Detect read before write
Select the diagnostic action to take if the model attempts to read data from a data store to which it has not written data in this time step.
Use local settings
For each local data store (defined by a Data Store Memory block or
Simulink.Signalobject in a model workspace) use the setting specified by the block. For each global data store (defined by a
Simulink.Signalobject in the base workspace) disable the diagnostic.
Disables this diagnostic for all data stores accessed by the model.
Enable all as warnings
Displays diagnostic as a warning at the MATLAB® command line.
Enable all as errors
Halts the simulation and displays the diagnostic in an error dialog box.
During model referencing simulation in accelerator and rapid
accelerator mode, if the Detect read before write parameter
is set to
Enable all as warnings,

You can use the Model Advisor to identify referenced models for which Simulink changes configuration this parameter setting during accelerated simulation.
In the Simulink Editor, in the Modeling tab, click Model Advisor, then click OK.
Select By Task.
Run the Check diagnostic settings ignored during accelerated model reference simulation check.
