：Proteus是一款功能强大的EDA仿真软件。它拥有丰富的库元件，尤其是动态外设的仿真极大地补充了其他仿真软件的不足；虚拟工具箱的引入为仿真测试提供了方便。本文以AVR单片机为例具体分析了该软件在仿真微处理器方面的独到之处，展示了其广阔的应用前景。-: Proteus is a powerful EDA simulation software. It has a rich library of components, especially the dynamic simulation peripherals greatly complement the shortcomings of other simulation software　the introduction of virtual toolbox provides the convenience of simulation testing. In this paper, single-chip AVR as an example a detailed analysis of the software in the simulation of the unique aspects of the microprocessor to display its wide application prospect.
