【摘要】 提出一种基于Wiener滤波器的波形比较方法,应用于数模混合电路的最坏情况分析.该方法能考虑一定的时间容限和信号容限,自动比较电路在不同的工艺参数、电压和温度(PVT)组合下的仿真波形,通过波形形状的比较来实现电路性能验证,有效地提高了电路验证效率.此方法成功地运用到波形比较软件系统中,并已在Intel技术开发(上海)公司内部推广使用.更多还原

【Abstract】 A novel waveform comparison method based on Wiener filter is presented for worst case analysis.Sets of simulation of different process parameters,voltages and temperatures(PVT) can be compared automatically by the method taking some time tolerance and signal tolerance into account,to speed up mixed-signal simulation check.The resulted waveform comparison system has been successfully integrated into the design flow in flash design of Intel Inc.更多还原
