Reactis plays a number of important roles in a model-based design process. It gives you a set of tools to test, verify, and truly understand your model's behavior and can help you check whether the source code that will ultimately be deployed conforms to the behavior of your model. More on testing and validation of Simulink models.
Reactis for EML Plugin integrates seamlessly with Reactis to offer white-box testing of any portions of your model implemented with Embedded MATLAB®, e.g. MATLAB Function blocks and the MATLAB action language in Stateflow.
Reactis for C Plugin integrates seamlessly with Reactis to offer white-box analysis of the C code portions of models (C Caller blocks, S-Functions and Stateflow custom code). More on C Caller block, S-Function, and custom code debug.
Reactis and the C Plugin also support testing TargetLink® models and C code.
Reactis Model Inspector offers a low-cost, lightweight Simulink viewer.
Reactis for C generates comprehensive yet compact tests from C code, detects runtime errors, and tracks coverage (Statement, Decision, Condition, MC/DC, MCC). When an error is detected, you can easily replay a concrete execution sequence leading to the problem in order to understand, diagnose, and fix the bug. More on testing C code.
