Create AUTOSAR Adaptive software component models in Simulink^® by using one of these methods:

• Import ARXML files with arxml.importer and using the createComponentAsModel function. For an example, see Import AUTOSAR Adaptive Components to Simulink.

• Create a Simulink model algorithm with blocks and signals and then configuring the model as an AUTOSAR Adaptive software component with the AUTOSAR Component Designer app. For more information, see Model AUTOSAR Adaptive Component and Elements in Simulink.

• Create and configure an AUTOSAR Adaptive software component from an existing Simulink model.

In this tutorial, you create model my_autosar_LaneGuidance from Simulink model LaneGuidance.

For your reference, you can open example model autosar_LaneGuidance to check your work and explore a configured AUTOSAR Adaptive software component model.

1. Open example model LaneGuidance:

   openExample("LaneGuidance");

2. Set configuration parameter System target file to autosar_adaptive.tlc. This system target file enables AUTOSAR Blockset software and sets these configuration parameters in the model:

   Configuration Parameter	Value
   Language	C++
   Toolchain	AUTOSAR Adaptive | CMake
   Code replacement library	C++ Standard Library Mutex
   Array container type	std::array
   AUTOSAR schema version	R22-11
   Maximum short name length	128

3. Verify the solver settings, which determine the execution period of the generated code. The fixed-step size directly controls the periodic task rate in the main.cpp file that is generated in the last step of this tutorial.

   Configuration Parameter	Value
   Type	Fixed-step
   Solver	auto (Automatic solver selection)
   Fixed-step size	0.2
   Periodic same time constraint	Unconstrained

4. Examine the bus element ports that model event-based data communication in the model. The model consists of a subsystem, LaneGuidanceAlgorithm, with In Bus Element and Out Bus Element blocks.

   Port	Elements
   LeftSensor	LaneDistance TurnIndicator CarInBlindSpot
   RightSensor	LaneDistance TurnIndicator CarInBlindSpot
   HazardIndicator	Left Right

5. Save the model to a writable folder on your current MATLAB^® search path. Name the file my_autosar_LaneGuidance.slx.
