介绍用Multisim仿真软件进行触发器工作波形仿真分析的方法,目的是探索触发器工作波形的仿真实验技术,即用Multisim仿真软件中的字组产生器产生触发器的时钟脉冲、数据输入、异步控制等多路信号,用Multisim中逻辑分析仪多踪同步显示触发器的各种输入及状态输出波形。并介绍了几种典型触发方式,不同逻辑功能触发器工作波形仿真分析时Multisim中字组产生器的设置方法。该软件可直观形象地描述触发器的逻辑功能和状态变化特点。所述方法的创新点是解决了触发器工作波形无法用电子实验仪器进行分析验证的问题。

To explore the simulation experiment technology of the working waves of flip-flop,the method of applying Multisim to analyze the working wave of flop-flop is introduced.The word generator in multisim simulation software is used to generate signals such as clock pulse,input data and asynchronous control,and the logic analyzer is employed to synchronously display the input and output waves of flip-flop.How to set the word generator is also discussed in several typical trigger modes for different logic functions. As a conclusion,logic functions and states change of flip-flop can be depicted intuitively and vividly.This method settles the question that the working waves of flip-flop are hard to test and verify by electronic devices.
