It offers a single, easy-to-use graphical interface for all your design needs后加工的特点和无缝连接的印刷电路板设计包，比如来自电子学的工作台的印刷电路板绘制，他提供了一个简单的，易于使用的绘画界面来让你做你需要的设计Multisim 2001 provides all the advanced functionality you need to take designs from specification to production. And because the program tightly integrates schematic capture, simulation, Printed Circuit Board (PCB) layout and programmable logic, you can design with confidence, knowing that you are free from the integration issues often found when exchanging data between applications from different vendorsMultisim 2001提供了所有从说明书到产品你设计需要的先进的功能，而且因为这些程序是一体化获取的，仿真，印刷电路板规划和可编程逻辑。你知道你设计是很自由的，因为综合结果通常可以被不同的卖主应用与数据交换，所以你在设计时很自信 About the Circuit Design Process（电路设计过程）Multisim 2001 supports every step of the overall circuit design process, which typically includes the following phasesMultisim 2001支持总电路设计的每一步，包括下面这些代表性的阶段1. Entering the design (using schematic capture, behavioral language formats or other methods) into the software tool being used.进入设计（使用按钮，机器语言方法或者其他方法）进入要使用的软件工具2. Verifying that the behavior of the circuit matches expectations. This step is performed using simulation, and analysis.验证电路是否匹配期望值，这一步由仿真和分析来实现3. Modifying the circuit design if the behavior does meet expectations, and returning to step 2 as often as necessary.修改电路，如果结果不符合期望值，需要返回步骤24. 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.不管怎样，使用的电路是个物理工具，要经过适当的设计过程，比如，如果要印刷在印刷电路板上，那下一步是使用印刷电路板去规划设计出好象电子学工作台上的印刷电路板绘制产品，如果要设计在可编程逻辑器件上（比如PLD，CPLD，FPGA），那下一步是使用如电子学工作台上要用的合成工具一样的工具 Multisim 2001 Features Summary（特点概要）Module（模块） Personal edition （个人版本） Professional Edition（专业版本） Power Professional Edition（权威版本）Basic Schematic Capture(常用按钮)xxxInteractive Simulation（交互仿真）xxxSymbol Editor（符号编辑器）xxxEda PARTS（电子设计自动化零件）xxxSPICE Analog/Digital Simulation（模拟/数字仿真调节）xxxEditable Footprint Field（可编辑已用领域）xxxElectro-mechanical Components（机电元件）xxxDC Operating Point Analysis（直流点分析）xxxAC Analysis（交流分析）xxxTransient Analysis（瞬时分析）xxxFourier Analysis（傅立叶分析）xxxNoise Analysis（噪声分析）xxxDistortion Analysis（失真分析）xxxDC Sweep Analysis（直流扫描分析）xxxAC and DC Sensitivity Analysis（交流和直流灵敏度分析）xxxVirtual Instruments（虚拟元件）8911Component Database and Editor（元件数据库和编辑器）standard, with 6,000 parts（含6000零件的规格）standard, with 12,000 parts（含12000零件的规格） advanced, with 16,000 parts（含16000零件的先进规格）Model Expansion Package（模板扩充包）xOptional（可选择的）xSPICE Import（调节输入）xxDistortion Analysis Instrument（失真分析工具）xxVirtual Wiring（虚拟配线）xxMenu-driven Simulation from Netlist 网页目录上的可用分析菜单(without schematic)非按钮xxMultiple Circuit Windows（倍增电路窗口）xxParameter Sweep Analysis（瞬时参量分析）xxTemperature Sweep Analysis（瞬时温度分析）xxPole Zero Analysis（零点分析）xxTransfer Function Analysis（转移函数分析）xxWorst Case Analysis）（最坏情况分析）xxMonte Carlo Analysis（蒙特卡罗法分析）xxTrace Width Analysis（痕量广度分析）xxComponent Search Engine（元件搜索引擎）standardadvanced（高级标准）Bill of Material（材料清单）standard advanced（高级标准）VHDLoptionaldesign/debug and simulation（可选择的设计/调试和仿真）Verilog HDLoptional（随意）optionalVHDL Synthesis（VHDL综合）optionaloptionalNoise Figure Analysis（噪声系数分析）xxProject/Team Design Module（项目/组设计模块）optionalxRF Module（射频无线电模块）optionalxAnalog & Digital Model Makers（模拟/数字模块制作）optionalxCode Modeling（代码建模）xPostprocessor（快速处理器）xBatched Analysis（群处理）xUser Defined Analysis（使用定义分析）xPSpice Import（可调输入）xxNetwork version（网络翻译）xxIntroduction to the Multisim Interface（multisim界面介绍） Multisim user interface consists of the following basic elements（multisim用户使用界面包括以下部分）Note（注释）Your circuit window may, by default, have a black background; however, for the purposes of this document, we show a white background. To change the background color, see The Circuit Tab. 你可能使用到的不在界面上的电路窗口是黑背景，然而，我们常常在文档下使用白背景去替代黑背景好看清楚电路标号 are, as in all Windows applications, where you find commands for all functions.在窗口应用程序里，你可以用寻找命令找到所有的功能The system toolbar contains buttons for commonly-performed functions, as described in System Toolbar and Zoom Toolbar Buttons.系统工具栏包括经常使用的功能的按钮，象描述和放大工具栏按钮The toolbar contains buttons for each instrument, as described in Introduction to the Multisim Instruments.在工具栏里包括每个元件的按钮，比如对multisim工具进行介绍的按钮The link to .com launches your Web browser loaded with the Electronic Workbench E Web site.

