中文摘要：

基于CPLD数字系统的设计采用的是VHDL语言描述系统,CPLD是一种下载实体的先进设计方法。文章结合学生的学习特点,就毕业设计指导中,对如何引导学生掌握自顶向下和自底向上的设计方法以及灵活利用文本和图形输入形式进行了研究,分析了芯片下载中易出现的问题并提出了解决方法。教学实践表明,这些教学指导方法具有启发性与可操作性。

英文摘要：

The design method of digital system based on CPLD is an advanced method which is used to describe system with VHDL and download design to CPLD. This paper, based on leaming characteristics, studies how to direct students in graduation design to master the design methods of Top-Down and Bottom-Up as well as how to use nearly input format of text and graph. It analyzes the problems in IC downloading and gives resolving methods. Teaching practice shows that these graduation methods have elicitation and maneuverability.
