3. Introduction
 Electronic WorkBench (EWB) is a simulation package
for electronic circuits.
 The National Instruments is responsible for
innovating circuit design software EWB.
 Board-level design on PC.
 Design and analyze circuits without using
breadboards, real components or actual instruments.

4. Handling the software
 Double click on its icon.
 An empty circuit window will appear with 2 toolbar.
 Circuit toolbar with the common file management,
editing and graphics tools.
 Parts Bin toolbar from which a wide range of circuit
elements, and instruments can be selected.

5. User interface of Multisim 11.0

6. Circuit Simulation
Building and testing a circuit
A resistive voltage divider circuit

7. Steps for circuit Building
 Place components on circuit window.
 Arrange circuit elements.
 Wire the components together.
 Set values for components.
 Save the circuit.

8. Circuit testing
 Attach voltmeter.
 Make changes and additions
 Add an ammeter to the circuit to measure the current
through the resistor.
 Change the value of the resistor and observe the
change in current and voltage.

9. Bridge Rectifier

10. Salient Features
 It has a large number of virtual instrument.
 Advantage of the full power of simulation without
having to be an expert.
 These instruments are wired into the schematic just
like we connect a real instrument on the bench.
 Virtual instrument : Ammeter, Voltmeter, Distortion
Analyzer, Frequency Counter, Function
Generator, Multimeter, and many more.

11. Overview of application
With its many desirable features…….
 EWB play an important role in teaching.
 Understanding of basic circuits and electronics.
 Desirable in the pre-lab stage pro-type development.
 In the pre-lab assignments/exercises.
 Design projects.
 Electronic industries where before implementation
circuit simulation is required.

12. Conclusion
 Build and test circuits entirely on the Workspace using
the mouse and menus.
 International market leader.
 World’s most widely used circuit design software.
 Most successful simulator in the industry.
 Over 180,000 users worldwide.
 Delivers real laboratory Environment.
 Student version of the EWB can handle up to 30 active
devices with no limits on the number of passive
derives.
