autosar.arch.Composition

R2026b

AUTOSAR software composition in architecture model

Description

An autosar.arch.Composition object represents an AUTOSAR software composition in an AUTOSAR software architecture model. An AUTOSAR composition is a container that groups AUTOSAR software components and nested compositions into a hierarchical software architecture.

Creation

Create an autosar.arch.Composition object by using the addComposition function on an autosar.arch.Model or autosar.arch.Composition object.

composition = addComposition(archModel,"MyComposition")

composition =

  Composition with properties:

              Name: 'MyComposition'
    SimulinkHandle: 6.0001
            Parent: [1×1 autosar.arch.Model]
        Components: [0×0 autosar.arch.Component]
      Compositions: [0×0 autosar.arch.Composition]
             Ports: [0×0 autosar.arch.CompPort]
        Connectors: [0×0 autosar.arch.Connector]
          Adapters: [0×0 autosar.arch.Adapter]
     ReferenceName: ''

Properties

Examples

Create AUTOSAR Software Architecture with AUTOSAR Compositions

Create an architecture model and add a composition.

archModel = autosar.arch.createModel("VehicleArch");
sensorGroup = addComposition(archModel,"SensorGroup");

Add components inside the composition.

tempSensor = addComponent(sensorGroup,"TempSensor");
pressureSensor = addComponent(sensorGroup,"PressureSensor");

Add ports to the composition and internal components, and connect them.

addPort(tempSensor,"Sender","TempData");
addPort(pressureSensor,"Sender","PressureData");
addPort(sensorGroup,"Sender", {"TempData","PressureData"});

connect(sensorGroup,tempSensor,[]);
connect(sensorGroup,pressureSensor,[]);
