4、相应的ALTERAFLEXEPF10K10LC84-4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

5、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。28英文摘要(Abstract)ThisarticleisbasedonAlteraMAX+Plus2softwarecompanyproducedandthecorrespondingALTERAFLEXEPF10K10LC84-4experimentalplatformtocompletethedigitalclockexperiments,sothatweclearlyunderstandoursideofthedigitalclock
