A modified exploration center of gravity for circuit yield maximization

基于R.S.Soin 和 R.spence提出的电路中心值设计的统计最优化方法,文中提出了一种改进的容差域可伸缩的重心游移法。该方法系统地解决了初始状态下,成功点集为空集时的参数中心值设计问题。给出了容差域伸缩策略;区间套舍选抽样策略以及有关系统连接问题。以数值试验和电路设计实例证明了该方法的可行性和实用性。

Based on the statistical optimization method of circuit center design proposed byR.S.Soin and R.Spence,a modified yield maximization technique,moving center of gravity,is suggested.This method is satisfactory in solving circuit yield maximization if the circuitinitial yield is zero.Finally,in order to show feasibility and usability of this method,exam-ples of numerical experiment and circuit yield optimization are given.
