systemcomposer.updateLinksToReferenceRequirements

Update requirement links to model reference requirements

Syntax

systemcomposer.updateLinksToReferenceRequirements(modelName,linkDomain,documentPathOrID)

Description

systemcomposer.updateLinksToReferenceRequirements(modelName,linkDomain,documentPathOrID) imports the external requirement document into Simulink^® Requirements™ as a reference requirement and updates the requirement links to point to the imported set. You can use the systemcomposer.updateLinksToReferenceRequirements function in System Composer™ to make the requirement links point to imported referenced requirements instead of external documents.

Examples

Update Reference Requirement Links from Imported File

After importing requirement links from a file, update links to reference requirements for the model to make full use of the Simulink® Requirements™ functionality.

model = systemcomposer.openModel('reqImportExample');

Note: Importing or linking requirements may not work with a web-based Microsoft® Office file stored in SharePoint or OneDrive. Use a local copy of the file.

Import Requirement Links from Word File

Open the Microsoft® Word file Functional_Requirements.docx with the requirements listed. Highlight the requirement to link.

In the model, select the component to which to link the requirement. Right-click the component and select Requirements > Link to Selection in Word.

Export Model and Save to External File

Export the model and save to an external file.

exportedSet = systemcomposer.exportModel('reqImportExample');
SaveToExcel('exportedModel',exportedSet);

Import Requirement Links from File and Import to Model

Use the external file to import requirement links into another model.

structModel = ImportModelFromExcel('exportedModel.xls','Components','Ports', ...
'Connections','PortInterfaces','RequirementLinks');
structModel.readTableFromExcel

systemcomposer.importModel('reqNewExample',structModel.Components, ...
structModel.Ports,structModel.Connections,structModel.Interfaces,structModel.RequirementLinks);

Update Links to Reference Requirements

To integrate the requirement links to the model, update references within the model.

systemcomposer.updateLinksToReferenceRequirements("reqNewExample","linktype_rmi_word","Functional_Requirements.docx")

Open the Requirements perspective from the bottom right corner of the model palette to view the requirements.

Definitions

Term	Definition	Application	More Information
requirements	Requirements are a collection of statements describing the desired behavior and characteristics of a system. Requirements ensure system design integrity and are achievable, verifiable, unambiguous, and consistent with each other. Each level of design should have appropriate requirements.	To enhance traceability of requirements, link system, functional, customer, performance, or design requirements to components and ports. Link requirements to each other to represent derived or allocated requirements. Manage requirements from the Requirements Manager on an architecture model or through custom views. Assign test cases to requirements using the Test Manager for verification and validation.	Link and Trace Requirements
requirement set	A requirement set is a collection of requirements. You can structure the requirements hierarchically and link them to components or ports.	Use the Requirements Editor to edit and refine requirements in a requirement set. Requirement sets are stored in .slreqx files. You can create a new requirement set and author requirements using Simulink Requirements, or import requirements from supported third-party tools.	Manage Requirements
requirement link	A link is an object that relates two model-based design elements. A requirement link is a link where the destination is a requirement. You can link requirements to components or ports.	View links using the Requirements perspective in System Composer. Select a requirement in the Requirements Browser to highlight the component or the port to which the requirement is assigned. Links are stored externally as .slmx files.

test harness	A test harness is a model that isolates the component under test, with inputs, outputs, and verification blocks configured for testing scenarios. You can create a test harness for a model component or for a full model. A test harness gives you a separate testing environment for a model or a model component.	Create a test harness for a System Composer component to validate simulation results and verify design. The Interface Editor is accessible in System Composer test harness models to enable behavior testing and implementation-independent interface testing.
