EDA technology and software 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 b
