实验利借助于Quartus II 软件设计了一个多功能数字钟，实现了校时，校分，清零，保持和整点报时等多种基本功能，此外还实现了闹钟，星期，音乐闹铃等附加功能。本文首先利用Quartus II进行原理图设计并仿真调试，最后在实验板上验证了设计的正确性。

-Quartus II software by means of experimental Lee designed a multi-functional digital clock and realized the school, the school hours, cleared, and the whole point of time keeping and other basic functions, in addition to achieve the alarm clock, week, music, alarm, etc. Additional function. This paper carried out using Quartus II schematic design and simulation debugging, and finally verified in the experimental board design is correct. Keywords: digital clock alarm clock simulation of quasi-point of time
