ence, etc. These tools are strong function, generally can be used in several aspects, such as many software can undertake circuit design and simulation, with into and can be automatically PCB layout wiring, output various s list document with a third party software interface. According to the main function below or main applications, divided into circuit design and simulation tools, PCB design software, IC design software and PLD design tools and other EDA software, simple introduction. electronic circuit design and simulation tools We may have used test plate or other things has produced some electronic making to carry on the practice. But sometimes, we will find it to have a lot of questions, didn39。日本、韓國(guó)都有 ASIC 設(shè)計(jì)工具,但不對(duì)外開(kāi)放。有條件的企業(yè)可開(kāi)展“網(wǎng)絡(luò)制造”,便于合作設(shè)計(jì)、合作制造,參與國(guó)內(nèi)和國(guó)際競(jìng)爭(zhēng)。 從應(yīng)用領(lǐng)域來(lái)看, EDA 技術(shù)已經(jīng)滲透到各行各業(yè),如上文所說(shuō),包括在機(jī)械、電子、通信、航空航航天、化工、礦產(chǎn)、生物、醫(yī)學(xué)、軍事等各個(gè) 領(lǐng)域,都有EDA 應(yīng)用。 ③其它 EDA 軟件如專(zhuān)門(mén)用于微波電路設(shè)計(jì)和電力載波工具、 PCB 制作和工藝流程控制等領(lǐng)域的工具,在此就不作介紹了 。 ⑨ WSI:生產(chǎn) PSD(單片機(jī)可編程外圍芯片)產(chǎn)品。 ④ ACTEL:反熔絲(一次性燒寫(xiě)) PLD 的領(lǐng)導(dǎo)者。通常來(lái)說(shuō),在歐洲用 Xilinx的人多,在日本和亞太地區(qū)用 ALTERA 的人多,在美國(guó)則是平分秋色。下面介紹主要器件生產(chǎn)廠家和開(kāi)發(fā)工具。只不過(guò)是選擇不同公司的 SPICE,像 MiceoSim 的PSPICE、 Meta Soft 的 HSPICE 等等。隨著 FPGA 設(shè)計(jì)的規(guī)模越來(lái)越大,各EDA 公司又開(kāi)發(fā)了用于 FPGA 設(shè)計(jì)的綜合軟件,比較有名的有: Synopsys 的 FPGA Express, Cadence 的 Synplity, Mentor 的 Leonardo,這三家的 FPGA 綜合軟件占了市場(chǎng)的絕大部分。 Viewlogic 的仿真器有:viewsim 門(mén)級(jí)電路仿真器, speedwaveVHDL 仿真器, VCSverilog 仿真器。其它公司的軟件相對(duì)來(lái)說(shuō)使用者較少。 目前在我國(guó)用得最多當(dāng)屬 Protel,下面僅對(duì)此軟件作一介紹。MultiSIM7 還具 有 IV 分析儀(相當(dāng)于真實(shí)環(huán)境中的晶體管特性圖示儀)和Agilent 信號(hào)發(fā)生器、 Agilent 萬(wàn)用表、 Agilent 示波器和動(dòng)態(tài)邏輯平筆等。最新推出了 版本??諝鈩?dòng)力學(xué)方面的數(shù)據(jù)由資深專(zhuān)家提供,軟件開(kāi)發(fā)商是 IBM,飛行器設(shè)計(jì)工程師只需利用仿真軟件在計(jì)算機(jī)平臺(tái)上進(jìn)行各種仿真調(diào)試工作即可。但是有的時(shí)候,我們會(huì)發(fā)現(xiàn)做出來(lái)的東西有很多的問(wèn)題,事先并沒(méi)有想到,這樣一來(lái)就浪費(fèi)了我們的很多時(shí)間和物資。目前 EDA 技術(shù)已在各大公司、企事業(yè)單位和科 研教學(xué)部門(mén)廣泛使用。畢業(yè)設(shè)計(jì) (論文 )外文資料翻譯 系 : 信息工程系 專(zhuān) 業(yè): 電子信息工程 附 件: ; 指導(dǎo)教師評(píng)語(yǔ): 簽名: 年 月 日 注:請(qǐng)將該封面與附件裝訂成冊(cè)。例如在飛機(jī)制造過(guò)程中,從設(shè)計(jì)、性能測(cè)試及特性分析直到飛行模擬,都可能涉及到 EDA 技術(shù)。而 且增加了產(chǎn)品的開(kāi)發(fā)周期和延續(xù)了產(chǎn)品的上市時(shí)間從而使產(chǎn)品失去市場(chǎng)競(jìng)爭(zhēng)優(yōu)勢(shì)。同樣,他們其他的很多東西都是采用了這樣類(lèi)似的方法,從大到小,從復(fù)雜到簡(jiǎn)單,甚至 包括設(shè)計(jì)家具和作曲,只是具體軟件內(nèi)容不同。它可以進(jìn)行各種各樣的電路仿真、激勵(lì)建立、溫度與噪聲分析、模擬控制、波形輸出、數(shù)據(jù)輸出、并在同一窗口內(nèi)同時(shí)顯示模擬與數(shù)字的仿真結(jié)果。同時(shí)它還能進(jìn)行 VHDL 仿真和 Verilog HDL 仿真。 Protel 是 PROTEL(現(xiàn)為 Altium)公司在 20 世紀(jì) 80 年代末推出的 CAD 工具,是 PCB 設(shè)計(jì)者的首選軟件。中國(guó)華大公司也提供 ASIC 設(shè)計(jì)軟件(熊貓 2021);另外近來(lái)出名的 Avanti 公司,是原來(lái)在 Cadence 的幾個(gè)華人工程師創(chuàng)立的,他們的設(shè)計(jì)工具可以全面和 Cadence 公司的工具相抗衡,非常適用于深亞微米的 IC設(shè)計(jì)。 Mentor Graphics 有其子公司 Model Tech 出品的 VHDL 和 Verilog 雙仿真器: Model Sim。 ④布局和布線 在 IC 設(shè)計(jì)的布局布線工 具中, Cadence 軟件是比較強(qiáng)的,它有很多產(chǎn)品,用于標(biāo)準(zhǔn)單元、門(mén)陣列已可實(shí)現(xiàn)交互布線。 HSPICE 現(xiàn)在被 Avanti 公司收購(gòu)了。 ① ALTERA: 20 世紀(jì) 90 年代以后發(fā)展很快。全球PLD/FPGA 產(chǎn)品 60%以上是由 Altera 和 Xilinx 提供的。由于反熔絲 PLD 抗輻射、耐高低溫、功耗低、速度快,所以在軍品和宇航級(jí)上有較大優(yōu)勢(shì)。