Get Started with Requirements Toolbox

Author, link, and validate requirements for designs and tests

Requirements Toolbox™ lets you author, link, and validate requirements within MATLAB® or Simulink®. You can create requirements using rich text with custom attributes or import them from requirements management tools.

You can link requirements to MATLAB code, System Composer™ or Simulink models, and tests. The toolbox analyzes the traceability to identify gaps in implementation or testing. The design highlighting and traceability matrix summarize where links exist across multiple artifacts and guide you to address any gaps. When requirements change, linked artifacts are highlighted, and you can determine the upstream and downstream artifacts affected using a traceability diagram. Generated code from Simulink designs includes code comments that document where requirements are implemented to assist with reviews.

You can formalize requirements and analyze them for consistency, completeness, and correctness using the Requirements Table. The Requirements Perspective enables you to view and manage requirements together with design. When used with Simulink, you can create links to blocks with a simple drag and drop.

Support for industry standards is available through IEC Certification Kit (for ISO 26262 and IEC 61508) and DO Qualification Kit (for DO-178).

Import and Edit Requirements from a Microsoft Word Document

Import and update requirements from a Microsoft® Word requirements document. After you import the requirements, you can modify the requirements in either the Requirements Editor or the Word document. This functionality is available only on Microsoft Windows® platforms. Simulink® Online™ does not support importing requirements from Microsoft Word documents.
