Fault Simulation

Simulate faults in models to analyze model responses

Use Simulink^® Fault Analyzer™ to simulate faults and conditionals. Conduct fault exploration with Multiple Simulations. Compare simulation results and inspect fault effects by using the Simulation Data Inspector.

Tools

Multiple Simulations	Run multiple simulations from the Simulink Editor (Since R2021b)
Simulation Data Inspector	Inspect and compare data and simulation results to validate and iterate model designs
Simulation Manager	Monitor multiple simulations and visualize the simulation data

Functions

`activate`	Set fault as active fault (Since R2023b)
`Simulink.fault.enable`	Enable or disable faults on model elements (Since R2023b)
`Simulink.fault.injection`	Enable fault simulation for model (Since R2023b)
`Simulink.fault.isEnabled`	Determine whether model elements are enabled for fault injection (Since R2023b)

Objects

`Fault`	Create or modify faults in models (Since R2023b)
`Conditional`	Create or modify conditionals in models (Since R2023b)
`Symbol`	Create or modify symbols in conditionals (Since R2023b)
