I am trying to generate HDL Code for Drive System of electrical 3-phase Motors, the model consists of parent Model and many of referenced models. no errors and no warnings in the model but when i use workflow advisor to generate the code, the generated code is alwayes failed and this is the cause:

This error is unexpected from HDL Coder that happens when the DUT / referenced model has zero input and output ports. Such subsystems do not contribute to logic and lead to this error instead of a valid message with instructions. Consider adding atleast one output port that contributes to logic to workaround this error.
