Link Signal Builder Blocks to Model Objects

This example shows how to create links from a signal group in a Signal Builder block to a model object:

  1. Open the sf_car model.

  2. Open the sf_car/shift_logic chart.

  3. Right-click upshifting and select Requirements Traceability > Select for Linking with Simulink.

  4. In the sf_car model window, double-click the User Inputs block.

    The Signal Builder dialog box opens, displaying four groups of signals. The Passing Maneuver signal group is the current active group. The RMI associates any requirements links that you add to the current active signal group.

  5. In the Signal Builder dialog box, click the Gradual Acceleration tab.

  6. At the far-right end of the toolbar, click the Show verification settings button . (You might need to expand the Signal Builder dialog box for this button to become visible.)

    A Requirements pane opens on the right-hand side of the Signal Builder dialog box.

  7. Place your cursor in the window, right-click, and select Open Link Editor.

    The Requirements Traceability Link Editor opens.

  8. Click New. In the Description field, enter Upshifting.

  9. In the Document type field, select Simulink. Click Use current. The software fills in the field with the Location: (Type/Identifier) information for upshifting.

  10. Click Apply to create the link.

  11. In the model window, select the User Inputs block, right-click, and select Requirements Traceability.

    The link to the new requirement is the option at the top of the submenu.

  12. To verify that the links were created, in the sf_car model window, select Analysis > Requirements Traceability > Highlight Model.

    The blocks with requirements links are highlighted.

      Note:   Links that you create in this way associate requirements information with individual signal groups, not with the entire Signal Builder block.

  13. Close the sf_car model.
