摘 要
本设计为一个多功能的数字时钟,具有时、分、秒计数显示功能,以24小时循环计数;具有校对功能。 本设计采用EDA技术,以硬件描述语言Verilog HDL为系统逻辑描述语言设计文件,在QUARTUSII工具软件环境下,采用自顶向下的设计方法,由各个基本模块共同构建了一个基于FPGA的数字钟。
系统由时钟模块、控制模块、计时模块、数据译码模块、显示以及组成。经编译和仿真所设计的程序,在可编程逻辑器件上下载验证,本系统能够完成时、分、秒的分别显示,按键进行校准,整点报时,闹钟功能。

Abstract
The design for a multi-functional digital clock, with hours, minutes and seconds count display to a 24-hour cycle count; have proof functions function. The use of EDA design technology, hardware-description language VHDL description logic means for the system design documents, in QUAETUSII tools environment, a top-down design, by the various modules together build a FPGA-based digital clock. The main system make up of the clock module, control module, time module, data decoding module, display and broadcast module. After compiling the design and simulation procedures, the programmable logic device to download verification, the system can complete the hours, minutes and seconds respectively, using keys to cleared , to calibrating time. And on time alarm and clock for digital clock.
Keywords: digital clock,hardware description language,Verilog HDL,FPGA
