Learning Objectives
Derive Safety Requirements
Turn HARA safety goals into verifiable functional safety requirements (FSRs).
Define Safe States & Timing
Design safe states, degradation modes, and calculate FTTI/FDTI timing budgets.
Build Fault-Tolerant Architectures
Apply redundancy, voting schemes, and CCF prevention for high-ASIL systems.
Write a Complete FSC Document
Structure and deliver a real FSC with full traceability using the ESC case study.
Chapters
What and How to Develop a FSC
