摘　　要：器件容差分析是电路工程设计中的重要环节,由于容差来源于器件参数的随机变化,所以针对容差的分析多采用统计学方法,需要开展大量的实验测试。在电子线路课程设计的教学中关于容差分析的实践和学习受限于实验手段和课时安排而无法展开。针对这一分析特点,结合具体案例,采用电路仿真软件Multisim中的对应分析功能,对于容差及其影响开展具体的分析和描述,并在此基础上结合仿真结果对于容差分析学习的实验实施提供参考和指导。Device tolerance analysis is an important part in circuit engineering design,since the tolerance comes from the random variation of device parameters,statistical methods are used to analyze the tolerance,and a large number of experimental tests are needed.In the teaching of course design of electronic circuit,the practice and learning of tolerance analysis are limited by experimental means and arrangement of teaching hours.Based on the statistical characteristics of tolerance analysis,the corresponding analysis methods of circuit simulation software Multisim are used to analyze and describe in detail the tolerance phenomenon and their influences.According to the simulation results,reference and guidance for the experiment implementation of the analysis and learning about device tolerance are provided.
