基于功能仿真的RTL级低功耗优化

RTL Low Power Optimization Based on Functional Simulation

针对复杂集成电路设计中的功耗问题,提出了基于典型功能仿真和代码解析通过逻辑重组、操作隔离、预计算等技术实现寄存器传输级(RTL)低功耗的优化方法,该方法工作在RTL级,只需得到HDL仿真工具的支持。实验结果表明采用文章所提出的优化方法可显著降低电路功耗。

To solve the power problem in the IC design,the paper presents a RTL low power optimization method through logic reorganization,precomputing and operation isolation which is based on the typical functional simulation. The method works at the RTL level and only need the support of HDL simulation tools. Experimental results show that it can reduce the circuits power dramatically using the method.
