The tooling

The Sim4Sys toolchain is composed of two main parts:

1. Sim4Sys-Designer is a desktop tool build on Papyrus, an open source UML/SysML tool develop in Java on Eclipse platform. The Papyrus lead is the French organisation CEA-Tech.
2. Sim4Sys-VB is a Node Javascript application running at https://sim4sys.com that is accessed through a Chrome webbrowser.

Sim4Sys-Designer is used to design some UML/SysML models. After creating their models, the engineers can generate a C++ code that is another view on the logical behavior described in the models. After being compiled, the code can be excuted and used to control the behavior of some graphical objects present in Sim4Sys-VB simulation tool. The behavior in the virtual world is the one described in the models : test scenarios can be defined in Sim4Sys-VB to verify and validate the behavior design.
