This paper proposes a novel framework for power integrity verification of multicore systems, including voltage stabilization provided by multiple integrated voltage regulators at the core interfaces. The proposed framework adopts a two-stage macromodeling strategy to derive a compact representation of the full system dynamics as observed from each core. These dynamics are parameterized by the time-varying duty cycle provided by dedicated feedback controllers to each voltage regulator, here implemented through an averaged model. We show that the proposed simulation framework has the potential to outperform direct transient analysis based on SPICE engines.

Abstract

This paper proposes a novel framework for power integrity verification of multicore systems, including voltage stabilization provided by multiple integrated voltage regulators at the core interfaces. The proposed framework adopts a two-stage macromodeling strategy to derive a compact representation of the full system dynamics as observed from each core. These dynamics are parameterized by the time-varying duty cycle provided by dedicated feedback controllers to each voltage regulator, here implemented through an averaged model. We show that the proposed simulation framework has the potential to outperform direct transient analysis based on SPICE engines.
