Description

Use the Requirements Editor app to create requirement sets, requirements, import and export requirements, and link requirements to blocks and other supported artifacts.

This image shows the Requirements Editor. The editor contains two requirement sets.

Open the Requirements Editor App

  • Simulink® Toolstrip: On the Apps tab, under Model Verification, Validation, and Test, click Requirements Editor.

  • MATLAB® Toolstrip: On the Apps tab, under Verification, Validation, and Test, click Requirements Editor.

  • MATLAB command prompt: Enter slreq.editor.

Examples

To create a new requirement set:

  1. In the Requirements Editor, click New Requirement Set.

  2. Specify the name and file location of the requirement set. The editor saves the requirement set as a SLREQX file and the requirement set appears in the Requirements Editor.

You can open existing requirement sets by clicking Open and selecting a requirement set file. To delete a requirement set, click a requirement set and click the Close button . Removing a requirement set does not delete the SLREQX file.

To add requirements to a requirement set:

  1. In the left pane, select a requirement set.

  2. In the Requirements section, click Add Requirement.

Each requirement you create creates an associated slreq.Requirement object. You can edit the properties of the requirement in the Requirements Editor or programmatically. To adjust the properties in the Requirements Editor, click the requirement. The properties appear in the right pane of the editor.

To link requirements to artifacts in models:

  1. In an open Simulink model, click a model artifact. For a list of supported model artifacts, see Supported Model Objects for Requirements Linking.

  2. In the Requirements Editor, click the requirement you want to link.

  3. In the Links section, click Add Link > Link from Selection in Simulink.

For more information, see Create and Store Links.

To link requirements to lines of MATLAB code or to plain text code, such as C or H files:

  1. Open the MATLAB code or plain text code in the MATLAB Editor.

    Note

    You cannot create links to MATLAB code in MLX files.

  2. Select the lines of code that you want to link.

    Tip

    To link to MATLAB functions and enable change tracking for the entire body of the function, create the link to the line that contains the function keyword.

  3. In the Requirements Editor, select the requirement you want to link.

  4. In the Links section, click Add Link > Link from Selection in MATLAB Editor.

For more information, see Create and Store Links.

To set the value of built-in requirement properties, custom attributes, or stereotype properties:

  1. Open a requirement set.

  2. In the View section, click Show Requirements.

  3. Select a requirement.

  4. Set the value of a property or attribute in the right pane:

    • Built-in property — Under Properties, set the property to the specified value.

    • Custom attribute — Under Custom Attributes, set the custom attribute to the specified value.

    • Stereotype property — Under Stereotype Attributes, set the stereotype property to the specified value.

To set the value of built-in link properties, custom attributes, or stereotype properties:

  1. Open a requirement set.

  2. In the View section, click Show Links.

  3. Select a link.

  4. Set the value of a property or attribute in the right pane:

    • Built-in property — Under Properties, set the property to the specified value.

    • Custom attribute — Under Custom Attributes, set the custom attribute to the specified value.

    • Stereotype property — Under Stereotype Attributes, set the stereotype property to the specified value.

By default, the Requirements Editor displays loaded requirements in alphabetical order. To reduce the number of requirements displayed, search displayed requirements.

  1. Open a requirement set.

  2. In the View section, click Show Requirements.

  3. In the Edit section, click Search.

When you perform a search:

  • A requirement set is not visible if none of the requirements in the set pass the filter. If a child requirement passes the filter, the parent requirement set is also visible.

  • The filter is not case-sensitive. For example, typing A displays the requirements whose columns contain an uppercase or lowercase A.

  • The filter applies to the columns in the editor. If you add columns, the filter automatically applies to them.

By default, the Requirements Editor displays links to loaded requirement sets, in alphabetical order. To reduce the number of links displayed, search displayed links.

  1. Open a requirement set.

  2. In the View section, click Show Links.

  3. In the Edit section, click Search.

To display additional columns in the left pane:

  1. Decide if you want to view requirement or link sets. To view requirement sets, in the View section, click Show Requirements. To view link sets, in the View section, click Show Links.

  2. In the View section, click the Columns button .

If you selected Show Requirements, you can select from these options:

  • Implementation Status: Displays the implementation status summaries for your requirement sets. For more information, see Review Requirements Implementation Status.

  • Verification Status: Displays the verification status summaries for your requirement sets. For more information, see Review Requirements Verification Status.

  • Select Attributes: Select additional attributes to display. You can display the Index, ID, Summary,Type, Keywords, SID, CreatedOn, CreatedBy, ModifiedOn, SyncronizedOn, ModifiedBy, Revision, Verified, Implemented, Description, Rationale. The default attributes are Index, ID, and Summary.

If you selected Show Links, you can only click Select Attributes. You can then select the following attributes: Label, Source, Type,Destination, Keywords, SID, CreatedOn, CreatedBy, ModifiedOn, ModifiedBy, Revision, Description, and Rationale. The default attributes are Label, Source, Type, and Destination.

Once you display the attributes, you can filter them with the Search feature.

To import requirements from a third-party requirements application:

  1. In the File section, click Import to open the Import Requirements window.

  2. In the Document Type property, select the file format. You can select Microsoft® Word, Microsoft Excel®, ReqIF™ File, and IBM® DOORS® Next.

  3. In the Document Location property, select the location of the file.

  4. Set the import options. Each format has different import options.

If you import the requirements, Requirements Toolbox™ creates an slreq.Requirement object for each requirement. If you import the requirements as referenced requirements, Requirements Toolbox creates an slreq.Reference object for each requirement. For more information, see Import Requirements from Third-Party Applications.

To create a report for one or more requirement sets:

  1. In the Share section, click Export > Generate Report. The Report Generation Options window opens.

  2. Set the file name and location of the report by clicking the Select button.

  3. Select the report content options.

  4. Select the requirement sets to include in the report. The Included Requirement Sets section displays the loaded requirement sets. To add a requirement set, open the requirement set using the Requirements Editor.

  5. Click Generate Report.

For more information, see Report Requirements Information.

To access the Traceability Matrix window:

In the Analyze section, click Traceability Matrix. You can then create a traceability matrix in the window. For more information, see Track Requirement Links with a Traceability Matrix.

To create a traceability diagram:

  1. Click a requirement set.

  2. In the Analyze section, click Traceability Diagram.

For more information, see Visualize Links with a Traceability Diagram.

If you have a license for Simulink Check™, you can also open the model testing dashboard. To open the model testing dashboard:

In the Analyze section, click Model Testing Dashboard. For more information, see Assess Requirements-Based Testing Quality by Using the Model Testing Dashboard (Simulink Check) and Explore Status and Quality of Testing Activities Using Model Testing Dashboard (Simulink Check).
