Synchronize a Simulink Model to Create a Surrogate Module

Synchronize a Simulink Model to Create a Surrogate Module
The first time that you synchronize your model with the DOORS software, the DOORS
software creates a surrogate module.
In this tutorial, you synchronize the sf_car model with the DOORS software.
Note: Before you begin, make sure you know how to create links from a Simulink model
object to a requirement in a DOORS database. For a tutorial on creating links to DOORS
requirements, see “Link to Requirements in IBM Rational DOORS Databases” on page
2-32.
1
To create a surrogate module, start the DOORS software and open a project. If the
DOORS software is not already running, start the DOORS software and open a
project.
2
Open the sf_car model.
3
Rename the model to sf_car_doors, and save the model in a writable folder.
4
Create links to a DOORS formal module from two objects in sf_car_doors:
• The transmission subsystem
• The engine torque block inside the Engine subsystem
5
Save the changes to the model.
6
In the Simulink Editor, select Analysis > Requirements Traceability >
Synchronize with DOORS.
The DOORS synchronization settings dialog box opens.
7
For this tutorial, accept the default synchronization options.
The default option under Extra mapping additionally to objects with links,
None, creates objects in the surrogate module only for the model and any model
objects with links to DOORS requirements.
Note: For more information about the synchronization options, see “Customize
DOORS Synchronization” on page 6-8.
8
Click Synchronize to create and open a surrogate module for all DOORS
requirements that have links to objects in the sf_car_doors model.
