Why Use DOORS Requirements with Simulink Objects?

IBM Rational DOORS software is a requirements management application that you use to capture, track, and manage requirements. The Requirements Management Interface (RMI) is a tool set that you use to link objects in a Simulink model to requirements managed by external applications, including the DOORS software.

Simulink models represent functional designs of embedded systems that you build according to specifications and requirements that are managed in DOORS software. Linking Simulink objects to DOORS requirements allows you to:

• Provide traceability from Simulink models to DOORS requirements, which is mandatory for many high-integrity software and hardware projects.

• Access requirements information from each of the linked Simulink objects.

• Use DOORS linking, requirements-analysis, and report-generation capabilities for information captured in both DOORS requirements and Simulink models.

Linking DOORS requirements to Simulink objects allows you to:

• Share design details with engineers who are not directly familiar with the design.

• Improve requirements reviews.

Using RMI and DOORS software, you can:

• Create links between Simulink objects, such as blocks, signals, and subsystems, to DOORS requirements.

• Navigate between Simulink objects and DOORS requirements with links that you created using RMI.

• Create a representation of your Simulink model (called a surrogate module) in the DOORS software. Using the surrogate module, you can create and review requirements without modifying the requirements document and without having to use the Simulink software.

• Create a report for your Simulink model that shows which objects have links to requirements.
