EDA is Electronic Design Automation (Electronic Automation) is the abbreviation of themselves, in the early 1990s from computer aided Design (CAD), computer aided manufacturing (CAM), computer aided testing (CAT) and computer aided engineering (CAE) development of the concepts and come.
EDA technology is on the computer as the tool, the designer in EDA software platform, with VHDL HDL finish design documents, then by the computer automatically logic compilation, reduction, division, comprehensive, optimization, layout and wiring and simulation for a particular goal chips, until the adapter compilation, logic mapping and programming download, etc.
1 EDA technology concepts
EDA technology is in electronic CAD technology developed on the basis of computer software system by means of computer for working platform, shirt-sleeve application of electronic technology, computer technology and information processing and intelligent technology to the latest achievements of electronic products, the automatic design.
Using EDA tools, electronic stylist can be from concept, algorithm, agreement, etc, begin to design your electronic system a lot work can be finished by computer and electronic products can be from circuit design, performance analysis to design the IC territory or PCB layout the whole process of the computer automatically complete the processing.
Now on the concept of using EDA or category very wide. Included in machinery, electronics, communication, aerospace, chemical, mineral, biology, medicine, military and other fields, have EDA applications. Current EDA technology has in big companies, enterprises, institutions and teaching research departments extensive use. For example in the aircraft manufacturing process, from design, performance testing and characteristic analysis until a flight simulator, all may involve EDA technology. Globalization-the EDA technology, mainly in electronic circuit design, PCB design and IC design.
EDA can be divided into system level and circuit-level and physical implementation level.
EDA是電子設(shè)計自動化(Electronic Design Automation)的縮寫,在20世紀90年代初從計算機輔助設(shè)計(CAD)、計算機輔助制造(CAM)、計算機輔助測試(CAT)和計算機輔助工程(CAE)的概念發(fā)展而來。
EDA技術(shù)就是以計算機為工具，設(shè)計者在EDA軟件平臺上，用硬件描述語言HDL完成設(shè)計文件，然后由計算機自動地完成邏輯編譯、化簡、分割、綜合、優(yōu)化、布局、布線和仿真，直至對于特定目標芯片的適配編譯、邏輯映射和編程下載等工作。
1 EDA技術(shù)的概念
EDA技術(shù)是在電子CAD技術(shù)基礎(chǔ)上發(fā)展起來的計算機軟件系統(tǒng)，是指以計算機為工作平臺，融合了應用電子技術(shù)、計算機技術(shù)、信息處理及智能化技術(shù)的最新成果，進行電子產(chǎn)品的自動設(shè)計。
利用EDA工具，電子設(shè)計師可以從概念、算法、協(xié)議等開始設(shè)計電子系統(tǒng)，大量工作可以通過計算機完成，并可以將電子產(chǎn)品從電路設(shè)計、性能分析到設(shè)計出IC版圖或PCB版圖的整個過程的計算機上自動處理完成。
現(xiàn)在對EDA的概念或范疇用得很寬。包括在機械、電子、通信、航空航天、化工、礦產(chǎn)、生物、醫(yī)學、軍事等各個領(lǐng)域，都有EDA的應用。目前EDA技術(shù)已在各大公司、企事業(yè)單位和科研教學部門廣泛使用。例如在飛機制造過程中，從設(shè)計、性能測試及特性分析直到飛行模擬，都可能涉及到EDA技術(shù)。本文所指的EDA技術(shù)，主要針對電子電路設(shè)計、PCB設(shè)計和IC設(shè)計。
EDA設(shè)計可分為系統(tǒng)級、電路級和物理實現(xiàn)級。
2 EDA常用軟件
EDA工具層出不窮，目前進入我國并具有廣泛影響的EDA軟件有：multiSIM7（原EWB的最新版本）、PSPICE、OrCAD、PCAD、Protel、Viewlogic、Mentor、Graphics、Synopsys、LSIIogic、Cadence、MicroSim等等。這些工具都有較強的功能，一般可用于幾個方面，例如很多軟件都可以進行電路設(shè)計與仿真，同進還可以進行PCB自動布局布線，可輸出多種網(wǎng)表文件與第三方軟件接口。
下面按主要功能或主要應用場合，分為電路設(shè)計與仿真工具、PCB設(shè)計軟件、IC設(shè)計軟件、PLD設(shè)計工具及其它EDA軟件，進行簡單介紹。
