1.绪论
1.1选题的意义
随着社会物质财富的日益增长，安全防盗已成为人们所关注的焦点。传统的钥匙锁芯锁安全性低，需随时携带钥匙，无法满足一些特定场合的应用要求,特别是在人员经常变动的公共场所，如办公室、宾馆、汽车、银行柜员机等地方。电子密码锁越来越受到人们的青睐。目前使用的电子密码锁主要有两个方案：一是基于单片机用分立元件实现的，二是通过现代人体生物特征识别技术实现的，前者电路较复杂且灵活性差，无法满足应用要求；后者有其先进性但需考虑成本和安全性等诸多因素。因此，本设计做了一种新型电子密码锁，采用FPGA芯片，利用先进的EDA技术、ALTERA公司的QUATUSII软件开发平台进行设计。

1.2设计的流程
本设计主要工作流程：

、查阅文献，了解工作原理，确定方案；
、画系统总框图；
、确定硬件模块，设计模块电路方案，绘制总电路原理图；
、软件QuartusⅡ实现，使用VHDL语言设计；
、使用FPGA系列EP2C35F672C8芯片进行硬件测试；
、编写课程设计报告。
2.系统设计原理
2.1 EDA技术及FPGA器件
EDA(Electronic Design Automation，电子设计自动化)技术基于计算机辅助设计，它融合了应用电子技术、计算机技术、信息处理技术、智能化技术的最新成果，以实现技术--电子产品的自动设计。利用EDA工具，电子设计师可以完成概念、算法、协议等设计电子系统的工作，实现电子产品从电路设计、性能分析到设计的整个过程在计算机上自动完成。EDA是现代电子设计技术的核心，在现代集成电路设计中占据重要地位。

FPGA(Field Programmable Gate Array，现场可编程门阵列)作为可编程逻辑器件的典型代表，它是在PAL、GAL、CPLD等可编程器件的基础上进一步发展的产物。它是作为专用集成电路（ASIC）领域中的一种半定制电路而出现的,既解决了定制电路的不足，又克服了原有可编程器件门电路数有限的缺点。它的出现及日益完善适应了当今时代的数字化发展浪潮，它正广泛应用在现代数字系统设计中。

2.2系统设计原理及框图
<1>系统设计原理：

密码锁通过按键和拨码开关给芯片输入信号，芯片通过构建4-7线译码器译码后输出七线信号（八段数码管小数点位未使用）送数码管显示当前密码；芯片通过构建密码比较模块对输入密码进行比较，并输出LED灯，红绿灯、16*16点阵及步进电机控制信号。

通过以上流程，采用EDA技术，FPGA器件实现四位密码控制的电子密码锁功能。

<2>系统总框图：

本系统采用自顶向下的设计方式，各部分功能相互协调，流程明确。为了更加明确各部分的工作，因此在框图中单独把FPGA提出来看，实际上，密码比较模块是在FPGA内部做成的电路

系统总框图2-1

3.硬件部分
以下各模块设计后未进行软件仿真，而分别进行了硬件电路的实际验证，且符合模块设计要求，最后各模块组成顶层电路，再次进行验证，得到了预期的结果。

3.1顶层设计原理图
由于本设计各个模块分布较多且复杂，不利于采用VHDL语言编程实现各个模块的连接，而原理图能够直观表现各模块连接关系和信号流动方向，且便于设计中更改各部分模块的使用，故本设计顶层采用原理图的方式设计。

图3-1

3.2 数码显示模块
数码显示模块采b1，b2，b3，b4四个拨码开关输入4位二进制数，模块译码为七线输出，a，b，c，d，e，f，g分别输出数码管段码信号，实现实时显示拨码开关输入的密码值。供用户确认输入的各位密码值。

图3-2

3.3 数码位选模块
数码位选模块的功能主要是在输入按键按下一次后，k,k1,k2,k3中出现一位信号，控制数码管位选，按键不断按下，表示输入不同位的密码，k,k1,k2,k3依次输入一位高电平信号，a,b,c输出”000”--”011”信号，数码管依次在第0位到第3位显示输入的密码值。以此提示用户应该输入第几位密码。

图3-3

3.4 密码比较模块
密码比较模块中b1,b2,b3,b4代表输入的四位二进制密码，通过对预先设定的密码比较，如果相同，则持续输出高电平，反之，输出持续低电平；

通过密码比较位控制模块确定对比哪一组密码，在设计中，本模块初始化密码为”0001”，”0010”，”0100”，”1000”（取值顺序从左到右）数码管依次显示8421四位密码。密码输入错误则验证不成功。

图3-4

3.5 密码比较位控制模块
密码比较位控制模块中，k0每接收到按键一次高电平，则k，k1，k2，k3依次输出高电平，以此确定密码比较模块中应当比较的密码。（由于实际按键有抖动，按下一次按键会产生电平波动，故在编程中采用了多次高电平累加产生一次进位信号，从一定程度减小误操作）。

图3-5

3.6 点阵显示模块

<1>如图3-6-1点阵字选模块中，clkl 表示输入较低的时钟频率，使在实际显示中每个字变换的速度减慢，en信号由密码比较模块提供，它的高低电平能够控制点阵显示的两组汉字。

