Reactis Simulator enables users to visualize model execution. Simulator's user interface is similar to those of traditional debuggers from programming languages: it allows users to step through the execution of models by hand as well as set break points. Simulator also supports reverse execution, the replay of tests generated by Reactis Tester, the graphical display of different coverage metrics, and the capability to fine-tune Tester-generated test suites.

With Reactis for EML Plugin these advanced debug capabilities extend beyond Simulink and Stateflow and into Embedded MATLAB code. Step seamlessly from Simulink into a MATLAB Function block and set break points and track coverage in the Embedded MATLAB code.
