Delete Requirements Links from Simulink Objects

Delete a Single Link from a Simulink Object

If you have an obsolete link to a requirement, delete it from the model object.

To delete a single link to a requirement from a Simulink® model object:

  1. Right-click a model object and select Requirements Traceability > Open Link Editor.

  2. In the top-most pane of the Link Editor, select the link that you want to delete.

  3. Click Delete.

  4. Click Apply or OK to complete the deletion.

Delete All Links from a Simulink Object

To delete all links to requirements from a Simulink model object:

  1. Right-click the model object and select Requirements Traceability > Delete All Links

  2. Click OK to confirm the deletion.

    This action deletes all requirements at the top level of the object. For example, if you delete requirements for a subsystem, this action does not delete any requirements for objects inside the subsystem; it only deletes requirements for the subsystem itself. To delete requirements for child objects inside a subsystem, Model block, or Stateflow® chart, you must navigate to each child object and perform these steps for each object from which you want to delete requirements.

Delete All Links from Multiple Simulink Objects

To delete all requirements links from a group of Simulink model objects in the same model diagram or Stateflow chart:

  1. Select the model objects whose requirements links you want to delete.

  2. Right-click one of the objects and select Requirements Traceability > Delete All.

  3. Click OK to confirm the deletion.

    This action deletes all requirements at the top level of each object. It does not delete requirements for child objects inside subsystems, Model blocks, or Stateflow charts.
