Hello,
I am performing a Processor-in-the-Loop (PIL) simulation on a control subsystem of a fuel-cell model using Simulink/Simscape and an STM32F429 target with Embedded Coder.
I used the option "Create SIL/PIL block" for the subsystem, followed by C/C++ Code > Build This Subsystem, and then added the generated block to my model for testing(fuel-cell model).
When I run the simulation, I get the following warning:
"Top model does not contain a referenced model. ‘Simulation’ and ‘SIL/PIL Simulation’ will behave in the same way. Change ‘system under test’ or add a model block to the top model."
At the same time, the simulation output curves for normal simulation and PIL are identical (confondues), which is expected, but this warning makes me unsure.
My questions:
Does this warning indicate that the PIL simulation is not actually running on the target hardware?
Since I’m testing only a control subsystem using a PIL block, and not the entire model, is it safe to ignore this warning?
Do I need to replace the subsystem with a referenced model (Model block) to properly use PIL at the top level?
Thank you in advance for your help!Hello,
