Multisim10 simulation software quick start tutorial:

1.1 Digital electronic product schematic design steps
Generally speaking, the design of digital electronic product schematics can be divided into three steps.
1. Determine the input-output relationship based on logical function requirements
2. Select logic devices based on input-output relationships
3. Draw schematic diagram
Use the powerful functions provided by Multisim10 to realize the drawing and simulation of digital electronic product schematics.
1.2 Create circuit diagram
1. Start operation
After starting Multisim10, the following interface appears, as shown in Figure 1-1.

The window that appears after startup is shown in Figure 1-2.

Select File/New/Schematic, and the main design window shown in Figure 1-3 will pop up.

2. Add component
Open the component library toolbar, click the required component icon button as shown in Figure 1-4, then click the left mouse button again at an appropriate position in the main design circuit window, and the required component will appear at that position. As shown in Figure 1-5.

Double-click this component, and the component's dialog box will appear, as shown in Figure 1-6. You can set the component's label, number, value, and model parameters.
3. movement of components,
Select the component and directly drag the component to be moved with the mouse;
4. Copy, delete and rotate components
Select the component, use the corresponding menu, toolbar, or right-click the mouse to pop up the shortcut menu to perform the required operations.
5. Place power and ground components
Select "Place Signal Source Button" to pop up the dialog box shown in Figure 1-7, where you can select power and ground components.
6． Wire handling
(1) Connection. Point the mouse to the end point of a component. When a small dot appears, press the left button of the mouse and drag it to the end point of another component. When the small dot appears, release the left button.
(2) Delete. Select the wire, right-click the mouse, and click "delet" in the pop-up shortcut menu.
1.3 Using instruments
As shown in Figure 1-3, in the main design window, the vertical instrument toolbar on the right side is the instrument toolbar. Commonly used instruments include digital multimeters, function generators, oscilloscopes, Bode plotters, etc., which can be selected and used according to needs.
Example: Selection of multimeter
(1) Call the digital multimeter
Select the digital multimeter from the indicated component library, place it in the main circuit diagram in the same way as selecting other components, double-click the multimeter symbol, and the parameter setting dialog box will pop up, as shown in Figure 1-8.
(2) Multimeter settings
Click "Settings" in the multimeter settings dialog box to pop up the multimeter settings dialog box in Figure 1-9 to set the multimeter parameters and range.
Multimeter parameters and range settings
The use of other instruments is similar to that of a multimeter and will not be described again.
1.4 Real-time simulation
Three-state gate time-sharing transmission circuit. Below the menu bar in the upper left corner is the simulation switch. Click the simulation switch with the left mouse button to start real-time simulation.

1.5 Save files
1. After the circuit diagram is drawn and the simulation is completed, execute "File/Save" in the menu bar to automatically save the file in the original path according to the original file name.
2. Click "File/Save As" in the menu bar in the upper left corner to pop up the dialog box shown in Figure 1-12.
Select the save path in the dialog box and modify the file name to save.
