Enhanced Coverage Support for Referenced Models

The previous release introduced coverage support for referenced models, but only by means of functions that you invoke programmatically. This release includes the following enhancements to coverage support for referenced models:

• Redesigned Coverage Settings dialog box now includes controls that allow you to enable coverage for referenced models graphically.

• New Coverage by Model summary that allows you to navigate easily to coverage reports associated with referenced models in a hierarchy.

New Requirements Submenu in Model Explorer

Full access to the Requirements Management Interface is now available from within the Model Explorer. In this release, a Requirements submenu replaces the Edit requirements item that appears in Model Explorer context menus. This new submenu provides several options for adding requirements to model elements and specifying link preferences. This same submenu is available by right-clicking objects in a Simulink model or a Stateflow chart.

Model Advisor Checks for Modeling Standards Enhanced

The Simulink Model Advisor has been enhanced with new and updated verification and validation checks.

• In the Task Hierarchy tree, the check category By Product > Simulink Verification and Validation > Modeling Standards includes the new subcategory IEC 61508 Checks.

• The IEC 61508 Checks subcategory includes new checks that help enforce and document adherence to coding standards for functional safety in electrical, electronic, and programmable electronic systems, as the IEC 61508 standard outlines. For descriptions of the IEC 61508 checks, see Model Advisor Checks in the Simulink Verification and Validation documentation.

• The IEC 61508 checks also appear under the new category By Task > Model-Based Design for IEC 61508.

• Some MathWorks Automotive Advisory Board Checks have been updated.

API for Customizing Model Advisor Enhanced

R2008a provides an enhanced API that allows you to customize the behavior of the Model Advisor for checking and reporting on how well your Simulink models are optimized for simulation and code generation. The API provides classes and functions for defining custom checks and tasks, and writing your own callback functions. For more information, see Customizing the Model Advisor in the Simulink Verification and Validation User's Guide.
