuitry, and individual models of all cores including regulator inductors and capacitors. Numerical results from pro-posed reduced-order models provide major speedup with respect to SPICE with negligible loss of accuracy.

Abstract

This paper presents a model order reduction approach, specifically designed for the generation of compact and efficient transient simulation models of system-level power distribution networks (PDN) of multicore processor systems. The proposed approach applies a Krylov subspace projection, with a structure that is adapted to a block-coupled state-space description of individual PDN subsystems. The latter include board-package, averaged models of integrated voltage regulators switching circuitry, and individual models of all cores including regulator inductors and capacitors. Numerical results from pro-posed reduced-order models provide major speedup with respect to SPICE with negligible loss of accuracy.
