This article shows you how to capture and simulate a simple circuit in Multisim.This tutorial takes less than 30 minutes to complete and consists of 50 short steps.The example circuit in the article is an amplifier circuit. This noninverting operational amplifier configuration consists of one active component (the operational amplifier) and two passive resistor components that will be used to complete the feedback network to provide gain in this circuit.Table of Contents1. Example Circuit2. Step 1: Open Multisim3. Step 2: Place Components4. Step 3: Wire Components5. Step 4: Place a Simulation Source6. Step 5: Place Measurement Instruments7. Step 6: Run a SimulationExample CircuitFor this introductory example, simulate a standard noninverting operational amplifier circuit (pictured in Figure 1). The gain of this noninverting amplifier is calculated simply with Gain = 1 + R1/R2.Therefore if R1 = R2 then the gain is equal to 2, which you can verify when you run an interactive simulation in NI Multisim software.Figure 1. Example CircuitStep 1: Open MultisimBegin by drawing your schematic in the Multisim environment.1. Select Start»All Programs»National Instruments»Circuit Design Suite 11.0»Multisim 11.0 to open Multisim.2. Multisim opens showcasing the default capture and simulation environment.
Figure 2. Multisim EnvironmentThere are two fundamental tasks in the design of a circuit: the placement of components and the wiring of these components to create a complete design.1. To select a component, go to Place»Component …2. The Select a Component dialog appears (also known as the Component Browser).Figure 3. Select a Component DialogThe component browser organizes the database components into three logical levels. The Master Database contains all shipping components in a read-only format. The Corporate Database is where to save custom components to be shared with colleagues (via a network collection and so on). Finally, the User Database is where custom components are saved that can be used only by the specific designer.
