基于eda的万年历设计说明

1、 EDA设计实验报告学校：大学专业：测控技术与仪器班级：一班：史占东辅导老师：郭敏一、设计要求：（1）、能够显示年、月、日、时、分、秒、星期；并具有闰年判断补偿功能；（2）、具有整点报时与定时功能；二、实用方法：设计中用到了6个按键，在模式5下，K1,K2,K3,K4,ZHENG,NAO；其中K1用于切换显示模式，刚开始时显示时间，按两次K1显示定时时间，再按两次K1显示日期，再按两次重新显示时间；K2用于控制中间信号W，每按下两下中间信号加一，加至8时清零，W=1时，每按两下K3键分钟加一；W=2时，每按两下K3键小时加一；W=3时，每按两下K3键星期加一；W=4时，每按两下K3键日期加一；

2、W=5时，每按两下K3键月份加一；W=6时，每按两下K3键年低两位加一；W=7时，每按两下K3键年高两位加一；W=8时，当K4=0时，每按两下K3键定时分钟加一；当K4=1时，每按两下K3键定时小时加一；按键ZHENG为整点报时的使能端；按键NAO为定时闹钟的使能端。 三、程序与仿真：（1）24进制计数器程序与仿真图如下：library ieee;use ieee.std_logic_1164.all;use ieee.std_logic_unsigned.all;entityt24 isport(clk:in std_logic;q1,q2:out std_logic_vector(3 do