点阵扫描模块中，clkh 表示输入较高的时钟频率，使点阵各行扫描速度较快，达到一定速度后，人眼形成残影，从而实现显示汉字的功能。

点阵字库中存储了显示的汉字，扫描方式，通过接收字选信号和扫描信号，产生16+16位输出信号。

图3-6-1

<2>如图3-6-2为方便顶层原理图设计，简化顶层图形复杂度，故将图3-6-1中各模块整合为一个模块，并进行电路验证，原有功能成功实现，模块符合设计要求。

图3-6-2

3.7 分频模块
在电子密码锁中，我们采用的输入时钟信号（CLK）频率为1KHz，通过计数器计数产生震荡，实现分频的功能，图3-7-1中，clk10和clk20实现了不同的降频，用于不同模块需要的频率，图3-7-2中，clk200采用的是clk10和clk20级联的方式实现更大的分频功能的，原因是累计计数会增加误差，而采用级联的方式则减小了这一因素。

图3-7-1

图3-7-2

3.8 D触发器
D触发器使用在按键输入时的消抖电路中，他的使用方式参照了《EDA技术实用教程》中的---逻辑方式去毛刺，并减少了对D触发器的使用，使得按键脉冲能够及时送到相对应的电路中，完成后继操作。

图3-8

3.9 各部分硬件使用情况
以上介绍了各部分模块的设计方式及简单的功能描述，这里介绍一下对实验室硬件资源的使用情况。

<1> LED灯：LED1-LED4分别提示输入的密码是哪一位，4个LED灯同一时刻只能亮一个。

<2> 红绿灯：为方便验证设计，采用红绿灯分别指示密码是否输入正确。

<3> 16*16点阵：显示设计中所需要的汉字提示

<4> 步进电机：密码锁打开时，步进电机开始转动，从形象上表示开锁。

<5> 拨码开关：K1-K4输入组成四位二进制密码供用户输入密码及相关模块验证密码。

<6> 按键：使用S2按键，使数码管产生移位信号、密码验证模块选择验证模块以及LED灯的提示信号。

<7> 数码管：实时显示用户输入的密码值，只有当按键S2按下后才生效，故数码管实时显示的密码值不一定为输入的密码值。

4.软件部分
本设计主要工作是用电脑编程和绘制原理图进行的，运用了QuartusⅡ软件和VHDL硬件描述语言。

4.1 QuartusⅡ介绍
QuartusⅡ是Alt era提供的FPGA/CPLD开发集成环境，也可用于SOPC的设计环境。 QuartusⅡ提供完善的 timing closure 和 Logic Lock 基于块的设计流程。QuartusⅡ包括以timing closure和基于块的设计流为基本特征的PLD的软件,QuartusⅡ设计软件改进了性能、提升了功能性、解决了潜在的设计延迟等，在工业领域率先提供FPGA与mask-programmed devices开发的统一工作流程。QuartusⅡ是Altera公司的综合性CPLD/FPGA开发软件，原理图、VHDL、VERILOG HDL以及AHDL（ALTERA Hardware 支持Description Language）等多种设计输入形式，内嵌自有的综合器以及仿真器，可以完成从设计输入到硬件配置的完整PLD设计流程。

在本设计中，我们使用的是Altera公司的QuartusⅡ6.0进行编译 。

4.2VHDL语言介绍
VHDL 的英文全名是VHSIC Hardware Description Language(VHSIC硬件描述语言)。VHSIC是Very High Speed Integrated Circuit的缩写，是20世纪80年代在美国国防部的资助下始创的，并最终导致了VHDL语言的出现。1987 年底，VHDL被 IEEE 和美国国防部确认为标准硬件描述语言。VHDL主要用于描述数字系统的结构，行为，功能和接口。除了含有许多具有硬件特征的语句外，VHDL的语言形式和描述风格与句法是十分类似于一般的计算机高级语言。VHDL的程序结构特点是将一项工程设计，或称设计实体（可以是一个元件，一个电路模块或一个系统）分成外部（或称可视部分，及端口）和内部（或称不可视部分），既涉及实体的内部功能和算法完成部分。在对一个设计实体定义了外部界面后，一旦其内部开发完成后，其他的设计就可以直接调用这个实体。这种将设计实体分成内外部分的概念是VHDL系统设计的基本点。

VHDL语言的优点：设计方式多样、具有强大的硬件描述能力和移植能力、与器件无关、易于共享和复用

总结
本设计从最初的选题到报告的完结历时一个多月，其中经历了很多次实现方案的改动，与最初的模型有本质上的差别。在这个过程中，我对VHDL语言更加熟悉了，也熟悉了Quartus这个集成开发环境，操作相对以前更加熟练。在实际操作过程中，我遇到了许多问题，最棘手的问题是对VHDL语言的不熟悉，许多知识没有掌握，以至于在编写时经常遇到许多报错，有些错误还能折腾许多时间，由于设计时间相对较少，不支持我这样的慢速低效率，以至于许多预想模块都被搁置，同时采用了太多的小模块降低了电路的可靠性和稳定性。

非常感谢肖敏老师上课时孜孜不倦的讲解和对实验的指导，让我对EDA技术有了初步的了解。同时，感谢那些在设计中给予我们帮助的同学，使我发现并解决了许多问题，才能顺利完成课程设计。
