Supply voltage emulation platform for DVFS voltage drop compensation explorations
Andreas Genser, Christian Bachmann, Christian Steger, Reinhold Weiß, Josef Haid · 2011
The supply voltage level has emerged as an important metric alongside power consumption information to investigate system stability and reliability issues. In this paper, we propose a supply voltage emulation platform based on a power emulation approach to derive real-time power and supply voltage information from a system. Moreover, we present a dynamic voltage and frequency scaling (DVFS) based voltage drop compensation scheme to maintain stable system operation. The early design phase applicability of our emulation-based approach enables the investigation of the effectiveness of voltage drop compensation schemes before the final chip is available.
