Bridging Safety and Architecture: Zephyr’s Path To IEC 61508 Complian...
summary
Zephyr is pursuing IEC 61508 compliance by scoping safety to kernel services (~15,000 lines of code) and targeting SIL3 target reasoning, with a safety committee, working group and a TUV-validated concept report. Work products include coding guidelines (MISRA subset), integration of static analyzers (ECLAIR, cppcheck), and a safety manual template; remaining gaps are a requirements repo, traceability from hazards to tests, and handling Kconfig feature management plus in-tree codegen/CMake/linker dependencies for verification in virtualized tests.
