System Requirements

List system requirements in Simulink models

Library

Simulink® Verification and Validation

Description

The System Requirements block lists the system-level requirements associated with a model or subsystem. This block is dynamically populated. It displays system requirements associated with the level of hierarchy in which the block appears in the model. It does not list requirements associated with individual blocks in the model. To ensure that all requirement links are listed in the System Requirements block:

  1. Right-click the background of your model.

  2. Select Requirements Traceability at This Level.

  3. From the top of the context menu, verify that all the requirements you want to list appear in the System Requirements block.

You can place this block anywhere in your model. It does not connect to other Simulink blocks. You can have only one System Requirements block in a given subsystem.

When you insert this block into your Simulink model, it is populated with the system requirements, as shown in the Airflow Calculation subsystem of the slvnvdemo_fuelsys_officereq example.

Each of the listed requirements is an active link to the requirements document. When you double-click a requirement label, the associated requirements document opens in its editor window, scrolled to the target location.

Parameters

Block Title

The title of the system requirements list in the model. The default title is System Requirements. You can enter a customized title, for example, Engine Requirements.
