VIVADO彈球游戲VGA顯示Verilog代碼EGO1開發(fā)板游戲

名稱：VIVADO彈球游戲VGA顯示Verilog代碼EGO1開發(fā)板游戲（代碼在文末下載）

軟件：VIVADO

語言：Verilog

代碼功能：

設(shè)計(jì)一個(gè)彈球游戲，并在VGA顯示器上顯示。

1、可以控制游戲開始，開始時(shí)數(shù)碼管顯示0分。

2、使用按鍵控制球拍的運(yùn)動(dòng)，當(dāng)控制球拍接住球時(shí)，分?jǐn)?shù)加1。

3、彈球觸碰屏幕邊緣或者球拍時(shí)可以反彈。

4、當(dāng)未成功接球時(shí)，游戲結(jié)束。
