Model AUTOSAR Runnables Using Exported Functions
Use Simulink® exported functions to model AUTOSAR runnables.
Multiple Periodic Runnables Configured for Function Export
Open the example model
The model shows the implementation of an AUTOSAR atomic software component (ASWC) using export-function modeling. Export-function models are Simulink models that generate code for independent functions. You can integrate the independent function code with an external environment and scheduler. Functions typically are defined using Function-Call Subsystem and Simulink Function blocks.
This model implements three AUTOSAR periodic runnables using Function-Call Subsystem blocks that have periodic rates. The runnables have sample rates of 1 second, 1 second, and 10 seconds, respectively. To display color coded sample rates with annotations and a legend, on the Debug tab, select Diagnostics > Information Overlays > Colors.
Simulink signal lines model AUTOSAR inter-runnable variables (IRVs), which connect the runnables.
Generate AUTOSAR Component Code and XML Descriptions (Embedded Coder)
If you have Simulink Coder and Embedded Coder software, you can generate algorithmic C code and AUTOSAR XML (ARXML) component descriptions. You can test the generated code in Simulink or integrate the code and descriptions into an AUTOSAR run-time environment.
For example, to build the
autosar_swc_expfcns component model, open the model. Press Ctrl+B or enter the MATLAB command
slbuild('autosar_swc_expfcns'). When the build completes, a code generation report opens.
In the code generation report, select the Code Interface Report section, and examine the Entry-Point Functions table.
In the generated code, each root-level function-call Inport block generates a void-void function. From generated file
autosar_swc_expfcns.c, here is the generated code for