The Design Bar guides you through the logical steps of building, simulating, analyzing and, eventually, exporting your design. Although Design Bar functions are available from conventional menus, this manual assumes you are taking advantage of the ease of use offered by the Design Bar.设计工具栏是multisim的重要组成部分，使你可以很容易的使用提供的复杂功能，工具栏指导你合理的建造，模拟，分析，并且最终得到你的设计，本手册是在假定你是充分使用提供的工具栏的前提下说明的，尽管工具栏的功能对传统菜单的使用也很好 Component Design Bar Button（设计的元件按钮）The Component design button is selected by default, since the first logical activity is to place components on the circuit window. For details on the functions associated with this button, see Components.因为放置电路窗口里的元件是首先的逻辑行为，所以设计的元件按钮是缺省的。关于相关按钮的功能可以在元件中查看 Component Editing Design Bar Button（设计的元件编辑按钮）The Component Editing button lets you modify the components in Multisim, or add components. For details on the functions associated with this button, see Component Editing.设计的元件编辑按钮可以让你在multisim中修改和增加元件，关于相关按钮的功能你可以在可编辑元件中查看 Instruments Design Bar Button （设计的工具按钮） The Instrument design button is selected by default and lets you attach instruments to your circuit. For details on the functions associated with this button, see Instruments.设计的工具按钮是缺省设置的，你可以把工具放到你的电路设计中，关于相关按钮的功能你可以在工具中查看 Simulate Design Bar Button（仿真按钮）The Simulate button runs/pauses/stops the simulation. The green sine wave line moves while simulation is running. For details on functions associated with simulation, see Simulation.仿真按钮可以运行，暂停和停止仿真，当仿真进行时，绿色的正弦波同时运行，关于相关按钮的功能你可以在仿真中查看 Analysis Design Bar Button（分析按钮）The Analysis button lets you choose the analysis you want to perform on your circuit. For details on the functions associated with this button, see Analyses.分析按钮让你对电路进行你想要的分析，关于相关按钮的功能你可以在分析中查看 Postprocessor Design Bar Button（快速处理按钮）The Postprocessor button lets you perform further operations on the results of your simulation.

For details on the functions associated with this button, see Transfer/Communication.传递按钮可以让你连接并输出印刷电路板的规划项目，比如在电子学工作台的印刷电路板绘制，同样可以得到数字CAD和表格的程序编辑。关于相关按钮的功能你可以在传递/连接中查看 About Customizing the Interface（关于界面自定义）You can customize virtually any aspect of the Multisim interface, including the toolbars, the colors used in your circuit, page size, zoom level, auto-backup interval, symbol set (ANSI or DIN) and printer setup. 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.你可以将multisim界面中的任何方面自定义，包括工具栏，电路颜色，纸张大小，缩放比例，自动备份支持，符号设置（美国国家标准化组织或的国工业标准感光片感光度单位）和打印机设置，你的自定义设置保留了你使用的电路文件的个性化地方，比如，在某电路中用这个颜色而在其他电路中使用其他的颜色。你也可以不考虑个性化设置（比如，在某个细节将元件从红色改为黄色）或将整个电路一起改变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. 大多数自定义设置是通过选项和参数设置实现的，该命令可以使你只改变已经存在的电流回路设置或者改变已经存在和你将要创建的电流回路设置。比如，如果你的电流回路显示了元件标签并且你缺省保存了这些设置，当你选择File/New按钮创建新的电路时，该电路会显示元件标签。改变缺省设置会改变你已经创建和保存的电路。然而，如果你的电流回路显示了元件标签并且你只不过是隐藏了这些标签，那么该设置只影响你的电流回路Customization changes done through the pop-up menu, as described in the following sections, affect the current circuit only.弹出菜单，在下面选项进行自定义设置，只影响电流回路 General Instructions for Customizing the Interface Using the Preferences Screen（ 在参数选择屏上进行界面自定义的宏命令）This section explains general procedures for setting preferences.

