洛阳理工学院毕业设计（论文） 基于Multisim的电路仿真设计与分析

摘 要

电子技术是电子专业的一门主干课程，该课程既有比较抽象的理论分析又有具体的实践应用。EDA对于这类课程的学习可以做出很大的帮助，而课程学习质量的优势直接影响到该专业的后续课程的学习以及我们的电路理论分析和实践动手能力。电子技术理论的学习应于实验同步进行，以加深感性认识，用仿真软件验证理论分析是可行的有效的方法。

Multisim是知名的EDA软件之一，EDA教学和技术推广已成为当今世界的一个热点，用它可以准确地对电路进行电路仿真及其分析。通过几个电路设计实例的仿真分析，表明使用Multisim软件进行电路设计可以方便地搭接各种电路，连接虚拟仪表，运行仿真可以测试到精确的数据和形象的波形，不仅可以提高设计效率，而且可以保证设计质量。

Multisim是一种功能比较强大的电子电路仿真软件，利用Multisim软件可以使设计与仿真同步，一边设计一边实践，修改调试也比较方便；仿真实验中又不消耗实际的元器件和损伤测试仪器，实验成本很低，试验速度也比较快；仿真实验成功的电路也可以在产品中直接使用。

洛阳理工学院毕业设计（论文） Based on Circuit Simulation and Analysis of Multisim

ABSTRACT

Electronic technology is the electronic profession a main course ,the course is both more abstract and theoretical analysis there are more specific practical application.EDA for such course of study can make a great help,the course of study directly affect the quality of follow up to the professional course of study and my analysis of circuit theory and practical ability.E-learning technology theory and experiment should be carried out simultaneously to enhance perceptual knowledge,the theoretical analysis with simulation software is feasible and effective method.

Multisim is a well-known EDA software EDA teaching and technology extension have become hot issues in current electronic industry ,It can do a electric circuit simulation analysis exactly.According to the simulation analysis are done on some circuit design examples,the results show that using the Multisim software to design the circuit ,which is convenient to link variety circuits,joint hypo the sized instrument measuring appliance.It can measure the accurate data and waveform figures with running simulation,which not only improve the design efficiency,but also guarantee the quality.

This paper mainly validates the powerful function of Multisim software.Multisim is a multifunctional electronic simulated circuit software,which can design and simulate at the same time,The modification of the circuit is very convenient.By Multisim simulation,cost of experiments can be reduced since no real devices are wasted during the test,Moreover,so the rate of experiments is very fast.The success of circuit simulation can be directly used in the product.

KEY WORDS: Multisim;simulation experiments;circuit design;circuit analysis.
