要本次设计在EDA开发平台QUARTUS6.0上利用VHDL语言设计六人抢答器电路。电路中设有六个抢答键，可供六人同时抢答；我们利用一个二十进制计数器,将其输入频率设定为一赫兹,成功实现了二十秒倒计时的功能；我们利用VHDL语言中的IF和CASE语句结合空操作语句NULL实现开始抢答与超前抢答的区别；各个模块配以一时钟频率由蜂鸣器输出可实现抢答成功、超前抢答犯规、超时抢答等各种情况的报警效果；本设计采用的是杭州康芯电子有限公司生产的GW48系列/SOPC/EDA实验开发系统，FPGA目标芯片型号为Altera公司的Cyclone系列中的EPIC6Q240C8。芯片配置成功后锁定引脚下载即可进行硬件测试：选择实验电路结构图NO.5，使CLK1与CLKOCK5相接(接受1024Hz时钟频率)，CLK 与CLOCK0相接(接受1Hz时钟频率)，报警输出接SPEAK，六位选手分别对应实验箱上的16键，键7为抢答开始键，当其未按下就进行抢答则为超前犯规，按下后二十秒倒计时开始，选手进行抢答，按实验箱上的复位键则可重新开始下一轮的抢答。关键词：六人抢答器；数码显示；信号封锁；犯规报警。目 录六人抢答器设计要求抢答台数为6；具有抢答开始后20秒倒计时，20秒倒计时后六人抢答显示超时，并报警；能显示超前抢答台号并显示犯规报警；系统复位后进入抢答状态，当有一路抢答按键按下，该路抢答信号将其余各路抢答信号封锁，同时铃声响起,直至该路按键松开,显示牌显示该路抢答台号。1 总体设计方案论论证与对比1.1 方案一 该方案方框图如图1：二十秒倒计时模块数码管蜂鸣器锁存器模块抢答鉴别模块按键输入图1 方案一方框图在该方案中，由二十秒倒计时模块、抢答鉴别模块、锁存器模块等模块组成3。蜂鸣器和数码管分别起报警和显示台号的作用。但该方案中的数码管显示是由七段显示器的形式来显示台号的，由于实验箱电路结构与按键数目的限定，使得我们没有采用该方案。1.2 方案二 该方案方框图如图2：图2 方案二方框图抢答成功按键判别模块蜂鸣器抢答报警模块数码管 超前抢答判别模块译码器二十秒倒计时 模块按键输入此方案中整个电路主要由超前抢答判别模块、二十秒倒计时模块、抢答成功按键模块、抢答报警模块四个模块组成4。其台号的显示都是将信号送入译码器译码之后再由数码管显示出来，结合前面六位选手的按键及开始键可得实验箱上模式5的电路结构满足硬件测试的要求。所以我们选定该方案来进行我们这次的课程设计。2顶层电路VHDL程序设计顶层电路VHDL程序如下USE

单元模块程序设计根据顶层原理图，共分为anjian模块、chaoqian模块、daojishi模块、qiangdabao模块这四个模块。其中anjian模块的功能是锁定抢答成功的选手的台号并显示，chaoqian模块可将超前抢答了的选手台号显示出来并伴随报警，daojishi模块进行二十秒倒计时并显示超时报警，qiangdabao模块主要是为抢答成功之后提供报警功能2。3.1 二十秒倒计时模块
