Multisim-Based Digital Clock Design

This paper is based on Multisim 12.0 digital clock design and simulation, focusing on the working principle of digital clock, analysis and design of digital clock circuit. The use of digital chip 74LS160 to realize hexadecimal, twenty-four counting function, the use of 555 timer design seconds pulse generator, the use of combined logic circuit to realize the hour and minute calibration function. After completing the circuit simulation design of each module, the Multisim platform is used to test whether the functions of timing, calibration, pulse generation and frequency division can be realized normally.
