IEC 61508:2010 defines how safety‑related software in industrial automation is developed and verified across SIL 1 to SIL 4. It recommends the certification of software tools in section 7.4.4 and outlines tool classification criteria in section 3.2.11. QA Systems verification tools are widely used in industrial domains, supporting coding standards such as MISRA, CERT, and CWE. Cantata, Cantata Hybrid, and QA‑MISRA have been certified by SGS‑TÜV Saar GmbH as class T2 offline support tools under IEC 61508 Part 3, making them suitable for verifying high‑integrity industrial safety software.
