{ count_T1=0; // 重新计次

if (++scan==3) scan=1;// 若超过十位数,显示个位

SCANP=~scan; // 输出扫瞄信号

SEG=disp[scan-1]; // 输出显示信号

} // 结束if判断(中断32次)

} // T0中断子程序结束

图11

程序如下：

library IEEE;

use IEEESTD_LOGIC_1164ALL;

use IEEESTD_LOGIC_ARITHALL;

use IEEESTD_LOGIC_UNSIGNEDALL;

entity xuan21 is

Port ( alarm,a,b: in std_logic;

y:out std_logic);

end xuan21 ;

architecture one of xuan21 is

begin

process(alarm,a,b)

begin

if alarm='0' then y<=a;else y<=b;

end if;

end process;

end one;

仿真波形如下图12：

（2）三位二选一：

模块图如图13。用以进行正常计时时间与闹铃时间显示的选择，alarm输入为按键。当alarm按键未曾按下时二选一选择器会选择输出显示正常的计时结果，否则当alarm按键按下时选择器将选择输出显示闹铃时间显示。

图13

程序如下：

library IEEE;

use IEEESTD_LOGIC_1164ALL;

use IEEESTD_LOGIC_ARITHALL;

use IEEESTD_LOGIC_UNSIGNEDALL;

entity x213 is

Port ( alarm : in std_logic;

y:out std_logic_vector(3 downto 0);

a,b: in std_logic_vector(3 downto 0));

end x213;

architecture one of x213 is

begin

process(alarm,a,b)

begin

if alarm='0' then y<=a;else y<=b;

end if;

end process;

end one;

8、整点报时及闹时：

模块图如图15。在59分51秒、53秒、55秒、57秒给扬声器赋以低音512Hz信号,在59分59秒给扬声器赋以高音1024Hz信号,音响持续1秒钟,在1024Hz音响结束时刻为整点。当系统时间与闹铃时间相同时给扬声器赋以高音1024Hz信号。闹时时间为一分钟。

图15

程序如下：

library IEEE;

use IEEESTD_LOGIC_1164ALL;

use IEEESTD_LOGIC_ARITHALL;

use IEEESTD_LOGIC_UNSIGNEDALL;

entity voice is

Port ( hou1,huo0,min1,min0,sec1,sec0,hh,hl,mh,ml: std_logic_vector(3 downto 0);

in_1000,in_500:in std_logic;

q : out std_logic);

end voice;

architecture one of voice is

begin

process(min1,min0,sec1,sec0)

begin

if min1="0101" and min0="1001" and sec1="0101" then

if sec0="0001" or sec0="0011" or sec0="0101" or sec0="0111"

then q<=in_500;

elsif sec1="0101" and sec0="1001" then q<=in_1000;

else q<='0';

end if;

else q<='0';

end if;

if min1=mh and min0=ml and hou1=hh and huo0=hl then

q<=in_1000;

end if;

end process;

end one;

9、顶层原理图：

三、感想

通过这次设计，既复习了以前所学的知识，也进一步加深了对EDA的了解，让我对它有了更加浓厚的兴趣。特别是当每一个子模块编写调试成功时，心里特别的开心。但是在画顶层原理图时，遇到了不少问题，最大的问题就是根本没有把各个模块的VHD文件以及生成的器件都全部放在顶层文件的文件夹内，还有就是程序设计的时候考虑的不够全面，没有联系着各个模式以及实验板的情况来编写程序，以至于多考虑编写了译码电路而浪费了很多时间。在波形仿真时，也遇到了一点困难,想要的结果不能在波形上得到正确的显示

:在分频模块中，设定输入的时钟信号后，却只有二分频的结果，其余三个分频始终没反应。后来，在数十次的调试之后，才发现是因为规定的信号量范围太大且信号的初始值随机，从而不能得到所要的结果。还有的仿真图根本就不出波形，怎么调节都不管用，后来才知道原来是路径不正确，路径中不可以有汉字。真是细节决定成败啊！总的来说，这次设计的数字钟还是比较成功的，有点小小的成就感，终于觉得平时所学的知识有了实用的价值，达到了理论与实际相结合的目的，不仅学到了不少知识，而且锻炼了自己的能力，使自己对以后的路有了更加清楚的认识，同时，对未来有了更多的信心。
