Sismic Interactive Statechart Model Interpreter and Checker

Sismic Interactive Statechart Model Interpreter and Checker

Statecharts are a well-known visual language for modeling the executable behavior of complex reactive event-based systems. The Sismic library for Python >= 3.4 provides a set of tools to define, validate, simulate, execute and debug 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

• Built-in support for expressing actions and guards using regular Python code, can be easily extended to other programming languages

• A design-by-contract approach for statecharts: contracts can be specified to express invariants, pre- and postconditions on states and transitions

• Runtime checking of behavioral properties expressed as statecharts.

• Predefined step definitions and utilities (including test coverage) to support behavior-driven development

• Synchronous and asynchronous simulation, in real time or simulated time

• Support for communication between statecharts and co-simulation

• Statechart visualization using PlantUML

Some experimental features are also available as feature branches.

Installation

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. The development occurs in the devel branch, the latest stable distributed version is in the master branch.

Sismic requires Python >=3.4

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.
