What is Reactis?

Reactis is a tool suite from Reactive Systems, Inc. that automatically generates test suites for Simulink® and Stateflow® models and for C code. It tracks coverage (including MC/DC), flags run-time errors, checks models against requirements, and compares code with the model it came from in back-to-back tests. TÜV SÜD has certified that Reactis is qualified for safety-related development according to ISO 26262, up to ASIL D.

Teams in automotive, aerospace and medical-device development use Reactis to find defects early and to document coverage for standards such as ISO 26262 and DO-178C.
