基于Proteus的单片机电路的虚拟仿真

随着现代计算机技术的迅速发展，使用EDA（电子设计自动化）软件进行的电路设计与仿真已经成为现代电子技术系统设计的必然趋势。文中应用Proteus软件实现了单片机LED（发光二极管）流水灯电路的设计与仿真，介绍了Proteus的单片机软硬件实时动态仿真功能及仿真过程，并给出Keil与Proteus联合仿真的方法。此方法能加深学生对单片机原理的理解，也锻炼了学生进行软硬件综合开发的能力。实践证明，Proteus仿真软件能够提高开发效率，降低开发成本，缩短开发周期。

Virtual Simulation of MCU Circuit Based on Proteus

With the fast development of computer technology, circuit design and simulation based on EDA software has already become a trend in the design of modem electronic system. In this paper, the circuit design and simulation of FlashLED is implemented by means of Proteus software. The Proteus MCU software and hardware real-time dynamic simulation function are introduced, simulation process is described in detail, and Keil and Proteus joint the simulation method is given. It is proved that the new method not only let students understand MCU operation principle, but also practice their capability to realize multiple projects. With the help of Proteus, the designer can improve efficiency, reduce cost and shorten cycle of development of MCU.