It is important that you set passwords immediately when using restrictions that you want to keep secure against any modification by other users. The password for global restrictions is encrypted and stored in the Multisim program file. The password for circuit restrictions (for restricting only a particular circuit) is encrypted and stored in the circuit file. 通过密码保护全局限制和电路级限制，确保只有你才能设置或修改限制，当你使用限制去防止其他使用者做修改，可以设置密码，这是很重要的。全局限制的密码是加密并保存在multisim文件夹的。电路级限制的密码（只针对特定电路）是加密和并保存在电路文件夹的Setting Global Restrictions（设置全局限制）Use global restrictions to set the basic level of functionality of Multisim available to other users in all circuits with which they will work. You can select a default path where circuits are to be saved, hide databases, Parts Bins and the In Use list, and determine whether other users may edit components or place instruments. You can also choose which analyses will be available to other users to run.使用全局限制是对其他用户运行电路的整体multisim 可用功能做基本设置。你可以选择电路保存路径为缺省保存，隐藏数据库，零件集和“在使用中”菜单，并且确定是否其他用户可以编辑元件或替换工具。你能选择分析其他用户的有用运行。Note Global restrictions are overridden by circuit restrictions if the circuit restrictions are saved. See Setting Circuit Restrictions for information.注释 如果电路级限制被保存，那么全局限制将被它覆盖。内容查看电路级限制 To set general global restrictions:（设置常用的全局限制）1. Choose Options/Global restrictions.

From the Global restrictions screen, click the Analyses tab:在全局限制屏幕，点击分析面板2.Enable the desired analyses by clicking the appropriate check boxes (for more information on analyses, see Analyses), and click OK. Only the analyses you check will be enabled on the Simulate/Analyses menu or when the user clicks the Analyses design bar button.点击适合的检查框运行需要的分析（关于分析的更多资料，参看Analyses），再点击OK。你需要验证的分析在Simulate/Analyses菜单或直接点击分析设置按钮These options are immediately set for all circuits, unless you have set circuit restrictions. (See Setting Circuit Restrictions.)除非你设置了电路级限制，不然你设置的对所有电路都有效（参看电路级限制的设置） Setting Circuit Restrictions（设置电路级限制）Use circuit restrictions to set restrictions on individual circuits. Circuit restrictions override global restrictions. They are saved with your circuit and invoked each time the circuit is loaded. In addition to hiding Parts Bins and databases and setting available analyses, you can set a schematic to be read-only, i.e. not editable by other users, you can hide components?values, faults and uses in analyses, and you can lock subcircuits to make them unavailable for opening by other users.电路级限制的设置对单个电路有效。电路级限制覆盖全局限制。他们随电路一起保存和出现。除了零件集，数据库和设置有用分析的隐藏外，你还能设置为只读形式，即不能被其他用户编辑，你能隐藏元件的数值，故障和在分析中的用途，你还能锁住支电路，使其他用户不能打开Note Remember that circuit restrictions only apply to the current circuit; i.e. when you create a new circuit, only the global restrictions will apply (see Setting Global Restrictions for details). If you want circuit restrictions to apply to a new circuit, you will need to re-set those restrictions each time you create a new circuit. 注释 记得, 电路级限制只适用于电流回路。即当您创造一条新电路, 只有全局性限制将适用(细节参见设置全局性限制)。如果您要电路限制适用于一条新电路, 您将需要每创造一条新电路重新设置一次那些限制。 To set general cir
