本文在对目前计算机辅助电路设计(CACD)领域进行研究分析的基础上提出CACD应达到的单一目标函数——带状拟合电路技术性能函数曲线,又在分析了原有的计算机辅助分析(CACD)程序后提出一种利用表格——正交表计算电路系统多参数大变化灵敏度的方法,进而举出目前CACD领域内电路分析、电路优化和容差设计中不可避免的一系列困难问题,提出只有把三者和諧地组织在一个软件中才能使这些问题得到合理解决,组成一个CACD通用电路容差优化设计程序。
Based on the research in the field of computer aided circuit design (CACD), this paper proposes a curve of performance function of single objective function-banding fitting circuit which CACD should reach, and analyzes the existing CACD ) Program, this paper presents a method to calculate the large-scale sensitivity of multi-parameters of a circuit system by using the table-orthogonal table, and then presents a series of inevitable problems in circuit analysis, circuit optimization and tolerance design in CACD field. Only the three harmoniously organized in a software in order to make these problems be properly resolved to form a CACD common circuit tolerance optimization design process.
