Select how Simulink® software handles initialization of initial conditions for conditionally executed subsystems, Merge blocks, subsystem elapsed time, and Discrete-Time Integrator blocks.
Initial conditions are initialized the same way they were prior to R2008b.
Initial conditions are initialized using the enhanced behavior, which can improve the consistency of simulation results.
Classic to ensure compatibility with
previous releases of Simulink.
Simplified to improve the consistency of
simulation results, especially for models that do not specify initial
conditions for conditional subsystem output ports, and for models that have
conditionally executed subsystem output ports connected to S-functions. For
more information, see Simplified Initialization Modeand Classic Initialization Mode.
For existing models, MathWorks® recommends using the Model Advisor to migrate your model to the new settings. To migrate your model to simplified initialization mode, run the following Model Advisor checks:

mode, you must set Bus signal treated as vector to
error on the Connectivity Diagnostics
Classic enables the following
Detect multiple driving blocks executing at the same time step
Check undefined subsystem initial output
Check runtime output of execution context
Simplified disables these parameters, and
automatically sets Detect multiple driving blocks executing at the same
time step to
