S32M244 Code Coverage

KOTRIKEADITHYA — Wed, 17 Dec 2025 05:08:06 GMT

Hi,

I am trying to enable the code coverage option in the debuggers using GHS compiler to check whether functions are executed or not.

Could you lease let know which debuggers will support code coverage when using the GHS compiler.

Thanks in advance.

Hello,

Please see the brief results for your case:

Green Hills MULTI IDE + G‑Cover
- Integrated tool for object-level code coverage (functions, branches, statements) without instrumentation.
TimeMachine Profiler
- Part of MULTI suite; provides execution profiling and coverage visualization using trace data.
VectorCAST
- External testing tool that integrates with GHS for automated unit/integration coverage analysis.
TRACE32 (Lauterbach)
- Advanced debugger; supports GHS symbols but does not provide built-in coverage metrics.

Best regards,

Peter

Hi,

I would like to understand the possible approaches to obtain code coverage using Lauterbach TRACE32 when building with the GHS compiler, as in build coverage is not available. is it feasible to achieve code coverage using any debugger -based mechanism in this case?

Additionally, with GCC compiler, is in build code coverage supported and compatible with Lauterbach TRACE32?

I am currently working on the NXP S32M244 microcontroller.

Thank you for your assistance and valuable inputs.

Looking forward to your guidance.

Best Regards,

K. Adithya

Please get in touch with Laterbach directly. As this is not NXP product.

https://support.lauterbach.com/

Yes, GCC supports in‑build coverage (gcov) via --coverage or -fprofile-arcs -ftest-coverage. This produces .gcno/.gcda files that you post‑process with gcov, llvm‑cov gcov, or gcovr. TRACE32 can coexist with such instrumented builds (you can still debug/trace them), but TRACE32 does not read .gcda/.gcno itself — you use gcov tooling to compute/report coverage.

But again, such is question for Lauterbach support.

Best regards,
Peter

Hi,

Could you please let me know how code coverage for functions and branches can be achieved on the NXPS32M244 controller using MULTI + G-Cover?

I would like to understand whether this is supported with the GHS compiler and what prerequisites are required for the setup.

Additionally, please share the detailed procedure to enable coverage and generate the coverage report using MULTI and G-Cover.

Thank you in advance.
