Abstract
This paper has been prepared utilizing material from Design and Evaluation, Inc.'s (D&E) training course and engineering handbooks on worst case circuit analysis (WCCA). The WCCA training course was developed by D&E and upgraded under contract to NASA's Jet Propulsion Laboratory to standardize an approach to performing worst case circuit analysis and to exemplify the methodologies and tools for completing a customer acceptable worst case circuit analysis final report. The WCCA methodologies discussed herein for the development of a worst case parts variation database, sensitivity analysis and the mathematical approaches of the extreme value analysis (EVA), root-sum-square (RSS) and Monte Carlo analysis for solving circuit equations and combining variables have become an accepted industry standard over the last eight years.
本文利用设计与评估公司(Design and Evaluation, Inc.)的培训课程和最坏情况电路分析(WCCA)工程手册中的材料编写而成。WCCA培训课程由D&E开发,并根据NASA喷气推进实验室的合同进行升级,以标准化执行最坏情况电路分析的方法,并举例说明完成客户可接受的最坏情况电路分析最终报告的方法和工具。本文讨论的WCCA方法用于开发最坏情况零件变化数据库,灵敏度分析和极值分析(EVA)的数学方法,根和平方(RSS)和蒙特卡罗分析用于求解电路方程和组合变量,在过去八年中已成为公认的行业标准。
