可容纳四组参赛者的数字智力抢答器VHDL代码Quartus仿真

名称：可容纳四组参赛者的数字智力抢答器VHDL代码Quartus仿真

软件：Quartus

语言：VHDL

代码功能：

设计制作一个可容纳四组参赛者的数字智力抢答器。

1.电路具有第一抢答信号的鉴别和锁存功能。在主持人发出抢答指令后,若抢答成功,则该组指示灯亮。此时,电路应具备自锁功能,使别组的抢答开关不起作用。

2.设置计分电路。每组在开始时预置成50分,抢答后由主持人计分,答对一次加5分,否则减5分。每组选手分值由数码管进行显示。

3.系统主要外设:自恢复式按键5个、蜂鸣器1个、系统时钟(50MH2)、LED灯若干、7段数码管若干。
