摘要

在本文中,我们提出了一种新的动态功率估计方法,在相当快的运行时间内产生准确的功率测量。该方法使用了一种增强的开关级仿真算法,该算法同时考虑了短路功率和电荷共享功率效应。在针对流行的商用功率模拟工具的基准测试中,我们的方法产生的功率测量平均在商用解决方案的3%以内,同时减少了15到20倍的CPU时间。

Fast power loss calculation for digital static CMOS circuits
In this paper we present a new dynamic power estimation method that produces accurate power measures at considerably faster run times. The approach uses an enhanced switch-level simulation algorithm that takes into account both short-circuit power and charge-sharing power effects. In benchmarks against a popular commercial power simulation tool, our approach yields power measurements on average within 3% of the commercial solution, while taking between 15 to 20 times less CPU time.
