摘　　要：集成电路设计工艺的不断提升在带来更高性能的同时也造成了功耗过高的问题,如何兼顾高性能与低功耗成为当前高性能超大规模集成电路设计需要解决的关键问题,标准单元替换是一种有效的降低功耗的方法。首先比较了2种不同的标准单元替换策略,然后通过实验分析了不同策略的功耗优化效果以及对性能的影响,最后提出了合适的标准单元替换策略来优化功耗。With the continuous improvement of integrated circuit design technology,it has brought about higher power consumption while bringing higher performance.How to balance high performance and low power consumption has become a key issue that needs to be solved in the current high-performance VLSI design.Standard cell replacement is such an effective way to reduce power consumption.This paper compares two different standard cell replacement strategies,and experimentally analyzes their power consumption optimization effect under different strategies and the corresponding impact on performance.A suitable standard cell replacement strategy is proposed to optimize the power consumption.
