自动售货机设计与实现

深圳大学实验报告课程名称：数字系统现场集成技术实验项目名称：自动售货机设计与实现学院：信息工程学院 专业：集成电路设计与集成系统 指导教师： 报告人：学号：班级：同组人：学号：班级：实验时间：实验报告提交时间：一、实验目的1、进一步熟悉ISE软件的使用，熟悉FPGA开发流程；2、掌握编写fpga代码的步骤，学会绘制ASM图；3、学会调用ip核实现系统的设计。二、实验设备1、装有ISE软件的PC机一台；2、nexys2开发板一块。三、实验内容与要求设计一个秒表基本要求：该实验为团队协作，2人一个小组。可以对3种不同种类的货物进行自动售货,价格分别为A=4.00,B=2.50,C=1.00。售货机可以接受10元,5元,1元三种硬币(即有三种输入信号SY,WY,IY),并且在7段数码管(二位代表元,一位代表角)显示已投入的总钱数,选择货物的输入信号Ia,Ib,Ic,输出指示信号为Sa,Sb,Sc分别表示售出相应的货物,同时输出的信号yuan,jiao代表找零，并显示在7段数码管上。高级要求（可选）：VGA显示3种货物图片及其价格，鼠标点击购买数量（1-9）后显示总价，安规格说明2中的button2-button4输入硬币，VGA显示已投入的总钱数，鼠标点击购买后，显示找零数目，购买物品闪烁，交易完成。规格说明：1. 按一下button1按钮，表示购买货物A，第一个LED灯亮；按两下button1按钮，表示购买货物B，第二个LED灯亮；按三下button1按钮，表示购买货物C，第三个LED灯亮，同时7段数码管显示所要购买货物的价格。2. LED灯亮后，开始输入硬币。button2按一下，输入10元，按两下，输入二十元，以此类推；Button3按一下输入5元，按两下输入10元，以此类推；button4按一下输入1元，按两下输入2元，以此类推。7段数码管显示已投入的总钱数，再次按下button1键，7段数码管显示找零数目，同时指示货物的LED灯熄灭。3. 如果投入的钱币不够就按下button1键确认购买，数码管显示“ER”。4. 本实验使用FPGA板：nexys2（建project时，需要选择该芯片的型号）。四、实验步骤1、设计系统框图，设计采取自上而下的设计方案，整个秒表系统的原理图如下所示。主要包括四个模块——分频模块、vga协议模块、鼠标、vga数据处理模块。而vga数据处理模块里面又有好几个模块–有vga数码管显示模块，显示地址模块（用来生成地址给rom的），还有好多各rom的显示模块，板子按键的处理模块以及鼠标按键的处理模块。总的RTL图分频器Vga协议Vga数据处理MouseVga数据处理总体2、所编写的代码如下。------------------------顶层文件----程序主代码------------------------------------------
