可编程逻辑器件实验板的硬件设计 摘 要 在本论文中，首先介绍了可编程逻辑器件 ，然后介绍了可编程逻辑器件应用于开发板的背景和国内外的发展情况，其次介绍了本课题的意义和内容，以及芯片的选择、设计软件。在本设计中，选用了ALTERA公司的EPM7128SLC84-15N芯片作为核心芯片，用Protel 99se进行设计。实验学习板上包括LED显示、七段数码管、按键输入等常用的功能模块，能让初学者快速验证学习思路，培养学习兴趣。实验板分为一个以EPM7128SLC84-15N为核心芯片的核心板，其他功能模块为基板，它能实现一些简单的输入输出，能完成基本下载，然后利用MAX+PLUS II软件开发环境和VHDL语言进行验证。EPM7128SLC84-15N是ALTERA公司研制的一个CPLD，它具有高密度、低成本、低功耗的特点。EPM7128SLC84-15N功能强大可靠性高，因而设计人员可以轻松地开发集存储器、数字信号处理器以及特殊逻辑等强大功能于一身的芯片。 设计中详细的讲解了每个模块的功能，说明了各器件在电路中的工作方式和连接方法。最后，根据设计出的PCB板图焊接电路做出实验板。 关键词：实验板 CPLD protel99se The Hardware Design of Programmable Logic Device ABSTRACT In this paper, firstly introduced the definition of Programmable logic device and the background of the application in the trainer board and developments at home and abroad,followed the meaning and content of the subject,as well as chip choices,design software and programming software.In this design,the EPM7128SLC84-15N series of chips are used,using Protel 99se design.On the studying boadrd are common function modules ineluding LED display, seven digital tube,key-stroke input,ete.to help novices rapidly confirm their studying thought and nurture studying interest. Through the experimental design, to the target board, a EPM7128SLC84-15N at the core board, and other functional modules for substrate, to achieve some simple input and output, can be downloaded to complete the basic experimental box,and then use MAX+PLUS II environment and VHDL verification.EPM7128SLC84-15N is the one plug-in PLD which was developed by ALTERA,it has these characteristics like high-density,low-cost,low-power,etc.It is one of the best device serials in the contemporary application of Altera CPLD. EPM7128SLC84-15N powerful high reliability, and thus designers can easily set the development of memory, digital signal processors and special logic functions such as powerful chips. Design in detail the function of each module that all devices in the circuit connecting the working methods and app
