Local components are custom parts that you can use in schematics. They are a combination of a netlist subcircuit and a symbol.

About this task

To create local component, its subcircuit must be described in the netlist of a library that is contained in the project. A symbol is also required, which can be created before or during the creation of the local component.

The content and structure of InfineonSpice libraries follows standard SPICE conventions, as described in Working with libraries. The description of these conventions is beyond the scope of this manual. However, you can find detailed information about it in Infineon’s Titan reference manual and other generally available sources.

Before you begin

The component’s description must be available as a subcircuit in a library in the project. You can make it available by adding it to the library manually or by importing a library containing the description. For more information, see Working with libraries.

If you do not want to create the symbol during the process (as described below), the symbol must be contained in the library. For information on creating symbols, see Working with symbols.

Procedure

  1. In the Workspace view, select the desired project and click the button.
    You can also choose File > New Local Component or right-click the project and choose New Local Component from the context menu.
    The New Device dialog opens.
  2. Enter the name that you want to give the local component and click OK.
    The Properties of Component dialog opens, showing the Basic section.
  3. From the Library list, choose the library that contains the model that you want to use for the component.
  4. From the Model list, choose the model.
  5. Specify the symbol for the custom component.

    • If the symbol already exists in the project, choose it from the Symbol list. Note that you can choose only symbols with the same number of pins as the chosen model.

      Skip to step 10.

    • If the symbol does not already exist, continue with the next step.
  6. Click the + beside the Symbol list.
    The New Symbol dialog opens.
  7. Enter a name for the new symbol and click OK.

    The Symbol Generation Options dialog opens.



    All pin names defined by the model are listed in the Left Pins field, meaning that those pins will be positioned at the left edge of the generated symbol.

  8. If you want to position pins at other edges of the symbol, remove their names from Left Pins and enter them into the desired fields.
  9. Click OK.
    The new symbol is created in the project and opened in a symbol editing tab in the background.
  10. Click OK in the Properties of Component dialog to close the dialog.
    The new custom component is created in the project.
  11. If you have created the symbol during this procedure (and not used a predefined symbol), you can edit it now as desired in the tab that has automatically opened.
    For information on editing symbols, see Working with symbols.

Results

The new custom component is available in the project folder and can be used in schematics.

Note that you cannot edit the local component itself, but you can edit its symbol and its model separately using, respectively, the Open in Symbol Editor and Open in Text Editor context menu commands in the Workspace view.
