Configure AUTOSAR Adaptive Elements and Properties

In Simulink^®, you can use the AUTOSAR Dictionary and the Code Mappings editor separately or together to graphically configure an AUTOSAR adaptive software component and map Simulink model elements to AUTOSAR component elements. For more information, see AUTOSAR Component Configuration.

Use the AUTOSAR Dictionary to configure AUTOSAR elements from an AUTOSAR perspective. Using a tree format, the AUTOSAR Dictionary displays a mapped AUTOSAR adaptive component and its elements, communication interfaces, and XML options. Use the tree to select AUTOSAR elements and configure their properties. The properties that you modify are reflected in exported ARXML descriptions and potentially in generated AUTOSAR-compliant C++ code.

AUTOSAR Elements Configuration Workflow

To configure AUTOSAR component elements for the Adaptive Platform in Simulink:

Open a model for which the AUTOSAR system target file autosar_adaptive.tlc is selected.
Create or open a mapped view of the AUTOSAR model. In the model window, do one of the following:
- From the Apps tab, open the AUTOSAR Component Designer app.
- Click the perspective control in the lower-right corner and select Code.
If the model has not yet been mapped to an AUTOSAR software component, the AUTOSAR Component Quick Start opens. Work through the quick-start procedure and click Finish. For more information, see Create Mapped AUTOSAR Component with Quick Start.
The model opens in the AUTOSAR Code perspective. This perspective displays the model and directly below the model, the Code Mappings editor.
Open the AUTOSAR Dictionary. Either click the AUTOSAR Dictionary button in the Code Mappings editor or, on the AUTOSAR tab, select Code Interface > AUTOSAR Dictionary.
To configure AUTOSAR elements and properties, navigate the AUTOSAR Dictionary tree. You can add elements, remove elements, or select elements to view and modify their properties. Use the Filter Contents field (where available) to selectively display some elements, while omitting others, in the current view.
After configuring AUTOSAR adaptive elements and properties, open the Code Mappings editor. Use Code Mapping tabs to map Simulink elements to new or modified AUTOSAR elements.
To validate the AUTOSAR component configuration, click the Validate button . If errors are reported, address them, and then retry validation.

Imported AUTOSAR XML files retain their file structure, as described in Round-Trip Preservation of AUTOSAR XML File Structure and Element Information. Select one of the following values for Exported XML file packaging.

Single file — Exports XML into a single file, modelname.arxml.

Modular — Exports XML into multiple files, named according to the type of information contained.

Exported File Name File Contents

Exported File Name	File Contents
`modelname_component.arxml`	Adaptive software components, including required and provided ports. This file is the main ARXML file exported for the Simulink model. In addition to software components, the component file contains packageable elements that the exporter does not move to data type or interface files based on AUTOSAR element category.
`modelname_datatype.arxml`	Data types and related elements, including: Application data types Standard Cpp implementation data types Constant specifications Physical data constraints Units and unit groups Software record layouts
`modelname_interface.arxml`	Adaptive interfaces, including required and provided service interfaces with namespaces and events.

modelname_component.arxml

Adaptive software components, including required and provided ports.

This file is the main ARXML file exported for the Simulink model. In addition to software components, the component file contains packageable elements that the exporter does not move to data type or interface files based on AUTOSAR element category.

modelname_datatype.arxml

Data types and related elements, including:

Application data types
Standard Cpp implementation data types
Constant specifications
Physical data constraints
Units and unit groups
Software record layouts

modelname_interface.arxml Adaptive interfaces, including required and provided service interfaces with namespaces and events.

Alternatively, you can programmatically configure exported XML file packaging by calling the AUTOSAR set function. For property ArxmlFilePackaging, specify either SingleFile or Modular. For example:

arProps = autosar.api.getAUTOSARProperties(hModel);
set(arProps,'XmlOptions','ArxmlFilePackaging','SingleFile');

For the Adaptive Platform, model builds also generate XML manifests for AUTOSAR executables and service instances. For more information, see Generate AUTOSAR Adaptive C++ and XML Files.

AUTOSAR Package Paths

In the XML options view, you can configure AUTOSAR packages (AR-PACKAGEs), which contain groups of AUTOSAR elements and reside in a hierarchical AR-PACKAGE structure. The AR-PACKAGE structure for a component is logically distinct from the ARXML file partitioning selected with the XML option Exported XML file packaging or imported from AUTOSAR XML files. For more information about AUTOSAR packages, see Configure AUTOSAR Packages.

Inspect and modify the AUTOSAR package paths grouped under the headings Package Paths and Additional Packages.

Alternatively, you can programmatically configure an AUTOSAR package path by calling the AUTOSAR set function. Specify a package property name and a package path. For example:

arProps = autosar.api.getAUTOSARProperties(hModel);
set(arProps,'XmlOptions','ApplicationDataTypePackage',...
    '/Company/Powertrain/DataTypes/ApplDataTypes');

For more information about AUTOSAR package property names and defaults, see Configure AUTOSAR Packages and Paths.

Additional XML Options

In the XML options view, under the heading Additional Options, you can configure aspects of exported AUTOSAR XML content.

You can:

Optionally override the default behavior for generating AUTOSAR application data types in ARXML code. To force generation of an application data type for each AUTOSAR data type, change the value of ImplementationDataType Reference from Allowed to NotAllowed. For more information, see Control Application Data Type Generation.
Control the default value of the SwCalibrationAccess property of generated AUTOSAR measurement variables, calibration parameters, and signal and parameter data objects. For SwCalibrationAccess DefaultValue, select one of the following values:
- ReadOnly — Read access only.
- ReadWrite (default) — Read and write access.
- NotAccessible — Not accessible with calibration and measurement tools.
For more information, see Configure SwCalibrationAccess.
Optionally override the default behavior for generating internal data constraint information for AUTOSAR implementation data types in ARXML code. To force export of internal data constraints for implementation data types, select the option Internal DataConstraints Export. For more information, see Configure AUTOSAR Internal Data Constraints Export.
Specify the form in which to generate adaptive service instance information. Set Identify Service Instance Using to InstanceIdentifier or InstanceSpecifier. The form that you select is used to identify service instances in generated Proxy and Skeleton functions. For more information, see Configure AUTOSAR Adaptive Service Instance Identification.
Specify the network binding option through which the AUTOSAR adaptive applications communicate with each other. Set the option to DDS or SOME/IP.

Alternatively, you can programmatically configure the additional XML options by calling the AUTOSAR set function. Specify a property name and value. The valid property names are ImplementationTypeReference, SwCalibrationAccessDefault, InternalDataConstraintExport, IdentifyServiceInstance, and NetworkBinding. For example:

arProps = autosar.api.getAUTOSARProperties(hModel);
set(arProps,'XmlOptions','ImplementationTypeReference','NotAllowed');
set(arProps,'XmlOptions','SwCalibrationAccessDefault','ReadOnly');
set(arProps,'XmlOptions','InternalDataConstraintExport',true);
set(arProps,'XmlOptions','IdentifyServiceInstance','InstanceSpecifier')
set(arProps,'XmlOptions','NetworkBinding','SOME/IP')
