PSpice软件在基础实验教学中的应用

Application of PSpice Software in the Basic Experimental Teaching

PSpice软件是可以在PC机上完成电路的系统级综合、仿真的一种通用电路模拟仿真软件,他能够代替面板、示波器等整个电子实验室的功能,对复杂的电路与系统进行分析。他在电路、模拟电子技术、数字电子技术、控制理论等方面都有广泛的应用,非常适合于教学和科研,是目前EDA软件种类中具有广泛影响的软件之一。本文首先介绍了PSpice仿真软件的功能、特点以及用PSpice进行分析设计电路的流程,并通过一个低通滤波器作为实例,对PSpice支持的文本输入法和原理图输入法进行了比较,最后分析了PSpice软件在基础实验教学中的作用,并指出仿真实验一定要与实际硬件操作实验相结合,才能真正达到理论与实践相结合的目的。

PSpice is a sort of electrocircuit simulation software that can complete system integration and emulation on the computer. It can replace the function of the panel and oscillograph and entire electro laboratory etc. It analyzes complicated circuit and system. It has widely application in a lot of aspects such as circuit, analog electronics, digital electronics, control theory etc. It is very fit for teaching and scientific research. It is one of the extensive influencing software in EDA category at present. Firstly, its function and characteristic and the working flow of analyzing and designing circuit are introduced.And then, as a concrete example with a lower pass filter, comparing the method of inputting of the text source program and principle chart supported by PSpice.Lastly, the important part of the PSpice software applying in the basic experimental teaching is emphatically analyzed. It is pointed out that emulation experiment and hardware manipulation should be coupled in order to combine the theory with practice.
