基于SIMULINK的计数译码显示电路的仿真

The simulation of the count-decode-display circuit based on SIMULINK

在Simulink环境下包含着许多典型的数字电路仿真模块。本文先以计数器为例,根据其逻辑功能,采用触发器来实现,并封装成模块。然后利用组合逻辑电路设计出译码电路模块,接着设计了LED数码管显示电路,并将三者组合成计数译码显示系统仿真模型。设计与仿真结果验证了此设计的正确性和可靠性,同时也表明,运用Simulink进行对电路虚拟仿真,可以方便、有效地进行数字电子电路的设计和分析。

Simulation modules related to digital circuit are offered in Simulink.ln this paper, at first,counter is designed by using triggers according to its logic function, and packaged into a module.Then, the decoder module is built by using combinational logic circuit, and the LED displaying circuit also. Finally all three circuits are combined into a count-decode-display system.The simulation results verify the correctness and reliability of the design, and also show that the design or analysis of digital circuits can be carried out conveniently and effectively by using software of Simulink to simulate the circuit.
