Configure AUTOSAR Elements and Properties

In Simulink^®, you can use the AUTOSAR Dictionary and the Code Mappings editor separately or together to graphically configure an AUTOSAR 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 component and its elements, communication interfaces, computation methods, software address methods, 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 Classic Platform in Simulink:

Open a model for which AUTOSAR system target file autosar.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 a help panel, a Property Inspector dialog box, and, directly under the model, the Code Mappings editor.
Open the AUTOSAR Dictionary. Either click the AUTOSAR Dictionary button in the Code Mappings editor or, in the AUTOSAR tab, select Settings > 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 elements and properties, open the Code Mappings editor. Use the Code Mapping tabs to map Simulink elements to new or modified AUTOSAR elements.
Click the Validate button to validate the AUTOSAR component configuration. If errors are reported, address them and then retry validation.

The XML options view in the AUTOSAR Dictionary displays XML export parameters and their values. You can configure:

XML options source (for components in architecture modeling)
XML file packaging for AUTOSAR elements created in Simulink
AUTOSAR package paths
Aspects of exported AUTOSAR XML content

XML Options Source
Exported XML File Packaging
AUTOSAR Package Paths
Additional XML Options

XML Options Source

The XML options view displays the parameter XML Options Source. If the current component model is contained in an AUTOSAR architecture model, this parameter indicates which XML options to use in model builds. Specify Inherit from AUTOSAR architecture model to use shared architecture model XML option settings, which promote consistency across the model hierarchy. Specify Inlined in this model to override the shared settings with the component model local XML option settings.

If the current component model is not contained in an AUTOSAR architecture model, the XML Options Source parameter has no effect.

Alternatively, you can programmatically configure the XML options source by calling the AUTOSAR set function. For property XmlOptionsSource, specify either Inlined or Inherit. For example:

arProps = autosar.api.getAUTOSARProperties(hModel);
set(arProps,'XmlOptions','XmlOptionsSource','Inlined');

For more information about architecture model XML options, see Generate and Package AUTOSAR Composition XML Descriptions and Component Code.

Exported XML File Packaging

In the XML options view, you can specify the granularity of XML file packaging for AUTOSAR elements created in Simulink. (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	By Default Contains...
`modelname_component.arxml`	Software components, including: Ports Events Runnables Inter-runnable variables (IRVs) Included data type sets Component-scoped parameters and variables This 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, implementation, interface, or timing files based on AUTOSAR element category.
`modelname_datatype.arxml`	Data types and related elements, including: Application data types Software base types Data type mapping sets Constant specifications Physical data constraints System constants Software address methods Mode declaration groups Computation methods Units and unit groups Software record layouts Internal data constraints
`modelname_implementation.arxml`	Software component implementation, including code descriptors.
`modelname_interface.arxml`	Interfaces, including S-R, C-S, M-S, NV, parameter, and trigger interfaces. The interfaces include type-specific elements, such as S-R data elements, C-S operations, port-based parameters, or triggers.
`modelname_timing.arxml`	Timing model, including runnable execution order constraints.

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 more information, see Generate AUTOSAR 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');

Fore 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. Select one of the following values for SwCalibrationAccess DefaultValue:
- ReadOnly — Read access only.
- ReadWrite (default) — Read and write access.
- NotAccessible — Not accessible with measurement and calibration tools.
For more information, see Configure SwCalibrationAccess.
Control the direction of CompuMethod conversion for linear-function CompuMethods. Select one of the following values for CompuMethod Direction:
- InternalToPhys (default) — Generate CompuMethod sections for conversion of internal values into their physical representations.
- PhysToInternal — Generate CompuMethod sections for conversion of physical values into their internal representations.
- Bidirectional — Generate CompuMethod sections for both internal-to-physical and physical-to-internal conversion directions.
For more information, see Configure CompuMethod Direction for Linear Functions.
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.

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, CompuMethodDirection, and InternalDataConstraintExport. For example:

arProps = autosar.api.getAUTOSARProperties(hModel);
set(arProps,'XmlOptions','ImplementationTypeReference','NotAllowed');
set(arProps,'XmlOptions','SwCalibrationAccessDefault','ReadOnly');
set(arProps,'XmlOptions','CompuMethodDirection','PhysToInternal');
set(arProps,'XmlOptions','InternalDataConstraintExport',true);
