error

Simulink software terminates code generation and displays an error message.

Tips

  • A parameter downcast occurs if the computation of block output required converting the parameter's specified type to a type having a smaller range of values (for example, from uint32 to uint8).

  • This diagnostic applies only to named tunable parameters (parameters with a non-Auto storage class).
