Unspecified inheritability of sample time


Select the diagnostic action to take if this model contains S-functions that do not specify whether they preclude this model from inheriting their sample times from a parent model.

Category: Diagnostics


Default: warning


Simulink® software takes no action.


Simulink software displays a warning.


Simulink software terminates the simulation and displays an error message.


  • Not specifying an inheritance rule may lead to incorrect simulation results.

  • Simulink software checks for this condition only if the solver used to simulate this model is a fixed-step discrete solver and the periodic sample time constraint for the solver is set to ensure sample time independence

  • For more information, see Periodic sample time constraint.
