FTTI Explorer
The Fault Tolerant Time Interval (ISO 26262 Part 1) is the time a system can tolerate a fault before a hazardous event occurs. It is the budget every safety mechanism must fit inside: detect the fault, react, and reach a safe state — before physics catches up with you. FTTI drives safety-mechanism design more than almost any other number in a safety concept: it decides your monitoring cycle times, your watchdog windows, and whether your actuator is fast enough at all. Move the sliders and watch the fault-handling timeline race the hazard boundary.
I build simulation tools like this, tailored to your vehicle and your safety case — from FTTI determination on real vehicle-dynamics models to requirement traceability apps your assessor can audit. See Safety Tooling & Simulation, Built to Order.
