The coverage-plugin is a C++ project using the Model Trace Interface Plugin Development Kit (MTIPDK) in order to create a trace plugin, which is a special shared library. The trace plugins can be loaded into Arm Fast Models to produce execution trace data for doing code coverage measurement.
$ cd coverage-plugin $ make PVLIB_HOME=</path/to/model_library>
You need to add two options to your model command-line:
--plugin /path/to/coverage_trace.so -C TRACE.coverage_trace.trace-file-prefix="/path/to/TRACE-PREFIX"
You can then run your FVP model. The traces will be created at the end of the simulation*.
BEWARE: Traces aren't numbered and will be overwritten if you do two successive runs. Aggregating results will require moving traces to a separate place or changing the prefix between runs. This is the responsibility of the plugin user.
*NOTE: The plugin captures the traces in memory and on the termination of the simulation it writes the data to a file. If user terminates the simulation forcefully with a Ctrl+C the trace files are not generated.
