贪吃蛇游戏DE1SOC开发板VGA贪食蛇游戏VHDL

名称：贪吃蛇游戏DE1SOC开发板VGA贪食蛇游戏VHDL（代码在文末下载）

软件：Quartus II

语言：VHDL

代码功能：

经典贪食蛇游戏VGA

要求：

1、实现经典的贪食蛇游戏。

2、通过4个按键控制蛇的方向。

3、果实可以随机产生。

4、每吃到一次果实，加一分，且蛇变长。

5、使用VGA显示游戏图像。

本代码采用分模块设计，包括：

• 蛇控制模块
• 随机信号产生模块（果实）
• 计分模块
• 导航状态机模块
• 通用计数器模块
• VGA控制模块
• 主状态机模块

本代码已在DE1-SOC开发板验证，其他开发板可以修改管脚适配，开发板如下：
