Chapter1Educators’ GuideIn addition to the many features that have made Multisim a favorite with professional users,there are also a number of education-specific features that are outlined in this guide.This chapter describes the tools that Multisim offers to let you exercise greater control overthe program’s interface and functionality when sharing circuits with students, as well as to setcertain aspects of a circuit’s behavior for instructional purposes. These features includeassigning faults to components in a circuit and setting global and circuit restrictions.Some of the features described in this chapter may not be available in your edition ofMultisim 8. Refer to the release notes for a description of the features available in youredition.The following are described in this chapter.1.1SubjectPage No.Circuit Creator’s Name1-1Assigning Faults to Components1-2Using Restrictions1-4Link to Education Resources1-13Circuit Creator’s NameMultisim provides a feature by which the name of the creator of each circuit is stored with thatcircuit. Educators can take advantage of this feature to identify the student who, for example,created the circuit being submitted as the answer to an assignment (provided that the studentuses his/her own copy of the program to create the circuit). The name appears on the CircuitRestrictions dialog box, which you can view as long as no passwords have been set — see“1.3.2 Setting Circuit Restrictions” on page 1-9 for more information.Multisim 8 for Educators1-1

Educators’ Guide1.2Assigning Faults to ComponentsYou may want to assign faults to components for instructional purposes, such astroubleshooting exercises. You can manually assign faults to individual components in acircuit or let Multisim randomly assign faults to various components across a circuit.1.2.1Setting a Placed Component’s FaultsYou can assign a fault to any terminal of the placed component using the Fault tab of thatcomponent’s properties dialog box. To assign a fault to a placed component:1. Double-click on the component. The component’s properties dialog box appears.2. Click the Fault tab:Shows the terminalsof the placedcomponent — variesdepending oncomponent type.Choose whichtype of fault toassign to theselected terminalsNote Refer to the Multisim 8 User Guide for information on the other tabs in the abovedialog box.3. Select the terminals to which the fault should apply.1-2Electronics Workbench

Assigning Faults to Components4. Enable the type of fault you want assigned to a terminal. The options are:OptionDescriptionNoneNo fault.OpenAssigns a very high resistance to the terminal, as if the wire leading to theterminals was broken.ShortAssigns a very low resistance to the terminal, so the component has nomeasurable affect on the circuit.LeakageAssigns the resistance value specified in the fields below the option, inparallel with the selected terminals. This causes the current to leak past theterminals instead of going through them.5. To cancel your changes, click Cancel. To save your changes, click OK.1.2.2Using the Auto Fault OptionNote This function is hidden when the simplified version option is selected. For details, see“1.3.1.2 Simplified Version” on page 1-6.When you use the Auto Fault option, you specify the number of any type of fault or,optionally, the number of faults per different type of fault, that you want Multisim to assign toplaced components in the circuit. To use the auto fault option:1. Choose Simulate/Auto Fault Option. The Auto Fault dialog box appears:Note The Auto Fault option is disabled until a component is placed on the workspace.Multisim 8 for Educators1-3

Educators’ Guide2. Use the up/down arrow keys or enter numerical values directly in the Short, Open, andLeak fields, or enter a numerical value in the Any field to let Multisim randomly select thetype of faults to assign (in the quantity entered).3. If you specify a number of leaks, enter a number and unit of measurement in theSpecify Leak Resistance fields.4. Click OK to apply the faults, or Cancel to cancel, and return to the circuit window.1.3Using RestrictionsRestrictions are useful in a number of ways: when you are designing circuits for demonstration purposes and want to limit thefunctionality available to students when you are sharing circuits with students and want: to prevent them from being able to edit the circuit in any way to limit the types of modifications they can make to a circuit to limit the types of analyses they can perform on it to limit the information they can see about certain parts of the circuit (for example, thevalue of a resistor you want them to calculate).You can set global-level restrictions, which become default Multisim settings, or circuit-levelrestrictions, which affect only specific circuits.To ensure that only you can set or modify restrictions, you use passwords which can protectboth global and circuit restrictions. It is important that you set passwords immediately whenusing restrictions that you want to keep secure against any modification by students. Thepassword for global restrictions is encrypted and stored in the Multisim program file. Thepassword for circuit restrictions (for restricting only a particular circuit) is encrypted andstored in the circuit file.1.3.1Setting Global RestrictionsUse global restrictions to set the basic level of functionality of Multisim available to studentsin all circuits with which they will work. You can select a default path where circuits are to besaved, hide databases and the In Use List, and determine whether students may editcomponents or place instruments.You can also hide complicated instruments and analysis options from the menus by using thesimplified version. See “1.3.1.2 Simplified Version” on page 1-6.Note Global restrictions are overridden by circuit restrictions if the circuit restrictions aresaved with the circuit. See “1.3.2 Setting Circuit Restrictions” on page 1-9 forinformation.1-4Electronics Workbench

Using Restrictions1.3.1.1 General Global Restrictions To set general global restrictions:1. Choose Options/Global restrictions. The Password dialog box appears.Note The above dialog also appears if you select Options/Circuit restrictions, if you havepreviously set a password by clicking Password from the Circuit restrictions dialogbox. For details on the Circuit restrictions dialog box, see “1.3.2 Setting CircuitRestrictions” on page 1-9.2. Enter the default password “Rodney” (this is case sensitive) and click OK.The Global Restrictions dialog box appears.Note You can, and should, change the default password. (See “1.3.3 Setting Passwords forRestrictions” on page 1-12 for more information).3. If it is not displayed, click the General tab:Enable thesecheckboxes todisallowcomponentediting, to hideparts bins,databases, andthe In Use List.Click here to select adefault path/location tostore circuits.Optionally, click to erasecircuit path.See “1.3.1.2Simplified Version”on page 1-6.Multisim 8 for Educators1-5
