Creating Two-Way Links

Two-way links between Simulink objects and DOORS requirements allow you to navigate from the model to the requirements and from the requirements to the model.

Using this feature, the RMI inserts a link object into your requirements module. To create two-way links without modifying your requirements module, see Synchronizing a Simulink Model to a DOORS Surrogate Module.

To create a two-way link between the transmission subsystem in sf_car_doors and the Transmission Requirements requirement:

1. Open the sf_car_doors.mdl model.

2. In the DOORS formal module My Requirements, in the left pane, click the Transmission Requirements node.

   Note   Always select the requirement node by clicking the requirement name in the left pane. Do not use the up and down arrow keys on the keyboard to select a requirement node.

3. In the Model Editor, right-click the transmission subsystem and select Requirements > Add link to current DOORS object.

   The RMI adds the link to the DOORS requirement. The DOORS software inserts a link object below the Transmission Requirements object that represents the link from the requirement to the transmission subsystem in the sf_car_doors model.

   

4. Save the DOORS module.

5. Save the sf_car_doors model.

Navigating Two-Way Links

Once you create a two-way link, you can navigate in both directions between a Simulink object and a DOORS requirement. For information about how to navigate from the Simulink object to a requirement, seeNavigating from a Simulink Object to a DOORS Requirement . The following procedure describes how to navigate from a requirement to its linked Simulink object.

To navigate the two-way link from the Transmission Requirements object in the DOORS database to the transmission subsystem in the sf_car_doors model:

1. In the My Requirements module window, in the left pane, select the [Simulink reference: sf_car_doors/tranmission (SubSystem)] subnode under the Transmission Requirements node.

2. Select MATLAB > Select item.

   The sf_car_doors model highlights the transmission subsystem in the Model Editor.
