无 锡 职 业 技 术 学 院毕业设计说明书（英文翻译）英文The development trend of EDA techniqueFace the electronics product that flies to soon develop nowadays market, the designer needs more practical and fast EDA tool and uses an unified integration to turn to design environment, changes tradition design way of thinking and concentrates the energy to the design to conceive outline, project comparison and look for excellent turn aspects like designed, need with the quickest speed, develop an electronics product with good function and top-grade quality, put forward higher request to the EDA technique. The future EDA technique will obtain new breakthrough in the aspects of imitating really, cycle time analyzing, integrated circuit being automatic to test, high-speed PC board designing and developing operating expanding of platform etc., the facing function is strong, in brief easy to learn, use a convenient direction development. For satisfying thousand design request that ten thousand another system customers put forward of differing, the best way is designed chip by himselfherself by the customer, let they think that the electric circuit that design directly designs on own appropriation chip. Micro-electronics the technical development, the development of especially programmable logic spare part, make micro-electronics factory the programmable logic spare part that can provide various scale for the customer in the house, make design pass to design chip to carry out electronics system function. The development of EDA tool provides the whole line the EDA tool for designer again. This stage development gets up of EDA tool, the purpose expects before designing what designer was engaged in many high times designing is completed by tool, if can request the customer to convert into to design a technical specification, effective of the antinomy of processing available design resources and ideal design target, press concrete of hardware, software and calculate way resolve a design etc.Because of the development of electronics technique and EDA tool, the designer can be not too growing of time inside use EDA tool, pass some designs processes that in brief standardize, make use of the micro-electronics factory designs database for providing in the house to complete tens of thousands ASIC and the design and verifications of integration system.The programmable logic spare part is already comes enriching the semi-conductor sparing part of attraction most in the world nowadays and design in the modern electronics system in play a more and more important role. Past several years inside, the growth of programmable spare part market mainly comes from big capacity of programmable logic spare part CPLD and FPGA; its future development trend is as follows:(1)Take a direction development toward the high definition, high speed degree and broadbandDuring the development of the electronics system, the engineers system design principle wants to be subjected to the restriction of electronics spare part that he/she can choose, while the development of spare part promoted the renewal of design method again. Along with the exaltation of electronics system complications, the high definition, high speed degree and the programmable logic product that broadband take have already become an essential spare part, its scale also continuously extends, from at the beginning several hundreds of till now of ascend 1,000,000, some ability that the last system hashing already had a slice integrates. The emergence of the programmable logic spare part of this high definition, big capacity brought design and realization of modern electronics system (complicated system) a huge help. Design method and design efficiency leap and brought the huge need of spare part, this need urges the spare part to produce a progressing unremittingly of craft again, but each time the improvement of craft, the scales of programmable logic spare part will expand very greatly.(2)To develop in the system programmable directionIt is programmable to refer to the ability that the procedure (or calculate way) still has to change its internal function after placing into a customer system in the system. Adoption at system programmable technique can be like to treat software to so pass to weave distance to install the function of hardware inside the system, lead into the all new concept of soft hardware in the electronics system thus. It not only make the design of the electronics system and the improvement and enlargement of the product function become very simple, also make new generation electronics the system have the strongest vivid and adaptability, were the realization that many processing of complicated signals and information process to provide a new way of thinking and method.(3)To can predict while postponing direction developmentIn the current number system, because of data processing quantity of surge, request it to have the big data swallows to vomit quantity and add of multimedia technique of quick development, request to the picture carry on solid processing, will beg the system hardware of having the high speed system. For promising the stability of high-speed system, postponing of programmable logic spare part can predict that sex is very important. Customer at carry on system heavy reach at the same time, what to worry is to postpone characteristic meeting cant because of afresh cloth line but change, while postponing the change of characteristic will cause heavy reach system of not dependable, this to high speed of number system but speech is very terrible. Therefore, for adapting to in the future the request of complicated and high-speed electronics system, the high speed of the programmable logic spare part can predict being very necessary while postponing.(4)To hybrid the programmable technique direction developThe programmable logic spare part brings tremendous convenience for the development of electronics product, its extensive application makes composing and design method of electronics system all take place very big variety. But, research and development of relevant programmable spare part work majority all concentrated at number logic electric circuit up, until in November, 1999, the Lattice company released programmable emulation electric circuit at the system and expanded vaster prospect for EDA technical application. It allows to design the use development software designs in the calculator, modification imitate electric circuit, carry on electric circuit characteristic to imitate really, finally passing to weave distance electric cable will design a project to download into chip. There has been the research that several companies develop this aspect, and emulation and number releasing respectively mix the programmable spare part of type, believe in the future for several years in, imitating electric circuit and few molds to mix the programmable technique of electric circuit will get a larger development.