Using the Requirements Management Interface (Requirements Management Interface)

Requirements Management Interface

Opening an Object in the Navigator

Use the Navigator to open the object that needs requirements added or edited. This procedure should be followed after the Navigator is started.

You can use the current model or the file for another object. The object's file must be on the MATLAB path or in the current directory.

To associate requirements with a Simulink or Stateflow object that is already open and is the currently active model,

Select Open Current Model from the File menu in the Navigator

Note The top level system of the Simulink or Stateflow model must be active. For example, if the Simulink f14 model is open with the controller subsystem active, then Open Current Model will not work in the Navigator.

To associate requirements with a Simulink or Stateflow object that is not currently open, or if you want to associate requirements with a MATLAB M-file:

Select Open from the File menu in the Navigator.

The Open Model/File dialog box appears.

Select the object that you want to associate with requirements and click Open.

The object opens in Simulink or Stateflow.

Note While using the Navigator, do not close the model in Simulink.

For a Simulink or Stateflow object, the subsystems, blocks, charts, states, and transitions appear as nodes in a hierarchical tree structure in the left pane of the Navigator. An M-file appears as a single node in the left pane of the Navigator. The following examples show the Navigator's views of Simulink, Stateflow, and M-file objects.

Simulink Chart in the Navigator

This example shows the Simulink engine model in the Navigator.

Stateflow Chart in the Navigator

This example shows a partial view of the fuelsys model, which contains the control logic Stateflow chart in the fuel rate controller subsystem.

Note You must have Stateflow installed in order to expand the Stateflow chart node in the Navigator.

MATLAB M-File in Navigator

This example shows a MATLAB M-file, engine.m, in the Navigator.
