Code Coverage for Models in Software-in-the-Loop (SIL) Mode and Processor-in-the-Loop (PIL) Mode
If you have Embedded Coder® and Simulink® Coverage™, you can analyze coverage for generated code during a software-in-the-loop (SIL) or processor-in-the-loop (PIL) simulation.
Enable SIL or PIL Code Coverage for a Model
To record SIL or PIL code coverage for a model:
Ensure you have a supported compiler installed. For a list of supported compilers, see Supported and Compatible Compilers.
In the Configuration Parameters dialog box, on the left pane, click Code Generation. From the list, select Verification.
Under Code profiling, set Measure function execution times to
Under Code coverage for SIL or PIL, set Third-party tool to
None (use Simulink Coverage).
Enable coverage for a model in SIL or PIL mode or a reference model in SIL or PIL mode.
Run a SIL or PIL simulation.
The Coverage (Run) button in the Coverage toolstrip forces a Normal mode simulation for the top-level model and does not yield SIL or PIL code coverage.
To run a SIL or PIL simulation:
In the Simulink window, click Apps and then click SIL/PIL Manager.
In the SIL/PIL tab, click Automated Verification > SIL/PIL Simulation Only.
Click Run SIL/PIL.
Review the Coverage Results for Models in SIL or PIL Mode
To view the code coverage information in the Code view, from the drop-down list to the right of the search box, select Show code coverage. If the option is disabled, then on the Coverage tab, click Coverage Highlighting. The code displays highlighting and annotations that show code coverage information. You can navigate from the code to the associated model blocks by using the links in the line numbers, code elements, and comments.
At the bottom of the Code view, the coverage section shows a summary of the code coverage report.
Coverage for models in SIL and PIL mode has these limitations:
The model must meet the requirements listed in Enable SIL or PIL Code Coverage for a Model.
Code coverage results must not include external C/C++ files in read-only folders.
The Coverage (Run) button in the Coverage toolstrip forces a Normal simulation and will not yield SIL or PIL code coverage.
