Entering the design (using schematic capture, behavioral language formats or other methods) into the software tool being used. 進(jìn)入設(shè)計(jì)（使用按鈕，機(jī)器語言方法或者其他方法）進(jìn)入要使用的軟件工具 2. Verifying that the behavior of the circuit matches expectations. This step is performed using simulation, and analysis. 驗(yàn)證電路是否匹配期望值，這一步由仿真和分析來實(shí)現(xiàn) 3. Modifying the circuit design if the behavior does meet expectations, and returning to step 2 as often as necessary. 修改電路，如果結(jié)果不符合期望值，需要返回步驟2 4. Depending on how the circuit is to be physically implemented, passing the design through the appropriate process. For example, if it is to be placed on a PCB, the next step is to use a PCB layout program such as If it is to be placed on a programmable logic device (PLD, CPLD, FPGA, etc.), the next step is to use a synthesis tool such as that available from Electronics Workbench. 不管怎樣，使用的電路是個物理工具，要經(jīng)過適當(dāng)?shù)脑O(shè)計(jì)過程，比如，如果要印刷在印刷電路板上，那下一步是使用印刷電路板去規(guī)劃設(shè)計(jì)出好象電子學(xué)工作臺上的印刷電路板繪制產(chǎn)品，如果要設(shè)計(jì)在可編程邏輯器件上（比如PLD，CPLD，F(xiàn)PGA），那下一步是使用如電子學(xué)工作臺上要用的合成工具一樣的工具 Multisim 2001 Features Summary（特點(diǎn)概要） Module（模塊） Personal edition （個人版本） Professional Edition（專業(yè)版本） Power Professional Edition（權(quán)威版本） Basic Schematic Capture(常用按鈕) x x x Interactive Simulation（交互仿真） x x x Symbol Editor（符號編輯器） x x x Eda PARTS（電子設(shè)計(jì)自動化零件） x x x SPICE Analog/Digital Simulation（模擬/數(shù)字仿真調(diào)節(jié)） x x x Editable Footprint Field（可編輯已用領(lǐng)域） x x x Electro-mechanical Components（機(jī)電元件） x x x DC Operating Point Analysis（直流點(diǎn)分析） x x x AC Analysis （交流分析）x x x` Transient Analysis （瞬時分析）x x x Fourier Analysis（傅立葉分析） x x x Noise Analysis（噪聲分析） x x x Distortion Analysis（失真分析） x x x DC Sweep Analysis（直流掃描分析） x x x AC and DC Sensitivity Analysis （交流和直流靈敏度分析）x x x Virtual Instruments（虛擬元件） 8 9 11 Component Database and Editor（元件數(shù)據(jù)庫和編輯器） standard, with 6,000 parts（含6000零件的規(guī)格） standard, with 12,000 parts（含12000零件的規(guī)格） advanced, with 16,000 parts（含16000零件的先進(jìn)規(guī)格） Model Expansion Package（模板擴(kuò)充包） x Optional （可選擇的）x SPICE Import （調(diào)節(jié)輸入） x x Distortion Analysis Instrument （失真分析工具） x x Virtual Wiring （虛擬配線） x x Menu-driven Simulation from Netlist 網(wǎng)頁目錄上的可用分析菜單(without schematic) 非按鈕 x x Multiple Circuit Windows（倍增電路窗口） x x Parameter Sweep Analysis （瞬時參量分析） x x Temperature Sweep Analysis （瞬時溫度分析） x x Pole Zero Analysis （零點(diǎn)分析） x x Transfer Function Analysis （轉(zhuǎn)移函數(shù)分析） x x Worst Case Analysis）（最壞情況分析） x x Monte Carlo Analysis（蒙特卡羅法分析） x x Trace Width Analysis （痕量廣度分析） x x Component Search Engine （元件搜索引擎） standard advanced（高級標(biāo)準(zhǔn)） Bill of Material（材料清單） standard advanced（高級標(biāo)準(zhǔn)） VHDL optional design/debug and simulation（可選擇的設(shè)計(jì)/調(diào)試和仿真） Verilog HDL optional（隨意） optional VHDL Synthesis（VHDL綜合） optional optional Noise Figure Analysis （噪聲系數(shù)分析） x x Project/Team Design Module （項(xiàng)目/組設(shè)計(jì)模塊） optional x RF Module（射頻無線電模塊） optional x Analog & Digital Model Makers （模擬/數(shù)字模塊制作） optional x Code Modeling（代碼建模） x Postprocessor （快速處理器） x Batched Analysis （群處理） x User Defined Analysis （使用定義分析） x PSpice Import（可調(diào)輸入） x x Network version （網(wǎng)絡(luò)翻譯） x x Introduction to the Multisim Interface（multisim界面介紹） Multisim user interface consists of the following basic elements（multisim用戶使用界面包括以下部分） Note（注釋） Your circuit window may, by default, have a black background; however, for the purposes of this document, we show a white background.

Your customization settings are saved individually with each circuit file you use so you could, for example, have one color scheme for one circuit and another for a different circuit. You can also override the settings for individual instances (for example, change one particular component from red to orange) or for the entire circuit. 你可以將multisim界面中的任何方面自定義，包括工具欄，電路顏色，紙張大小，縮放比例，自動備份支持，符號設(shè)置（美國國家標(biāo)準(zhǔn)化組織或的國工業(yè)標(biāo)準(zhǔn)感光片感光度單位）和打印機(jī)設(shè)置，你的自定義設(shè)置保留了你使用的電路文件的個性化地方，比如，在某電路中用這個顏色而在其他電路中使用其他的顏色。你也可以不考慮個性化設(shè)置（比如，在某個細(xì)節(jié)將元件從紅色改為黃色）或?qū)⒄麄€電路一起改變 Most customization is done through Options/Preferences. This command allows you to either change the settings for the current circuit file only, or create default settings that affect both the current circuit and all circuits you subsequently create. For example, if your current circuit shows component labels and you save those settings as the default, when you choose File/New and create a new circuit, that circuit will be set to show component labels as well. Changing the default settings will affect circuits you have already created and saved. However, if your current circuit shows component labels and you simply change it to hide such labels, the change affects only your current circuit. 大多數(shù)自定義設(shè)置是通過選項(xiàng)和參數(shù)設(shè)置實(shí)現(xiàn)的，該命令可以使你只改變已經(jīng)存在的電流回路設(shè)置或者改變已經(jīng)存在和你將要創(chuàng)建的電流回路設(shè)置。比如，如果你的電流回路顯示了元件標(biāo)簽并且你缺省保存了這些設(shè)置，當(dāng)你選擇File/New按鈕創(chuàng)建新的電路時，該電路會顯示元件標(biāo)簽。改變?nèi)笔≡O(shè)置會改變你已經(jīng)創(chuàng)建和保存的電路。然而，如果你的電流回路顯示了元件標(biāo)簽并且你只不過是隱藏了這些標(biāo)簽，那么該設(shè)置只影響你的電流回路 Customization changes done through the pop-up menu, as described in the following sections, affect the current circuit only. 彈出菜單，在下面選項(xiàng)進(jìn)行自定義設(shè)置，只影響電流回路 General Instructions for Customizing the Interface Using the Preferences Screen （ 在參數(shù)選擇屏上進(jìn)行界面自定義的宏命令） This section explains general procedures for setting preferences.
