Moddy is a discrete event simulator for concept analysis written in python.

System models are written in python. The model behaviour can be event based, sequentially or a combination of both.

Moddy generates sequence diagram with timing information, model structure graphs, finite state machine graphs and trace tables from the simulation.

Typical applications are:

• Modelling communication protocols
• Modelling highly distributed computer systems

Please read the Moddy Online Documentation <https://klauspopp.github.io/Moddy>_.

Moddy comes with an interactive viewer for sequence diagrams where you can dynamically adjust the time scale. Here is a screenshot of Moddy Interactive Viewer,
better see Online Viewer Demo <https://klauspopp.github.io/Moddy/_static/2_sergw.html>_.
