中文摘要
本文是基于Altera公司出品MAX+Plus2软件以及相应的ALTERA FLEX EPF10K10LC84-4实验
平台完成的数字时钟实验，使我们清楚地了解到我们身边的数字时钟的功能是怎样实现的。
数字时钟实验主要包含两个主体时钟基本功能电路、闹钟电路。 主体一：主要涉及模60与模24计数器、动态显示控制电路、分频器主要整点报时电路， 这些电路都是以模块封装好的，以便其他电路调用。以计数器构成计时部件，通过分频器分出的1HZ脉冲计时，调用动态显示电路显示，通过整点报时电路控制蜂鸣器。
主体二：主要涉及模60与模24计数器、显示控制电路、4个数据比较器。以模60与模24计数器构成定时与存储电路，调用动态显示控制电路显示，通过4个数据比较器比较时钟与闹铃的小时、分钟，和后续与门控制蜂鸣器。

英文摘要(Abstract)
This article is based on Altera MAX + Plus2 software company produced and the corresponding ALTERA FLEX
EPF10K10LC84-4 experimental platform to complete the digital clock experiments, so that we clearly understand our side of the digital clock function is how to achieve. Digital clock experiment consists mainly of two basic functions of the body clock circuits, alarm circuits.
The main one: mainly related to mold 60 and the mold 24 counters, dynamic display control circuit, the whole point timekeeping main divider circuits, which are packaged in modules, so that other circuits calls. To constitute a timing counter parts, through the separation of the 1HZ divider pulse timing, called dynamic display circuit display, through the whole point timekeeping circuit control buzzer.
Subject II: mainly related counter mold 60 and the mold 24, a display control circuit, four data comparator. Mold 60 and the mold 24 to form counter timing and memory circuit,

called dynamic display control circuit shows that by four data comparator compares the clock and the alarm hour, minute, and follow-up with the door control buzzer. 关键词：
