Connecting Interfaces

You can create a connection between two functional or logical interfaces. The connection appears in the 2D graph and materializes the exchange of data between two functions or logical components.

Moreover, interfaces enable you to connect subflows or subtypes without using a MUX/DEMUX.

Note that you can connect functional or logical interfaces only if they have identical flow or type and compatible directions.

This task shows you how to:

Before you begin: In Me > Preferences > App Preferences > 3D Modeling Systems Architecture > Functional & Logical Design > General, select the Create Interfaces option in the Connection Creation Default Mode area. For more information, see Native Apps Preferences Guide: General.

Connect within the 2D Graph

You can create a connection within the 2D graph. The scenario is identical for functional and logical interfaces.

  1. Select a functional or logical interface.
  2. From the Edition section of the action bar, click Create New Functional/Logical Connection .

    Tip: The command is also available from the context menu.

    A connection line appears under your pointer.
  3. Click a function or a logical component or an interface.
    The Functional/Logical Connection dialog box appears.
  4. In the Functional/Logical Connection tab:
    1. In the Title box, enter the title to be displayed in the tree and in the 2D representation.

      Note: The Name box displays the non-editable and unique key server identifier.

    2. Optional: Enter a description.
  5. Click OK to validate.
    The connection is created. It appears in the 2D graph and in the Connections folder in the tree.
    Note: If you connect an interface to a function or a logical component, a second interface is automatically created with the same flow or type as the first interface.

Connect within the Interface Decomposition Panel

You can create connections between interfaces by using the Interface Decomposition Panel. The scenario is identical for functional and logical interfaces.

  1. Right-click the interfaces you want to connect and in the context menu, click Interface Decomposition Panel.
    The Interface Decomposition panel appears.
  2. In the Structure column of the first Interface Decomposition panel, select a flow or type exposition.

    Note: You can also select a subflow or a subtype and drop it under a subflow or subtype.

  3. Drag your selection and drop it under a flow or type in the Structure column of the second Interface Decomposition panel.
  4. In the Functional/Logical Connection tab:
    1. In the Title box, enter the title to be displayed in the tree and in the 2D representation.

      Note: The Name box displays the non-editable and unique key server identifier.

    2. Optional: Enter a description.
  5. Click OK to validate.
    • The connection is created. It appears in the 2D graph and in the Connections folder in the tree.
    • The Interface Decomposition panel displays the connection in the Connected to column.
