Accelerating system-on-chip power analysis using hybrid power estimation

Abstract

Fast and accurate power analysis is a critical requirement for designing power-efficient System-on-Chips (SoCs). Current system-level power analysis tools are incapable of generating power estimates under real-life workloads within an acceptable amount of time, even for moderately complex SoCs. Our work addresses this problem by borrowing on emulation, which is a widely used technique to accelerate functional verification. Unfortunately, hardware emulation of all the necessary functions for full SoC power analysis is likely to be infeasible for most systems, due to constraints on emulation capacity, and the lack of emulation-ready, synthesizable models for some SoC components early in the design process.
