Syntax

[model,status] = createCompositionAsModel(ar,CompositionName)
[model,status] = createCompositionAsModel(ar,CompositionName,Name=Value)

Description

[model,status] = createCompositionAsModel(ar,CompositionName) creates a Simulink® model that corresponds to the AUTOSAR atomic software composition CompositionName, and returns a handle to the model, represented by model, and a status indicating whether the action was successful, represented by status.

The composition description is part of AUTOSAR information previously imported from AUTOSAR XML (ARXML) files that are represented by the arxml.importer object ar. The importer creates an initial Simulink representation of the imported AUTOSAR composition. The initial representation provides a starting point for further AUTOSAR configuration and Model-Based Design. For more information, see AUTOSAR ARXML Importer.

example

[model,status] = createCompositionAsModel(ar,CompositionName,Name=Value) specifies additional options for Simulink model creation using one or more name-value arguments. For example, to direct the importer to model AUTOSAR periodic runnable as atomic subsystems with periodic rates, set ModelPeriodicRunnablesAs to "AtomicSubsystem".

Import AUTOSAR software composition /Company/Components/ThrottlePositionControlComposition from ARXML file ThrottlePositionControlComposition.arxml, and create an initial Simulink representation of the composition.

openExample("ThrottlePositionControlComposition.arxml");
ar = arxml.importer("ThrottlePositionControlComposition.arxml");
names = getComponentNames(ar,"Composition")
names =
  1×1 cell array
    {'/Company/Components/ThrottlePositionControlComposition'}
createCompositionAsModel(ar,"/Company/Components/ThrottlePositionControlComposition");

Import AUTOSAR software composition /pkg/rootComposition from ARXML file mySWCs.arxml and create an initial Simulink representation of the composition. For components mySwc1 and mySwc2 contained within the composition, use existing Simulink component models rather than creating new ones.

ar = arxml.importer("mySWCs.arxml")
createCompositionAsModel(ar,"/pkg/rootComposition",ComponentModels={"mySwc1","mySwc2"})

Import AUTOSAR software composition /pkg/rootComposition from ARXML file mySWCs.arxml and create an initial Simulink representation of the composition. Import Simulink data objects corresponding to AUTOSAR data types to data dictionary ardata.sldd.

ar = arxml.importer("mySWCs.arxml")
createCompositionAsModel(ar,"/pkg/rootComposition",DataDictionary="ardata.sldd")

Import AUTOSAR software composition /Company/Components/ThrottlePositionControlComposition from ARXML file ThrottlePositionControlComposition.arxml, and create an initial Simulink representation of the composition.

For each imported component, the importer stores shareable AUTOSAR component properties, such as interfaces and data types, in data dictionary ardata.sldd. Components within the composition can then share the stored properties.

openExample("ThrottlePositionControlComposition.arxml");
ar = arxml.importer("ThrottlePositionControlComposition.arxml")
createCompositionAsModel(ar,"/Company/Components/ThrottlePositionControlComposition",...
    ModelPeriodicRunnablesAs="Auto",...
    DataDictionary="ardata.sldd",ShareAUTOSARProperties=true);

To view the shared properties, open the AUTOSAR Dictionary of a component model. This example opens ThrottlePositionSensor. Expand the AUTOSAR Dictionary node ardata.sldd. You can view read-only properties, such as shared component interfaces, and modify XML options for composition and component export.

autosar_ui_launch("ThrottlePositionSensor")

AUTOSAR Dictionary dialog box. The ardata.sldd node is expanded.

Import AUTOSAR software composition /pkg/rootComposition from ARXML file mySWCs.arxml and create an initial Simulink representation of the composition. Model AUTOSAR periodic runnables as function-call subsystems with periodic rates.

ar = arxml.importer("mySWCs.arxml")
createCompositionAsModel(ar,"/pkg/rootComposition",...
  ModelPeriodicRunnablesAs="FunctionCallSubsystem")

Import AUTOSAR software composition /pkg/rootComposition from ARXML file mySWCs.arxml and create an initial Simulink representation of the composition. Use predefined variant Senior to resolve variation points in components at model creation time.

ar = arxml.importer("mySWCs.arxml")
createCompositionAsModel(ar,"/pkg/rootComposition",...
  PredefinedVariant="/pkg/body/Variants/Senior");

Import AUTOSAR software composition /pkg/rootComposition from ARXML file mySWCs.arxml and create an initial Simulink representation of the composition. Use system constant values A and B to resolve variation points in components at model creation time.

ar = arxml.importer("mySWCs.arxml")
createCompositionAsModel(ar,"/pkg/rootComposition",...
  SystemConstValueSets={'/pkg/body/SystemConstantValues/A','/pkg/body/SystemConstantValues/B'});

Input Arguments

collapse all

AUTOSAR information previously imported from ARXML files, specified as an arxml.importer object handle.

