将相邻线间的信号跳变方向考虑到噪声窗口模型中,提高计算同时跳变的干扰线在受扰线上引起的组合噪声脉冲结果的准确性;利用改进的噪声窗口模型,对受扰线的弱干扰线集合、强干扰线集合以及传播噪声同时进行分析,得到电路中精确的可实现有效噪声脉冲以及相应的有效干扰线集合。对10个MCNC基准电路进行实验,结果表明,该方法能够非常有效地滤除功能噪声分析过程中的虚假噪声故障。 Taking the direction of the signal transition between adjacent lines into account in the noise window model, the accuracy of the combined noise pulse caused by the disturbing line at the same time of transition calculation is improved. By using the improved noise window model, The weak interference line set, the strong interference line set and the propagation noise are analyzed at the same time, and the accurate effective noise impulse and the corresponding effective interference line set in the circuit are obtained. Experiments on 10 MCNC reference circuits show that this method can effectively filter out false noise in the process of functional noise analysis.
