AUTOSAR Blockset Checks

R2026b

MathWorks Automotive Advisory Board Checks

Use AUTOSAR Blockset Model Advisor and Upgrade Advisor checks to configure your model for AUTOSAR standard compatibility.

Check model configuration parameters for AUTOSAR compliance

Check ID: mathworks.autosar.autosar_configset

Description

Check configuration settings in the model configuration that apply to AUTOSAR compatibility.

Available with AUTOSAR Blockset.

Results and Recommended Actions

ConditionRecommended Action
One or more of the model configuration parameters are not compatible with AUTOSAR.Set the listed configuration parameters to the recommended values. Alternatively, you can automatically set the parameters by using the Auto-Fix option.

This table lists the model parameters the check examines and the values that the parameters are set to if an automatic fix is applied by the Model Check Advisor. The model examined by Model Check Advisor must have configuration parameter System target file (Simulink Coder) set to autosar.tlc or autosar_adaptive.tlc.

Upgrade AUTOSAR Adaptive model to current modeling style

Check ID: mathworks.autosar.modelingStyleCheck

Description

Checks that the model is configured for the AUTOSAR Adaptive Platform and implements compatible modeling styles.

Available with AUTOSAR Blockset.

Results and Recommended Actions

ConditionRecommended Action
Model is configured for the AUTOSAR Adaptive Platform and was created in a release before R2026b.Upgrade your model to R2026b by using the Fix button or by using the autosar.api.upgrade function.
Model is already configured for the AUTOSAR Adaptive Platform and is up-to-date.No action required.

Capabilities and Limitations

  • Applies only to models mapped to an AUTOSAR Adaptive software component.

  • Not all models configured for the AUTOSAR Adaptive Platform can be completely upgraded by the software. After the software finishes upgrading a model, review the model for any incomplete transformations. For more information, see Upgrade AUTOSAR Adaptive Models

Replace root ports with bus element ports in AUTOSAR Classic model

Check ID: mathworks.autosar.convertible_ports_check

Description

Identify root-level ports that are mapped to AUTOSAR port elements, and automatically replace them with bus element ports in models configured for the AUTOSAR Classic Platform.

Available with AUTOSAR Blockset.

Results and Recommended Actions

ConditionRecommended Action
Model contains root-level Inport or Outport blocks that can be replaced with bus element ports.Replace root-level Inport or Outport blocks with In Bus Element and Out Bus Element blocks by using the Fix button or by using the autosar.api.upgrade function.
Model is already using root-level bus element ports with valid AUTOSAR mappings.No action required.
Model has an invalid AUTOSAR mapping.Fix the invalid mappings before running this check.

Capabilities and Limitations

  • Applies only to models mapped to an AUTOSAR Classic software component.

  • Does not apply to AUTOSAR architecture models or models mapped to an AUTOSAR Adaptive software component.
