What is DEVSimPy?

DEVSimPy is an open-source framework (GPL v3) designed for modeling and simulating discrete event systems (DEVS) with a graphical user interface. Developed in Python with wxPython, it simplifies interaction with PyDEVS and PyPDEVS models.

Key Features 🚀

Feature	Description
Graphical Modeling	Design, save, and export DEVS models easily.
Simulation & Analysis	Run, suspend, and analyze simulations in real-time.
Code Editing	Modify DEVS models on the fly.
Model Libraries	Import/export libraries for domain-specific applications.
Command-Line Execution	Run simulations via CLI with devsimpy-nogui.py.
Plugin System	Extend functionality with custom plugins.
YAML Export	Generate YAML models for DEVSimPy-mob.
REST API	Enable remote simulation execution via DEVSimPy-REST.

Installation

Requirements

• Python 3.10+
• wxPython 4.0+
• SciPy & NumPy (for spectrum analysis, optional)

Standard Installation

$ git clone --recurse-submodules -b version-4.0 --depth=1 https://github.com/capocchi/DEVSimPy.git
$ git fetch --unshallow
$ pip install -r requirements.txt

Running DEVSimPy

$ python devsimpy.py

For macOS users:

$ pythonw devsimpy.py  # Required due to wxPython dependencies

Alternative Installation Methods

• Conda Environment: Use the conda_devsimpy_env.yml file.
• Portable Version: Use Portable Python with PyScripter.
• Virtual Machine: Download a preconfigured XUbuntu 19.10 VM with DEVSimPy here (Login: devsimpy-user/devsimpy).

Command-Line Usage

Execute DEVSimPy models without the GUI:

$ python devsimpy-nogui.py test.dsp -sim 10 -kernel pdevs

For PyDEVS kernel:

$ python devsimpy-nogui.py test.dsp -kernel PyDEVS 10

Check CLI options:

$ python devsimpy-nogui.py -h
