摘　　要：介绍用Multisim仿真软件分析移位寄存器逻辑功能的方法,验证了4-D触发器构成的移位寄存器的逻辑功能。用Multisim仿真软件中的字组产生器产生的信号作为移位寄存器的时钟脉冲和输入数据,字组内容反映移位寄存器的输入信号和控制信号,用Multisim中的逻辑分析仪多踪同步显示各输入信号、控制信号和输出信号波形,直观地描述移位寄存器的工作过程。所述方法创新地解决了移位寄存器工作过程无法用实验仪器验证的问题。The method of using Multisim simulation software to analyze the working process of the shift register is introduced. The logic function of a shift register composed of 4-D flip-flop is verified. The signal yielded by character set generator in Multisim simulation software is taken as the clock pulse and input data of the shift register. The contect of the character set reflects the input and control signals of the shift register. The logic analyzer in Multisim is employed to synchronously display the waveforms of each input signal, control signal and output signal, and to make the working process of shift register he described visually. The innovation of this method is that the problem that the working waves of shift register can not be analyzed and verified with electronic instruments is solved.
