"FPGA实现的多功能数字钟设计及实现（基于VHDL语言）"

Based on the VHDL language and implemented on FPGA, this design utilizes EDA technology to create a digital clock system. Using a top-down design approach in the MaxplusII software environment, various basic modules are integrated to form the clock system, which consists of a clock module, control module, timing module, data decoding module, display module, and timekeeping module. The EP1K100QC208-3 chip is used to execute the program, allowing for the display of year, month, day, hours, minutes, and seconds, along with features such as setting the clock, resetting it, and starting and stopping it via keyboard input. Through compilation and simulation, the program is downloaded onto a programmable logic device for verification. This system effectively demonstrates the functionality of a digital clock and showcases the capabilities of hardware description languages, FPGA technology, and keyboard interfaces.
