摘要：pork以硬件描述语言（Verilog或VHDL）所完成的电路设计，鲤鱼可以经过简单的综合与布局，鲤鱼快速的烧录至草鱼FPGA草鱼上进行测试，鲤鱼是现代草鱼IC设计验证的技术主流。草鱼这些可编辑元件可以被用来实现一些基本的逻辑门电路（比如AND、porkOR、porkXOR、porkNOT）或者更复杂一些的组合功能比如解码器或数学方程式。草鱼在大多数的FPGA里面，鲤鱼这些可编辑的元件里也包含记忆元件例如触发器（Flip－flop）或者其他更加完整的记忆块。草鱼草鱼
第1章草鱼草鱼引言草鱼
本设计是基于FPGA利用VHDL语言实现硬件电路的描述实现一个智力抢答器的设计，鲤鱼完成6位选手在规定的时间内（10秒）按键抢答；pork抢中编号锁定显示，鲤鱼其他无效；pork主持按键控制清零和开始选手抢中后在规定的时间内（30秒）答提;pork具有报警提示功能，鲤鱼分别提示抢答开始，鲤鱼有人抢答，鲤鱼抢答时间到，鲤鱼答题时间到。草鱼报警延时为1s；pork。草鱼设计使用的FPGA软件开发平台为Xilinx的ISE，鲤鱼它具有界面简单、pork简单易学、pork辅助功能强大等特点。草鱼在编写代码时可以使用编写向导生成头文件和模块框架，鲤鱼也可以使用语言模块帮助编写代码。草鱼实验使用的仿真软件为ModelSim，鲤鱼该软件具有代码分析能力可以看出不同代码段消耗资源的情况。草鱼其功能侧重于编译和仿真，鲤鱼不能制定编译的器件和不具有下载配置能力，鲤鱼所以需要和ISE等软件关联使用。草鱼草鱼
第2章草鱼草鱼实验项目方案设计草鱼
2.1草鱼草鱼项目系统设计原理草鱼
系统主要要实现计数功能、pork显示功能还有数据的锁存和读取。草鱼本设计采用了外部时钟为48Mhz的FPGA硬件开发平台。草鱼首先利用分频器将48Mhz的外部时钟分频产生100hz和1khz的始终信号，鲤鱼100hz的时钟用于实现精度为0.01s精度的计数器时钟，鲤鱼1kHz的时钟信号用于显示模块扫描显示的外部信号。草鱼计数器为两个六进制计数器和四个十进制计数器的同步级联，鲤鱼同时具有清零，鲤鱼暂停控制端口。草鱼显示模块6只数码管采用动态扫描的连接方式，鲤鱼硬件电路上的每个数码管abcdefg分别连在一起，鲤鱼作为段选信号，鲤鱼8个数码管数码管分别由8个选通信号控制（这里使用到了三八译码器），鲤鱼由于段选信号连在一起，鲤鱼所以数码管的显示采用的是动态扫描的显示方式。草鱼锁存模块设计时采用了六进制的计数器输出端触发，鲤鱼有效地完成了锁存六个时间点的实验要求，鲤鱼同时加入了数据锁存和数据输出选择键，鲤鱼完美实现了锁存数据的输出。草鱼草鱼
2.2草鱼草鱼项目系统设计方案及模块组成草鱼
图一为此次设计的基本构架和模块组成（不包含消抖模块）。草鱼草鱼
系统的主要组成模块主要有消抖电路模块、pork分频器模块、pork计数器模块、pork锁存器模块、pork扫描显示模块、pork译码器模块、pork势能/选择模块。草鱼各模块的功能描述，鲤鱼将在第三章作介绍。草鱼草鱼

草鱼
具体的实现过程为：pork下载完成后按下get键，鲤鱼此时使能模块输出高电平，鲤鱼计数器开始计时，鲤鱼并在数码管上实时显示，鲤鱼锁存器模块进入锁存状态，鲤鱼start为系统的清零/复位键，鲤鱼sc为六进制计数器的时钟，鲤鱼每按一次sc键将会产生一个上升沿，鲤鱼并计数一次，鲤鱼六进制的计数器的输出端触发锁存器，鲤鱼每记一次数锁存一组数。草鱼草鱼
当再按一次get键的时候，鲤鱼势能/选择模块输出低电平，鲤鱼此时计数器停止计时，鲤鱼锁存器进入数据读取状态，鲤鱼显示模块显示读取的锁存的数据，鲤鱼按下start键为系统清零，鲤鱼当每按一次sc键，鲤鱼锁存器将会按锁存的顺序读取锁存的数据并显示该数据时第几次锁存下的。草鱼草鱼
第3章草鱼实验项目单元模块电路设计草鱼
3.1草鱼消抖模块设计草鱼
3.1.1草鱼草鱼模块描述草鱼
分频器的功能是提供计数器的时钟信号以及数码管动态扫描部分的时钟信号。草鱼由于系统的外部时钟为48Mhz，鲤鱼而根据跑表的精度要求0.01s，鲤鱼计数器的时钟信号应为100hz，鲤鱼因此需要对48MHZ的时钟信号进行分频，鲤鱼得到100hz的信号，鲤鱼作为时钟的计数时钟。草鱼根据显示部分的原理，鲤鱼需要1khz的扫描控制信号，鲤鱼因此在分频器部分还要产生1khz的信号。草鱼草鱼
分频器的设计采用基于计数器的方法来实现。草鱼在本设计中，鲤鱼在程序的第一个进程中设计了一个24000进制的计数器，鲤鱼当计数24000个时钟，鲤鱼分频输出信号clk1kHz取反，鲤鱼这样就可以实现对输入时钟的48000次分频，鲤鱼从而得到1kHz的输出信号。草鱼在第二个进程中采用同样的方法对已经得到的1khz的信号进行10分频得到100hz的输出信号clk100hz。草鱼分频模块如图二所示：pork草鱼

