xDEVS stands for A cross-platform (x) Discrete EVent System simulator. This library includes a set of C, C++, C#, Go, Java, Python and Rust repositories that provide an event-driven simulation interface. This interface follows the formalism Discrete Event System Specification (DEVS). The project final goal is to elaborate the fastest DEVS simulation interface with capacity to simulate models in virtual and real time, and to run simulations in sequential (single-threaded), parallel (multi-threaded) and distributed (not shared memory) architectures.
Research in the xDEVS interface can be found in xDEVS: A toolkit for interoperable modeling and simulation of formal discrete event systems. Please, cite our article in case you find xDEVS useful. This way we can gain visibility:

There are seven repositories associated with xDEVS, each one offering the equivalent simulation interface for each corresponding programming language.
- xDEVS/C (xdevs.c)
- xDEVS/C++ (xdevs.cpp)
- xDEVS/C# (xdevs.cs)
- xDEVS/Go (xdevs.go)
- xDEVS/Java (xdevs.java) - API documentation
- xDEVS/Python (xdevs.py)
- xDEVS/Rust (xdevs.rs)
- xDEVS/Rust for embedded systems (xdevs_no_std.rs)
All the repositories are included as submodules inside this main repository.
The xDEVS user’s manual can be found here.
- PDEVS Modeling and Simulation formalism
- Object-Oriented Programming
- Support for sequential, parallel and distributed (this last feature only in Java and Python, for now) architectures.
- Good performance, compared to other simulation engines
