Electronic products are being carried out at an unprecedented rate of innovation, mainly largescale programmable logic devices in a wide range of applications. Especially in the current semiconductor technology has reached the level of deep submicron chip integration of highreach stem megabits, the clock frequency to the stem MHz is also more than the development of the median data of several billion times per second, the future integrated circuit technology will be the development trend of systemonchip SOC. In order to achieve onchip systemonchip programmable plex programmable logic device (CPLD) and field programmable gate array (FPGA) will bee the future design of electronic systems, a direction of development. Therefore, the development of electronic design technologies to today, will face even greater significance in another breakthrough, FPGA on the basis of a wide range of EDA applications.EDA technology concepts: EDA is the electronic design automation, as it is just a new technology developed, involving a wide range of contentrich, understanding of different, so there is no one precise definitiKEY WORDS■■EDA technology, Electronic Design, EDA technology concept前言 在數(shù)字化的道路上,電子技術(shù)經(jīng)歷了一系列重大的變革。從而實現(xiàn)可編程片上系統(tǒng)芯片CPU(復(fù)雜可編程邏輯器件)和5PGA(現(xiàn)場可編程門陣列)必將成為今后電子系統(tǒng)設(shè)計的一個發(fā)展方向。但從EDA技術(shù)的幾個主要方面的內(nèi)容來看,可以理解為:EDA技術(shù)是以大規(guī)??删幊踢壿嬈骷樵O(shè)計載體,以硬件描述語言為系統(tǒng)邏輯描述的主要表達方式,以計算機、大規(guī)??删幊踢壿嬈骷拈_發(fā)軟件及實驗開發(fā)系統(tǒng)為設(shè)計工具,通過有關(guān)的開發(fā)軟件,自動完成用軟件的方式設(shè)計電子系統(tǒng)到硬件系統(tǒng)的一門新技術(shù)。20世紀70年代的CAD(計算機輔助設(shè)計)階段:這一階段的主要
