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.