(5)Consume an aspect development toward the low electric voltage, low achievementIntegrate a flying of technique to soon develop, craft level of continuously exaltation, economize on energy currents rise in the whole world, also put forward for the semi-conductor industry to lower work electric voltage and lower achievement consume of direction development.1. The EDA technique will extensively be applied to electricity professional fulfillment teaching in high school to work to winVarious number integrated circuit chips, using the VHDL language can carry on a convenient description, can be a standard component to carry on adjusting to use after born component. At the same time, ask for help from VHDL development design platform, can carry on the function of system to imitate to really imitate with cycle time really, asking for help from an experiment development the system can carry on hardware function to verify etc., as a result can consumedly simplify a number electronics technical experiment, and can be free from to restrainedly develop various experiment according to the students design.For electronics technique course design, especially number systematic topic, dont need to add any new thing at the EDA laboratory, canning immediately design a various more complicated number system, and ask for help from an experiment development the system can expediently carry on a hardware verification, such as design the frequency account, transportation control light, and stop-watch.etc.From 1997 whole country the third electronics technique design contest adoption FPGA|CPLD spare part, FPGA|CPLD have already got more and more exploitations of contestants, and give settle of topic if dont ask for help from FPGA |the CPLD spare part probably can not carry out at all. Therefore the EDA technique will become the basic technical ability that various electronics technique design contest contestant has to control and overcome of magic weapon.The design of modern electronics product cans not get away from an EDA technique, as a professional electricity graduate student, ask for help from EDA technique at graduate design in can quickly and design the electronics system of various high performances, and carry out, modify very easily and perfect.During the period of the whole university study, we can divide the stage, layering times ground carries on technical study of EDA and application to the professional student of electricity and makes them quickly control also the effect make use of this new technique, the fulfillment that can also consumedly raise a student at the same time begins ability, creative ability and calculator applied ability.2. The EDA technique will extensively be applied to the development of the research work and the new product inBecause the programmable logic spare part function price compares continuously to raise and develop software function of continuously perfect, the way design that the EDA technique designs electronics system to have to use software hardware; Design process in can use to carry on concerning the software various imitate really; The system can weave a distance on the scene, on-line get stripe; The whole system can integrate in the exploitation of a chip first-class characteristics, it will extensively be applied to the development work of the research work and the new product in.3. The EDA technique will extensively be applied to the development of appropriation integrated circuitThe programmable spare part manufactory house can be mass-produced with in general use spare part according to the certain specification, the customer can press the in general use spare part to buy from select in the market, then press own request to pass to weave the function that the distance carries out appropriation integrated circuit. Therefore, make technique and forerunner in the worlds integrated circuit manufacturing technique to still have a certain margin to the integrated circuit of our country, develop the appropriation integrated circuit of having the independent intelligent property right, and have become the important task of related professional personnel.The physical realization means to use the design that the actual spare part carries out number system and uses whether the electric circuit that the gauge diagraph designs meets a design request. The number system in nowadays usually adopts large-scale and super large scale integration, because of spare part integration degree Ago, lead line intensively, past generally after the electric circuit designs to complete namely design PC board, assemble electric circuit to carry on a test on the PC board. Need to be advertent BE, the physical characteristic of PC board will also influence the logic relation of electric circuit.4. The EDA technique will extensively be applied to a getting stripe of traditional machine electricity equipments to change generation and technique reformationThe electricity of the traditional machine electricity equipments controls system, if makes use of an EDA technique to carry on afresh design or carry on a technique reformation, not only design a period short, design the cost is low, and will raise the function of product or equipments, narrow a product physical volume, raise the technique content of product, raise the additional value of product.Face the electronics product that flies to soon develop nowadays market, the electronics design personnel needs more practical and fast EDA tool and uses an unified integration to turn to design environment and changes tradition design way of thinking, then have the initiative to consider that the concrete physics carries out a way, but the energy concentrate a design to conceive outline, project comparison with look for excellent turn aspects like designed, develop an electronics with good function and top-grade quality with the quickest speed of product.