這是一種特殊的 PLD,如最新的 PSD8xx、 PSD9xx 集成了 PLD、 EPROM、 Flash,并支持 ISP(在線編程),集成度高,主要用于配合單片機(jī)工作。 EDA 的應(yīng)用 EDA 在教學(xué)、科研、產(chǎn)品設(shè)計(jì)與制造等各方面都發(fā)揮著巨大的作用。另外, EDA 軟件的功能日益強(qiáng)大,原來(lái)功能比較單一的軟件,現(xiàn)在增加了很多新用途。開(kāi)展“數(shù)控化”工程和“數(shù)字化”工程。中國(guó)華大集成電路設(shè)計(jì)中心,也提供 IC 設(shè)計(jì)軟件,但性能不是很強(qiáng)。t think, so they wasted a lot of our time and materials. And increases product development cycle and lasted product timetomarket transforms product lose market petitive advantage. Have to use DianLaoTie test plate can know the results of method? Conclusion there is, this is circuit design and simulation technology. Say to the electronic circuit design and simulation tools of this technology, without mentioning America, have to mention their plane design why has high efficiency. Before our finalize the design a mediumsized plane design from the draft to the detailed design to the wind tunnel test to finally gives a picture to the actual operation, the cycle is about to 10 years. The United States is 1 year. Why is there such a huge gap? Because America in the design most USES is the virtual simulation technology, and the years of accumulation of various wind tunnel test parameters input puter, then through puter programming pile a virtual environment of software, and make it can automatic gameponent related formula and call after longterm accumulated input puter related experience parameters. Thus, as long as the aircraft shape program data in the virtual wind tunnel test software, where unreasonable have changes there, until the best effect, the efficiency high, end as long as natural again in the actual environment test several times look for shortage can finalize the design, from their Boeing 747 to us F16 are using this method. Aerodynamically data by senior experts to provide, software developers is IBM, aircraft design engineer just using simulation software in puter platform of various simulative debugging can. Similarly, they many other things are adopted such similar method, from large to small, from plex to simple, even including the design of furniture and position, just specific software different contents. In fact, they invented the first generation of puters is this purpose (it is to efficient design artillery and related shells and other large amount of calculation of design). Electronic circuit design and simulation tools including SPICE/PSPICE。 Gate Ensemble Gate arrays wiring manometers。s develops very quickly. The main products are: MAX3000/7000, FELX6K / 10K, APEX20K, ACEX1K, Stratix etc. Its development tools MAX + PLUS II is more successful PLD development platform, the latest again launched Quartus II development software. Altera pany provides more forms of design input method, binding thirdparty VHDL prehensive tools, such as: integrated software FPGA Express, such ModelSim Leonard, simulation software. (2)the inventor of the ILINX: FPGA. Product categories with plete, basically have: XC9500/4000, Coolrunner (XPLA3), Spartan, Vertex etc series, its biggest Vertex II Pro device has reached eight million door. Develop software for the Foundation and ISE. Generally speaking, people in Europe with Xilinx, in Japan and the asiapacific region, with ALTERA more people in the United States i
