Multisim在组合逻辑电路设计中的应用

The Application of Design Combinational Logic Circuits Based on Multisim

介绍了电子仿真软件Multisim在组合逻辑电路设计的常用元件,通过设计一个四变量的楼道路灯控制系统的实例进行探讨。根据电路的功能需求得出逻辑表达式,在Multisim中选用与非门搭建电路并进行仿真。实践证明,基于Multisim设计组合逻辑电路的效率很高,仿真验证比较方便,对实际电路的制作能带来很大帮助,具有较高的实践指导意义。

This paper introduces the interrelated components of Muhisim and gives an example of design a street - lamp con- trol system. Accoding to the functional requirements of circuit, obtaine the logical expression, select the NAND Gates to build and Simulate the circuit by Multisim. The result shows that it is convenient and efficient in designment, simulation, production of combinational logic circuits based on Multisim.
