中文摘要
EDA 技术是现代电子工程领域的一门新技术。20世纪90年代以来,EDA发展非常迅速,已成为推动电子工业发展的主要动力。EDA技术的发展和推广应用,对高校电子技术课程教学思想、教学方法和教学目标产生了深远影响,许多高校相继将EDA 作为电子技术教学改革的主要方向,在电子、信息、通信、电气等电类相关专业开设EDA课程,介绍EDA技术。但是，当前的EDA实验系统要么是造价昂贵，要么是外围电路复杂，不能满足高校教学实验的要求。根据可编程器件的特征和“多任务电路结构重配置” 的原理设计了EDA 教学实验系统。该EDA教学实验系统以MAXPLUSⅡ为软件平台,以可编程逻辑器件为核心,应用在系统编程的方法,利用可编程控制芯片的相关电路及其他电路资源, 可完成各种数字电路教学实验。该实验平台提供了丰富的外围设备及各种常用外部设备的端口，功能齐全、使用方便，不仅可用于与计算机专业相关的各类EDA教学的实验与演示，还可用于基于CPLD的各种复杂数字系统的开发。

Title System Of EDA For Teaching And Experiment
Abstract
Electronic design automation (EDA) is new technique in electronic engineering. It developed very quickly and became main development force in electronic industry since 1990`s. EDA affects college teaching ideology, teaching means, teaching goal on electronic circuits course as its development. EDA courses have been opened in many colleges. But, now the EDA systems on the market are ether too costly or their circuits are too complex, which are not suit for the needs of teaching and experiment in university. An EDA teaching experiment box is designed by applying the restructure principle of configuring multitask circuits and the characteristic of programmable logic device. Its software platform is MAXPLUSⅡ and its center is PLD. It can be used for a variety of digital circuit teaching experiments by utilizing programmable control chip and other circuit source. This experiment platform provides rich periphery devices and ports for all kinds of common peripheral equipments. It has complete functions and is easy used. It can be used not only for EDA course related to computer science specialty but also for the development of all kinds of complex digital systems based on CPLD.
