Safety Analysis SimulatorsMaster FTA, FMEA, FMEDA & Markov Chains
Professional interactive simulators for automotive functional safety analysis. Build fault trees, conduct FMEA studies, calculate hardware metrics, evolve continuous-time Markov chains, and verify ISO 26262 compliance with industry-standard tools. The Markov Chain Simulator is free for all registered users.
FTA Simulator
Fault Tree Analysis
Drag-and-drop fault tree builder for quantitative reliability analysis. Computes minimal cut sets with MOCUS and the full set of importance measures (Birnbaum, Fussell-Vesely, RAW, RRW) per IEC 61025. Use it to quantify top-event probability and rank basic events by contribution before committing to a hardware architecture.
FMEA Simulator
Failure Mode & Effects Analysis
AIAG-VDA FMEA workbench with automatic RPN scoring and SรO / SรD / OรD risk matrices. Linked to ISO 26262 safety goals, FSC and TSC so failure modes trace back to ASIL and PMHF targets. Use it to prioritize design FMEA actions or scaffold an FMEA-MSR for diagnostic and system-response coverage.
FMEDA Simulator
Hardware Safety Analysis
Click-through TCU power-supply schematic with failure modes and diagnostic coverage values from ISO 26262-5 Annex D. Computes SPFM, LFM and PMHF live as you swap safety mechanisms or switch between a preliminary and an ASIL-C compliant variant. Use it to find architecture gaps before you commit to a board layout.
Markov Chain Simulator
Continuous-Time Markov Reliability (Free for registered users)
Continuous-Time Markov Chain simulator that derives SPFM, LFM and PMHF straight from the generator matrix Q per ISO 26262-5 Annex C/F. Ships with three worked examples โ 1oo2 braking (ASIL D), ADAS sensor fusion (ASIL B), BMS dormant faults (ASIL C) โ and re-solves P(t)=e^Qt live as you tune ฮป, DC, CCF and repair rates. Free for every registered user.
Why Use Our Safety Simulators?
Learn by Doing
Hands-on practice with real automotive safety scenarios. Build fault trees, conduct FMEA studies, analyze hardware failures, and evolve Continuous-Time Markov Chains for braking, ADAS and BMS systems in a risk-free environment before applying to real projects.
Instant Feedback
Real-time calculation of safety metrics, validation errors, and compliance status. See immediate results as you modify your analysis, helping you understand the impact of each change.
Industry Standards
Tools built according to ISO 26262, AIAG-VDA FMEA, IEC 61025 (FTA) and IEC 61508 (CTMC reliability modelling) standards. Markov metrics follow ISO 26262-5 Annex C (SPFM, LFM) and Annex F (PMHF) exactly. Use the same methodologies and calculations that professional safety engineers use in production environments.
Export & Share
Save your analyses as JSON files, export reports, and share with your team. Use the simulators for documentation, presentations, and as reference implementations for your projects.
Visual Analysis
Interactive visualizations including fault tree diagrams, risk matrices, hardware schematics, and system hierarchies. Understand complex relationships at a glance with professional-grade graphics.
