That process is identical to what we learned earlier, and thus will not be repeated here. Next, you can use the virtual breadboarding result as a visual reference in building the actual circuit in the physical lab. By design we use a simple circuit for illustration. You can of course also place more complex ICs as you would on the actual board.
For breadboarding, there is not much design rule to worry about, and it is mainly a matter of LVS. In making printed circuit boards, there will be some design rules to follow. DRC makes sure that the layout of the part is manufacturable for a given foundry process, e. For instances, if two metal wires are too close together within the same metal layer, they may become shorted unintentionally during the manufacturing process, because of the finite precision that is inherent in the manufacturing.
LVS checking compares the netlist from the schematic with the netlist from virtual breadboard components placement and wiring. In IC design, LVS compares schematic netlist, often from synthesis, with the netlist from physical layout, e.

Multisim is a modeless wiring environment. This means that Multisim determines the functionality of the mouse pointer by the position of the mouse. You do not have to return to the menu to select between the placement, wiring, and editing tools. The last key step is to connect the power supply terminals to the positive and negative power rails of the opamp via a virtual connection using On-page connectors.
You are now ready to run an interactive Multisim simulation; however, you need a way to visualize the data. Multisim provides instruments to visualize the simulated measurements. Instruments can be found on the right menu bar and are indicated by the following icons. In preparation for this we need to take into consideration that sources power, signal and ground are virtual components and, therefore, they cannot be transferred to Ultiboard.
Also, all components must include footprint information. It is a good practice to replace power sources and ground with connectors. Figure Default board outline and parts transferred from Multisim. The Layers tab of the Design Toolbox allows you to move between layers of your design and control the appearance of the layers.
The Select toolbar contains the functions used to control selection filters. In other words, these filters control what can be selected by the mouse pointer. Environment shows products that are verified to work for the solution described in this article. This solution might also apply to other similar products or applications. Software Multisim.
NI Multisim is a powerful schematic capture and simulation environment that engineers, students, and professors can use to simulate electronic circuits and prototype Printed Circuit Boards PCBs. This article shows you how to capture, simulate, and lay out your first design in Multisim. The example circuit in the article is an amplifier circuit. This non-inverting 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.
Introduction For this introductory example, you will simulate a standard non-inverting operational amplifier circuit shown in Figure 1. Figure 1. Non-inverting amplifier circuit. Select Place»Component. Figure 2. Select a Component window. Additional Points The components or parts are organized into Groups and Families to intuitively and logically group common parts together and make searching easier and more effective.
The Component Browser shows the component name, symbol, functional description, model, and footprint all in a single pop-up. Click OK. Move the mouse to the appropriate place on the workspace and left-click once to place the component. After placing the component, the Select a Component window will open again automatically. Additional Points Without a power and ground your simulation cannot run.
By default, the Select a Component window keeps returning as a pop-up until you have completed placing your components. Close the window to return to the schematic entry window.
Now place the remaining circuit components using the techniques discussed in the previous steps. Type AD in the Component field.
Selecting the operational amplifier. Note that this component is a multisection component, as shown by the A and B tabs. Return to the Select a Component window. Select the Basic Group, Resistor Family. Place the resistor.
