电子电路PSPICE程序仿真分析

PSPICE Emulational Analysis of Electrocircuit

电子设计的自动化技术(EDA)改变了以定量估算和电路实验为基础的传统分析和设计方法,是现代电子电路分析和设计的重要辅助工具.而电子电路仿真是电子设计的自动化技术(EDA)的一个重要组成部分.PSPICE是当今世界上著名的电路仿真标准工具之一.本文用MicroSim公司出版的基于Windows平台的PSPICE仿真电子电路的电性能,估算元器件变化对电路造成的影响,分析一些较难测量的电路特性,并对PSPICE仿真分析的合理性作进一步的理论论证.为优化设计电子电路、缩短研制周期、降低研制费用提供依据.

Electronic design automation(EDA) has changed traditional analytical methods and designing methods that laid the foundations of quantitative analysis and electrocircuit experimentation.It is a main assistant tool of modern circuit analysis and designing.Electrocircuit emulation is an important part of EDA.PSPICE is one of today's most famous standard software in the world.The paper has used PSPICE under Window published by Microsim company to emulate performance of electrocircuit and analyze electrocircuit affected by changing component element.The paper has also analyzed characteristic of electrocircuit difficult to measure.It has done more demonstrating for rationality of emulation.The study has provided theoretical basis for optimal design of electrocircuit.It is favorable to shorten period of design and reduce cost of design.
