Hi @aleFerrari , the Raman simulation is currently not covered by automated tests (this is visible in the coverage report saying "codecov/project 65.59% (-13.82%) compared to 71d6a11*).

It would be nice if there is a simple test checking that the simulation engine works well. I think that the scenario should be kept reasonably simple, with just a few signals being checked and with a simplified topology (just one link). I'll be happy to help.
