摘　　要：基于探索仿真三态门总线传输电路的目的,采用Multisim10仿真软件对总线连接的三态门分时轮流工作时的波形进行了仿真实验测试,给出了仿真实验方案,即用Multisim仿真软件构成环形计数器产生各个三态门的控制信号、用脉冲信号源产生各个三态门不同输入数据信号,用Multisim仿真软件中的逻辑分析仪多踪同步显示各个三态门的控制信号、数据输入信号及总线输出信号波形,结论是仿真实验可直观形象地描述三态门总线传输电路的工作特性,所述方法的创新点是解决了三态门的工作波形无法用电子实验仪器进行分析验证的问题。The articlels purpose is to explore the three states gate bus transmission circuit simulation, utilizes MultisimlO simulation program to verified the three states gate through a bus connection time-sharing working waveform by simulations and experiments, and give the simulation scheme. Utilizes ring counter of Multisim simulation program to generate the control signal, utilizes pulse signal source to generate the input three state gate with different data input signal. Utilizes logic analyzer of Muhisim simulation program to display the each control signal, data input signal and the bus output signal waveform with synchronization and more trace. The conclusion is that it can describe the working process of three state gate intuitively. The innovation of the method is that it can solve the problem of three state gate working waveform that cannot be verified and analyzed by electronic apparatus.
