摘要: Fast and accurate power estimation has become an important topic with the increasing need for low power electronics. In this paper we address the problem of using event-driven simulation tools for power estimation. We identify and compare two approaches: input-driven and output-driven, and propose several ways of improvement. The estimation accuracy is degraded in event-driven power estimators due to superfluous and partial glitches. We described glitch filtering and estimation techniques pertaining to input-driven and output-driven power estimators. An output-driven power estimator, Peony, was developed which used the proposed path pouter idea to improve the estimation accuracy. It achieved significant power estimation accuracy improvement at a speed of two orders of magnitude faster than Spice.