Absolute short-name path of the software composition specified as a character vector or string scalar.

Example: "/Company/Powertrain/Components/RootComposition"

Name-Value Arguments

collapse all

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: createCompositionAsModel(ar,"/pkg/rootComposition",ModelPeriodicRunnablesAs="AtomicSusbsytem")

Names of existing atomic software component models to use when creating a Simulink representation of the composition, specified as a cell array of character vectors or a string array. The function incorporates the specified existing component models in the composition model instead of creating new ones.

Example: ComponentModels={"mySwc1","mySwc2"}

Simulink data dictionary to import data objects corresponding to AUTOSAR data types in the ARXML file into, specified as a character vector or string scalar. If the specified dictionary does not exist, the importer creates it. The model is then linked to that data dictionary.

If you specify true for the ShareAUTOSARProperties name-value argument, the specified data dictionary also stores shareable AUTOSAR component properties, such as interfaces and data types, for sharing among components in the composition.

Example: DataDictionary="ardata.sldd"

Subsystem type for periodic runnables, specified as "AtomicSubsystem", "FunctionCallSubsystem", or "Auto".

By default, createCompositionAsModel imports AUTOSAR periodic runnables found in ARXML files and attempts to model them as atomic subsystems with periodic rates. If conditions prevent use of atomic subsystems, the function models the periodic runnables as function-call subsystems with periodic rates.

To model periodic runnables only as atomic subsystems, specify "AtomicSubsystem". If conditions prevent use of atomic subsystems, the function throws an error.

To model periodic runnables only as function-call subsystems, specify "FunctionCallSubsystem".

For more information, see Import AUTOSAR Software Component with Multiple Runnables.

Example: ModelPeriodicRunnablesAs="AtomicSubsystem"

Path to a predefined variant in an ARXML file. A predefined variant describes a combination of system constant values among potentially multiple valid combinations to apply to AUTOSAR software components. Use this argument to resolve variation points in AUTOSAR software components at model creation time. If specified, the importer uses the predefined variant to initialize software system constant data that serves as input to control variation points.

For more information, see Control AUTOSAR Variants with Predefined Value Combinations.

Example: PredefinedVariant="/pkg/body/Variants/Senior"

Option to add AUTOSAR component properties to a shared data dictionary, specified as a numeric or logical 1 (true) or 0 (false). To share AUTOSAR component properties, specify ShareAUTOSARProperties as true and specify a Simulink data dictionary by using the DataDictionary name-value argument. For each imported component, the function stores shareable AUTOSAR component properties, such as interfaces and data types, in the Simulink data dictionary specified by using the DataDictionary name-value argument.

Sharing stored AUTOSAR component properties in a Simulink data dictionary can improve the performance of common tasks in AUTOSAR composition modeling. Once component properties are stored in a data dictionary, components within the composition can then share those stored properties. For compositions containing more than 20 software components, sharing AUTOSAR properties among components can significantly improve performance for composition workflows, including import, dictionary navigation, AUTOSAR validation, and code generation. Limiting property replication among components can also reduce component model file sizes.

The AUTOSAR Dictionary provides a central location for viewing and configuring AUTOSAR composition and component properties. You can view read-only properties, such as shared component interfaces, and modify XML options for composition and component export.

For more information, see Import AUTOSAR Composition and Share AUTOSAR Dictionary.

Example: ShareAUTOSARProperties=true

Paths to one or more system constant value sets defined in the ARXML file, specified as a cell array of character vectors or a string array. A system constant value set specifies a set of system constant values to apply to AUTOSAR software components. Use this argument to resolve variation points in AUTOSAR software components at model creation time. If specified, the importer uses the system constant value sets to initialize software system constant data that serves as input to control variation points.

For more information, see Control AUTOSAR Variants with Predefined Value Combinations.

Example: SystemConstValueSets={'/pkg/body/SystemConstantValues/A','/pkg/body/SystemConstantValues/B'}

Option to import client-server ports as Simulink function ports, specified as numeric or logical 1 (true) or 0 (false).

  • true — Use port-scoped Simulink functions and function callers.

  • false — Use global Simulink functions and function callers.

Example: UseFunctionPorts=true

Data Types: logical

Option to import AUTOSAR data types as Simulink.ValueType data type objects, specified as numeric or logical 1 (true) or 0 (false).

Example: UseValueTypes=true

Data Types: logical

Output Arguments

collapse all

Handle of the model that corresponds to the specified AUTOSAR software composition CompositionName.

Success or failure status of the import, returned as one of these values:

  • true — The import was successful.

  • false — The import was not successful.

Tips

If you enter the arxml.importer object function call without a terminating semicolon, the importer lists the AUTOSAR content of the specified ARXML file or files. The information includes paths to software components in the AUTOSAR package structure, which you can specify in calls to importFromARXML and createComponentAsModel.
