Select the diagnostic action to take when the software detects a Merge block with more than one driving block executing at the same time step.
Simulink® software takes no action.
Simulink software displays a warning.
Simulink terminates the simulation and displays an error message only if the execution order of the driving blocks is not explicitly defined.
Connecting the inputs of a Merge block to multiple driving blocks that
execute at the same time step can lead to inconsistent results for both
simulation and generated code. Set Detect multiple driving blocks
executing at the same time step to
error to avoid such situations.
