After you create an AUTOSAR architecture model, develop the top-level AUTOSAR software design. The composition editor provides a view of AUTOSAR software architecture based on the AUTOSAR Virtual Function Bus (VFB).
Starting at the top level of the architecture model, use the composition editor and the Simulink® Toolstrip Modeling tab to add and connect AUTOSAR software compositions and components. See Add and Connect AUTOSAR Compositions and Components.
If you have an ARXML description of an AUTOSAR software composition, you can import the composition into an AUTOSAR architecture model. The import creates a Simulink representation of the composition at the top level of the architecture model.
Composition import requires an open AUTOSAR architecture model with no functional
content. To import a composition, open the AUTOSAR Importer app or call the architecture
To import an AUTOSAR software composition from ARXML files into an architecture model:
Create or open an AUTOSAR architecture model that has no functional content. For example, enter this MATLAB® command:
archModel = autosar.arch.createModel("myArchModel");
In the open architecture model, on the Modeling tab, select Import from ARXML.
In the AUTOSAR Importer app, in the Select ARXML pane, in the ARXML Files field, enter the names of one or more ARXML files (comma separated) that describe an AUTOSAR software composition.
For this example, enter
ThrottlePositionControlComposition.arxml. The ARXML
file is located at
which is on the default MATLAB search path.
Click Next. The app parses the specified ARXML file.
In the Create Composition pane, the
Composition name menu lists the compositions found
in the parsed ARXML file. Select the composition
Optionally, to view additional modeling options for composition creation, select Configure Modeling Options.
You can specify:
Whether to include or exclude AUTOSAR software components, which define composition behavior. By default, the import includes components within the composition.
Simulink data dictionary in which to place data objects for imported AUTOSAR data types.
Names of existing Simulink behavior models to link to imported AUTOSAR software components.
Component options to apply when creating Simulink behavior models for imported AUTOSAR software
components. For example, how to model periodic runnables, or a
SwSystemconstantValueSets with which to
resolve component variation points.
For more information about modeling options and behavior, see
To finish importing the composition into the architecture model, click Finish. The Diagnostic Viewer displays the progress of the composition creation.
On completion, the imported composition appears in the software architecture canvas.
Because this composition import was configured to include AUTOSAR software components (modeling option Exclude internal behavior from import was cleared), the import created Simulink models for each component in the composition.
Next you develop each component in the composition. For each component model, you refine the AUTOSAR configuration and create algorithmic model content. For an example of developing component algorithms, see Design and Simulate AUTOSAR Components and Generate Code, section "Develop AUTOSAR Component Algorithms".
To programmatically import an AUTOSAR software composition from ARXML files into
an architecture model, call the
importFromARXML function. This example:
