一课题要求
（1）技术要求
掌握较复杂逻辑的设计，调试。
掌握用VHDL语言设计数字逻辑电路。
掌握quartusII6.0软件的使用方法。
了解8*8列共阴点阵显示器的工作原理和功能。
掌握常用驱动电路的原理及使用方法。
掌握EP2C5T144C8芯片的使用。
（2）功能要求
本设计为基于FPGA的8*8点阵显示器，运用VHDL语言编写软件，并通过硬件来实现显示汉字，及滚动，屏显等功能。
主要功能：
静态显示一个完整的汉字
能一屏一屏动态显示多个汉字
能滚动动态显示多个汉字
能通过开关控制点阵显示方式
（3）本人工作
在此次课程设计中我主要负责软件的编写与仿真。
以及软件的下载。
二设计方案
1原理图
要实现8*8点阵显示器显示动态汉字的功能，主要实现两方面的设计：
硬件部分和软件部分。
2硬件部分
硬件部分主要包括：
驱动电路，点阵显示器，端口降压电路。
本次使用的点阵显示器为列共阴型点阵显示器。
及当行为高电平，列为低电平是对应的发光二极管反光。
硬件部分的主要功能是将软件中输出的行列信号在点阵中显示出来。
3软件部分
软件部分通过调用汉字库的方式来实现汉字的显示。
通过逐列扫描的方法来实现完整的汉字显示。
编辑输入：
首先根据课程设计与硬件要求在quartus中编写软件。
功能仿真与时仿真：
利用EDA工具软件对EDA设计进行模拟，验证设计和排除错误。
锁定端口：
结合硬件要求锁定各个端口。
编程下载：
把生成的编程文件通过编程器载入目标器件，以便进行硬件验证和调试，进而完成设计。
