1、英文翻译 届 电子信息工程 专业 班级姓 名 学 号 指导教师 二一 六 年 三 月 十 日EDA的发展及VHDL的应用 90s in 20 centuries, international last electronics and calculator technique more the forerunners nation, has been being actively investigating a new design method of the electronics electric circuit, and carried on an exhaustive change in

2、 the aspects of designing a method, tool wait, obtain huge success.At the design realm of the electronics technique, the application of programmable logic spare part(like CPLD, FPGA), have already got extensive universality, these spare parts brought tremendous vivid for the design of numerical syst

3、em.These spare parts can pass a software plait a distance but as to its hardware structure and work the way carry on heavy Gou and make thus the design of hardware can like software design so convenient fast.The all these biggest changed a traditional numerical method, design process of the system d

4、esign and design idea and promoted the EDA technical quick development. The EDA is an electronics design automation(the Automation of the Electronic Design) of abbreviation, design(CAD) from the calculator assistance at the beginning of 90s in 20 centuries, calculator assistance manufacturing(CAM),

5、calculator assistance test(CAT) and calculator lend support to the concept of engineering(CAE) a development since then.The EDA technique is to take calculator as tool, design at EDA software terrace up, use the hardware description language HDL completion a design a document, then is of oneself com

6、pleted logic to edit and translate, turn Chien, partitioned by the calculator, comprehensive, excellent turn, set up, cloth line with imitate really, until for particular target chip of proper go together with to edit and translate, the logic reflect to shoot with plait distance download etc. work.T

7、he EDA technical emergence, biggest raised efficiency and maneuverability of electric circuit design, eased to design of labor strength. These spare parts can pass a software plait a distance but as to its hardware structure and work the way carry on heavy Gou and make thus the design of hardware ca

8、n like software design so convenient fast.The all these biggest changed a traditional numerical method, design process of the system design and design idea and promoted the EDA technical quick development.Make use of EDA tool, the electronics designer can start design electronics system from the con

9、cept, calculate way, agreement.etc., a great deal of work can pass calculator completion, and can design the electronics product is from the electric circuit, the function analyze compute of the whole process of design an IC landscape or PCB landscape on board auto processing completion. Use to the

10、EDA concept or category very breadth now.Include in each realm of the machine, electronics, correspondence, aviation aerospace, chemical engineering, mineral, living creature, medical science, military.etc., all there is EDA application.The EDA technique has already extensively used in each archduke

11、 department, the Qi business unit and research teaching section currently.For example in the airplane the manufacturing the process, from design, performance test and characteristic analytical until fly emulation, may involve an EDA technique.The EDA technique that this text point mainly to the desi

12、gn, PCB design of the electronics electric circuit and IC design. The EDA design can is divided into system class, electric circuit class and physics to carry out class. The EDA in common use software:The EDA tool pile up one after another and get into an our country currently and have the EDA softw

13、are of extensive influence to have:MultiSIM 7(the latest edition of original EWB), PSPICE, OrCAD, PCAD, Protel, Viewlogic, Mentor, Graphics, Synopsys, LSIIogic, Cadence, MicroSim, ISE, modelsim etc.These tools all have stronger function, generally can used for a few aspects, for example a lot of sof

14、twares all can carry on an electric circuit design with imitate really, together entering can also carry on PCB to automatically set up cloth line, can output various net form a document with the third square software connect. The VHDL English full name be the HardwareDescription Language of the Int

15、egrated Circuit of the Very-High-Speed, birth in 1982.At the end of 1987, the VHDL is confirm by IEEE and American Ministry of National Defense to describe language for the standard hardware.Announced VHDL standard edition from the IEEE, IEEE-1076(call 87 versions) after, the each EDA company releas

16、ed own VHDL design environment one after another, or declared that the own design tool can connect with VHDL.Henceforth the VHDL designed realm to get to extensively accept in the electronics, and gradually replaced an originally not- standard hardware description language.In 1993, the IEEE carried on to revise to the VHDL, describe ability to up expand a VHDL contents from high
