Design of Intelligent Digital Clock Based on FPGA

This paper takes ALTERA EP4CE6E22C8N as the control center, and designs a multifunctional digital clock system based on FPGA, which consists of clock module, timing module, power module, keyboard control module, data decoding module and digital tube display module HDL designs text input for the system logic description language. In the QUARTUSII tool software environment, based on the top-down design idea of FPGA, hierarchical modeling of digital clock circuit is completed by text file input, and the digital clock based on FPGA is constructed jointly by each basic module. After the program is compiled and simulated, download it on the core board to review. This system can realize the function of displaying time in hour, minutes and seconds in turn, calibrating with keys, timing on the hour and alarm clock.
