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 modern 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.
