Quartus电子拔河游戏VHDL代码开发板

名称：Quartus电子拔河游戏VHDL代码开发板

软件：Quartus

语言：VHDL

代码功能：

设计一个能进行拔河游戏的电路。

电路使用15个(或9个)发光二极管表示拔河的“电子绳”,开机后只有中间一个发亮,此即拔河的中心点。

游戏甲乙双方各持一个按钮,迅速地、不断地按动产生脉冲,谁按得快,亮点向谁方向移动,每按一次,亮点移动次。

亮点移到任一方终端二极管,这一方就获胜,此时双方按钮均无作用,输出保持,只有复位后才使亮点恢复到中心。

由裁判下达比赛开始命令后,甲乙双方才能输入信号,否则输入信号无效。

用数码管显示获胜者的盘数,每次比赛结束自动给获胜方加分。
