    MGSyn

    MGSyn

    MGSyn - Automatic Synthesis for Industrial Automation

    MGSyn (Model, Game, Synthesis) is an open-source tool which integrates game-based synthesis into model-driven development for industrial control and automation. It is served for research and educational purposes. MGSyn has been originally developed by Department of Informatics (Unit 6), TU München and fortiss GmbH and is now maintained by fortiss GmbH. The software is released under the GNU General Public License Version 3.0 (GPLv3). Please download the tutorial for step-by-step instructions on installing and using the tool. It is advised to use 32-bit version (Eclipse) associated in the "MGSyn supplementary files", as the 64-bit version will by default demand huge memory, which may lead to Java exceptions.
