Multisim软件的SPICE仿真分析

Analysis of Spice Simulation in Multisim

Multisim软件以其突出优点易用性在国内得到广泛应用,它使用户可以在无需深入了解SPICE技术的情况下快捷地搭建并仿真电路,但这往往使用户忽略Multisim的SPICE仿真的本质,不利于SPICE的学习和研究。本文从导入SPICE编写的网表文件入手,利用Multisim提供的XSPICE命令行接口和用户自定义分析仿真单端输入差分放大电路,结果和常规的原理图仿真分析相同,作为抛砖引玉,加强用户对Multisim仿真本质理解和对SPICE的深入学习和应用。

Muhisim is widely used in China for its outstanding advantages of ease of use, which allows users build and simulate of the circuit quickly without the need for in - depth understanding of the SPICE technology, but it often makes users ignore the nature of Multisim＇s SPICE simulation,which is not conducive to study and research on SPICE. This paper start from loading netlist files encoded in SPICE, using XSPICE command - line interface and us- er defined analysis provides by Muhisim to simulate a single - ended input differential amplifier circuit, the results is the same with the conventional schematic simulation analysis, as serve as a catalyst, enhance users＇ understanding of Multisim Simulation in nature and the in - depth study and application of SPICE.
