Simulink calls the stepImpl, outputImpl, and updateImpl methods multiple times during simulation at each time step. Simulink typically calls other methods once per simulation.

The Simulink engine calls the isOutputFixedSizeImpl, getDiscreteStateSpecificationImpl, isOutputComplexImpl, getOutputDataTypeImpl, getOutputSizeImpl when using propagation methods.

Simulink calls saveObjectImpl and loadObjectImpl for saving and restoring SimState, the Simulation Stepper, and Fast Restart.

Default implementations save and restore all properties with public access, including DiscreteState.
