Reactis data
File type: Various data file
An rsi file extension identifies data used by Reactis, a model-based testing application for Simulink and Stateflow models.
The file is part of Reactis's internal data rather than a general-purpose document format.

The rsi file extension is associated with Reactis, software from Reactive Systems for model-based testing, debugging, and validation of Simulink and Stateflow models.
An rsi file stores data that Reactis uses internally while working with those models and testing projects. It is a supporting file for the Reactis environment, not the model itself.
Reactis is available for Microsoft Windows. The format is intended for use by Reactis and may not be suitable for independent use or editing.
Use Reactis on Microsoft Windows to work with an rsi file. These files are not generally intended to be opened directly as documents, and their contents should not be edited with a text editor.
There is no generally applicable converter for the Reactis rsi file format. Because the file contains internal Reactis data, it should normally be kept with the related Reactis project or data rather than converted separately.