3.2计数器模块的设计草鱼
3.2.1草鱼模块描述草鱼
由于要求秒表显示为六位，鲤鱼每一位可以视为一个一位计数器，鲤鱼则跑表的计数过程可由6个一位计数器级联完成，鲤鱼其中包括十进制的计数器4个，鲤鱼六进制的计数器2个。草鱼其中rst是清零端，鲤鱼clk100hz是计数器信号输入端，鲤鱼carryin是计数器的使能端，鲤鱼高电平时计数，鲤鱼低电平时停止计数且保持计数不变。草鱼Carryout是计数结果的输出，鲤鱼countout是进位端。草鱼下图为计数器的同步级联原理。草鱼草鱼

3.3显示模块设计草鱼
3.3.1模块描述草鱼
草鱼
本设计中7只数码管采用动态扫描的连接方式。草鱼硬件电路上的每个数码管abcdefg分别连在一起作为段选信号。草鱼根据硬件电路的连接方式，鲤鱼如果希望七个数码管显示计数器输出的数据，鲤鱼就必须是的7个选通信号分别被单独选通，鲤鱼所以我们设计了sel输出端作为位选信号的输出端。草鱼LED为7段数码管的段选信号的输出端。草鱼草鱼
counterout1—counterout7为计数器实时计数显示的输入端口，鲤鱼Countout1—Countout7为锁存输出信号显示的输入端。草鱼e为选择输入端，鲤鱼当e为高电平时，鲤鱼显示模块的将显示counterout1—counterout7的信号。草鱼草鱼
当e为低电平时，鲤鱼显示模块将显示Countout1—Countout7的信号。草鱼草鱼
Clk1khz为时钟信号的输入端。草鱼高频率的时钟可以保证人眼很难分辨出数码管的独立显示。草鱼草鱼
G为低电平有效，鲤鱼根据硬件电路，鲤鱼需设置一个译码势能信号。草鱼草鱼

3.4锁存模块的设计草鱼
3.4.1模块描述草鱼
overin为锁存器的锁存或者读取的出发端。草鱼直接与六进制计数器的输出端连接，鲤鱼接收触发信号。草鱼草鱼
Lachin为锁存/读取的选择端，鲤鱼当lachin为高电平时，鲤鱼锁存器遇到触发（例overin=0010）就会锁存一组数，鲤鱼也就是将numin1~numin7的数据存下来，鲤鱼当lachin为低电平的时候，鲤鱼当遇到触发信号（overin=0010）时，鲤鱼内部锁存的数据（overin=0010时锁存的数据）就会输出到numout1~numout7，鲤鱼连接到显示模块就会显示锁存的数据。草鱼草鱼
numin1~numin7为锁存的输入端，鲤鱼numin1~numin6连接的是计数器的六个输出端。草鱼numin7连接的是六进制计数器的输出端，鲤鱼用于锁存触发信号，鲤鱼以便在后面用作显示锁存数据的顺序。草鱼草鱼
Numout1~numout7为锁存的输出端。草鱼草鱼

波形分析：pork草鱼
从上图可以看出，鲤鱼当lachin为低电平且overin=0001时，鲤鱼numout会输出lachin为高电平时且overin=0001时的numin的输入信号，鲤鱼且lachin为高电平时，鲤鱼numout无输出。草鱼由此可以判断，鲤鱼锁存器的锁存，鲤鱼读取功能已经实现。草鱼草鱼
3.6消抖模块的设计草鱼
模块描述草鱼
消抖模块的主要工作原理就是产生延时，鲤鱼让按键信号延时几个时钟周期。草鱼草鱼
Clk为时钟信号的输入端，鲤鱼在此设计中用的是1000hz的时钟信号，鲤鱼sc，鲤鱼get为按键，鲤鱼xdout，鲤鱼scout为消抖后输出的延时信号。草鱼模块程序：pork草鱼

使能模块的功能是产生计数器的是能控制信号。草鱼根据系统的设计要求，鲤鱼设置开始/停止按键时，鲤鱼该按键每按一次，鲤鱼跑表开始或停止计时，鲤鱼因此，鲤鱼使能模块的功能应该为在输入时钟信号的作用下，鲤鱼输出状态发生翻转。草鱼草鱼

当再按一次get键的时候，鲤鱼势能/选择模块输出低电平，鲤鱼此时计数器停止计时，鲤鱼锁存器进入数据读取状态，鲤鱼显示模块显示读取的锁存的数据，鲤鱼按下start键为系统清零，鲤鱼当每按一次sc键，鲤鱼锁存器将会按锁存的顺序读取锁存的数据并显示该数据时第几次锁存下的。草鱼草鱼
