基于FPGA的带闹钟功能的数字钟设计VHDL代码Quartus仿真

名称：基于FPGA的带闹钟功能的数字钟设计VHDL代码Quartus仿真

软件：Quartus

语言：VHDL

代码功能：

数字钟

1、可以调节小时、分钟；

2、可以调整闹钟时间；

3、到设置的时间闹铃响；

4、整点报时。

设计文档：

控制方法：

2个拨码开关SW0和SW1控制模式：

SW0=0，SW1=0为正常计时模式；

SW0=0，SW1=1为修改时间模式；

SW0=1，SW1=0为显示闹钟时间模式；

SW0=1，SW1=1为修改闹钟时间模式；

2个按键，BT0修改小时，BT1修改分钟：

将拨码开关设置为SW0=0，SW1=1，此时可以修改当前时间；

将拨码开关设置为SW0=1，SW1=1，此时可以修改闹钟时间；
