A fast full-chip static power estimation method

As IC technology advances, leakage current induced static power has become the major obstacle for chip to achieve high performance. Fast estimation of full-chip static power is difficult because static power depends nonlinearly on temperature. In this paper, we propose a new fast full-chip static power estimation method. The new method uses Taylor expansion based approximation to linearize the nonlinear leakage-temperature dependency locally. A new linear thermal model is formulated based on the local linearization for easy full-chip transient simulation of temperature and static power. Experiments show that the new method achieved up to 10× speedup against traditional iteration based method with high estimation accuracy.
