基于FPGA的乒乓球比赛游戏机设计Verilog代码ISE仿真

名称：基于FPGA的乒乓球比赛游戏机设计Verilog代码ISE仿真

软件：ISE

语言：Verilog

代码功能：

乒乓球比赛游戏机。

功能要求:

1、设计一个由甲、乙双方参赛,有裁判的3人乒乓球游戏机。

2、用多个LED排成一条直线,以中点为界,两边各代表参赛双方的位置,其中一只点亮的LED指示球的当前位置,点亮的LED依此从左到右,或从右到左,其移动的速度应能调节;甲乙双方每隔5次自动交换发球权,拥有发球权的一方发球才有效。

3、当“球”(点亮的那LED)运动到某方的最后一位时,参赛者应能果断地按下位于自己一方的按钮开关,即表示启动球拍击球。若击中,则球向相反方向移动;若未击中,则对方得1分;一方得分时,电路自动响铃,这期间发球无效等铃声停止后方能继续比赛,设置自动记分电路,甲、乙双方音进行记分显示。每计满11分为1局。

整体仿真图

甲发球并得分，甲发球权，乙发球无效

speed_ctrl控制稍球的速度

乙发球，并得分，乙发球权，甲发球无效

乙先得11分，win_led亮
