This PSpice demonstration shows use of the Modeling Application. After you complete this PSpice demonstration, you will be able to:
- Create and edit a Piecewise Linear Source (PWL)
- Create, edit, and place a non-ideal component
- Create and edit a system module
To begin, go to the main PSpice menu and select Place > PSpice Component… > Modeling Application.
Or, you can alternatively open the Modeling Application by clicking the Modeling Application icon that is located in the PSpice toolbar.
This opens the Modeling Application in a window located on the right side of your screen.
The Modeling Application window has several menu items. In this video demonstration we will access Sources and System Modules.
First, we will create a Piecewise Linear (PWL) source.
This can easily be accomplished using the Model Editor to configure the time and voltage pairs. You can see from our simulation the changes in voltage at our specified times.
If you want to edit a part created with the Modeling Application, click your right mouse button and select More > Edit PSpice Component or More > Edit Source Component, depending on what you created.
You can then edit you PWL to specify a repeat sequence value.
When we click the Update button our source updates with the new parameters.
Next we will create a non-ideal capacitor. The capacitor found in the Place PSpice Component menu is one that is already completely charged. The Modeling Application includes fields where you can set tolerances and initial conditions as well as parasitic properties and temperature and voltage coefficients.
PSpice also has a Modeling Application > System Modules option. These include switches controlled by time voltage or current, single phase transformers, and voltage-controlled oscillators.
The Modeling Application within PSpice allows you to quickly create models with your preferred parameters, attributes and tolerances and easily place them in your schematic.
