Select Store absolute path to model file.
For this exercise, you save a copy of the example model on the MATLAB path.
If you add requirements to a model that is not on the MATLAB path, you must select
this option to enable linking from your requirements document to your model.
6
In the Apply this user tag to new links field, enter one or more user tags to apply
to the links that you create.
For more information about user tags, see “User Tags and Requirements Filtering”
on page 4-25.

Click Close to close the Requirements Settings dialog box. Keep the
sldemo_fuelsys model open.
Insert Navigation Objects into DOORS Requirements
When you enable Modify destination for bi-directional linking as described in
“Enable Linking from DOORS Databases to Simulink Objects” on page 7-4, the RMI
can insert a navigation object into both the Simulink object and its associated DOORS
requirement. This tutorial uses the sldemo_fuelsys example model to illustrate
how to do this. For this tutorial, you also need a DOORS formal module that contains
requirements.
1
Rename the sldemo_fuelsys model and save it in a writable folder on the
MATLAB path.
2
Start the DOORS software and open a formal module that contains requirements.
3
Select the requirement that you want to link to by left-clicking that requirement in
the DOORS database.
4
In the sldemo_fuelsys model, select an object in the model.
This example creates a requirement from the fuel_rate_control subsystem.
5
Right-click the Simulink object (in this case, the fuel_rate_control subsystem)
and select Requirements Traceability > Link to Selection in DOORS.
The RMI creates the link for the fuel_rate_control subsystem. It also inserts a
navigation object into the DOORS formal module—a Simulink reference object ( )
that enables you to navigate from the requirement to the model.
