Ansys medini analyze vs Astah GSN

Both cited pages name ISO 26262. Medini implements HAZOP, HARA, FTA and FMEA/FMEDA and also names IEC 61508 and ARP 4761. Astah draws GSN safety-case arguments and names automotive (ISO 26262). Not a recommendation.

Built only from the cited fields already on Ansys medini analyze and Astah System Safety (GSN). Not a ranking, certification or recommendation. Public summary columns stay on this page. Quoted evidence, who-it-is-for, deployment, caveats and coverage-cell quotes are Pro.

Questions

Do both listings tag ISO 26262 from the cited page?

Yes. Medini’s product page names ISO 26262 among the standards it is tailored to. Astah’s GSN page names automotive (ISO 26262). Tags are from those sentences, not certificates.

What does each cited page actually do?

Medini is model-based safety analysis (HAZOP, HARA, FTA, FMEA/FMEDA). Astah is GSN modeling with SysML and STPA/STAMP. Neither cited page is a neural-network verifier.

Does naming ISO 26262 mean either tool certifies a vehicle AI function?

No. Framework tags mean the cited page names that instrument. ISO 26262-1 addresses malfunctioning E/E behaviour in series-production road vehicles. ISO/PAS 8800 is the AI-scoped companion and is not tagged from these pages.
