Safety & Compliance

Paterion supports the key safety standards for regulated industries – with automatic MC/DC coverage and cartesian test generation.

MC/DC Coverage Explained

Modified Condition/Decision Coverage (MC/DC) is the gold standard for safety-critical systems. Paterion automatically generates the required cartesian test coverage.

Union Mode

Independent treatment of parallel branches. Fast generation for lower safety levels.

Cartesian Mode

All combinations of parallel branches. Required for highest safety levels (ASIL D, DAL A/B).

Background Generation

Large cartesian expansions run in the background with progress tracking – up to 10,000 paths.
