Generating a Function Chain

Under a function reference, you can generate a function chain. When an instance, an output port or an interface is selected, the next leaf instance is placed in a diagram view.

Before you begin: For the purpose of this scenario, create five function instances under a root function reference, and connect them as follows
  • F0 connected to F1
  • F1 connected to F2 and F3
  • F2 connected to F1 and F4
  • F3 connected to F4


  1. In the tree, select the function instance F0.

    You can also select the function instance in the main view.

  2. In the Sheet dialog box, enter a name for the sheet.
  3. In the View dialog box, enter a name for the diagram view.
    A diagram view is created and the function instance F0 is placed.

  4. In the diagram view, select the function instance F0.
    The function instance F1 is placed.

  5. Select the function instance F1.
  6. In the Leaves of Function dialog box, select the ports to be connected.
    F2 and F3 function instances are placed since they are both connected to F1.

  7. Select the function instance F2.
    The F4 function instance is placed.

  8. In the dialog box, click Create New Occurrence and select F1.
    A new occurrence of the function instance F1 is created.

  9. Select the new occurrence of F1, click Select Existing Occurrence and then, select F2.
    A connection between the new occurrence of F1 and F2 is created.
