Dynamic power analysis of master-slave D flip-flop(主从型D触发器的动态功耗分析)
Zhejiang Daxue xuebao. Lixue ban, 2003 主从型D触发器的动态功耗同触发器内部节点上的信号跃迁情况和节点电容有关.基于D触发器的电路结构与MOS管参数,本文对主从型D触发器各个节点电容进行了计算.利用对各节点电容的计算值,便可估算在桌一激励输入序列下的D触发器的动态功耗.Pspice模拟证实了该一动态功耗估算的准确性.搞清了D触发器内部诸结点电容与MOS管参数之间的关系亦为降低它的动态功耗提供了参考依据.

Voltage island-aware multiple voltage assignment based on genetic algorithm(基于遗传算法的电压岛感知的多电压分配)
Zhejiang Daxue xuebao. Lixue ban, 2013 功耗是当前SoC设计所面临的最大挑战之一，多电压设计是一种降低SoC芯片功耗的有效方法.在后布局阶段应用多电压设计，首先对现有电源网络复杂性度量方法进行改进，然后提出了一个同时考虑功耗、电源网络复杂性及电平转换器的新目标函数，并采用遗传算法进行最优电压分配.对GSRC测试电路的实验结果表明，所提出的算法不仅能有效降低芯片功耗，同时可以将多电压设计的额外开销控制在一个较低的水平.此外，改进的电源网络复杂性度量方法在功耗节省和电平转换器数量方面较已有的有一定的优势.
