Simulink Fault Analyzer
Simulink Fault Analyzer enables systematic fault effect and safety analysis through simulation.
It performs fault injection simulations without altering the original design, allowing faults to be triggered by specific system conditions or scheduled over time. You can manage and simulate faults modeled in Simulink, Simscape, and System Composer, and analyze their effects using the Simulation Data Inspector. Fault sensitivity analyses can be conducted through the Multiple Simulations panel, while safety assessments—such as Failure Mode and Effects Analysis (FMEA)—can be performed directly within the simulation environment.
Simulink Fault Analyzer also allows you to establish formal links between faults, hazards, detection and mitigation logic, and other related artifacts when used with Requirements Toolbox.
Model Faults
Inject faults and other abnormal behavior onto Simulink signals without modifying your model. Define complex fault behavior such as noise and delays. Configure fault injection triggers based on simulation time and system conditions.
Analyze Fault Effects
Use the Simulation Data Inspector to analyze the effects of faults on your design. Log fault activity and monitor system conditions of interest, such as hazards.
Perform Systematic Safety Analyses
Conduct safety analyses per standards such as ISO 26262, such as Failure Mode and Effects Analysis (FMEA), using design and simulation artifacts.
Manage Faults Across Domains
Configure and manage faults modeled in Simulink, Simscape, and System Composer.
Conduct Fault Sensitivity Studies
Analyze how effective your fault detection and fault mitigation strategies are when fault behavior varies or when multiple faults are injected via simulation during design studies.
Generate Fault Specification Reports
Export fault modeling information and create custom fault specification reports.
