Sismic for Python
Sismic Interactive Statechart Model Interpreter and Checker
Sismic is a recursive acronym that stands for Sismic Interactive Statechart Model Interpreter and Checker.
Statecharts are a well-known visual modeling language for representing the executable behavior of complex reactive event-based systems. Sismic library for Python (version 3.10 or higher) provides a set of tools to define, validate, simulate, execute and test statecharts. More specifically, Sismic provides:
An easy way to define and to import statecharts, based on the human-friendly YAML markup language
A statechart interpreter offering a discrete, step-by-step, and fully observable simulation engine
Fully controllable simulation clock, with support for real and simulated time
Built-in support for expressing actions and guards using regular Python code, can be easily extended to other programming languages
Support for Design by Contract (DbC) for statecharts: contracts can be specified to express invariants, pre- and postconditions on states and transitions
Runtime monitoring of behavioral properties expressed as statecharts
Built-in support for behavior-driven development (BDD)
Support for communication between statecharts
Synchronous and asynchronous executions
Statechart visualization using PlantUML
Installation
Sismic requires Python >=3.10. Sismic can be installed using pip as usual: pip install sismic. This will install the latest stable version.
You can also install Sismic from this repository by cloning it.
Starting from release 1.0.0, Sismic adheres to a semantic versioning scheme.
Documentation
The documentation for the latest distributed version is available on sismic.readthedocs.io.
Many examples are available in docs/examples.
The documentation can also be directly built from the docs directory using Sphinx.
The scientific article A method for testing and validating executable statechart models presenting the method and techniques supported by Sismic for validating and testing statecharts, is published in Springer’s Software and Systems modeling journal in 2018.
Changelog
See documentation’s changelog.
Credits
The Sismic library for Python is mainly developed by Alexandre Decan at the Software Engineering Lab of the University of Mons with the help of many contributors.
Sismic is released as open source software under the GNU Lesser General Public Licence version 3.0 (LGPLv3).
