Refinement Calculus of Reactive Systems

RCRS (the Refinement Calculus of Reactive Systems) is a compositional reasoning framework:


Implementation and download


Our group is developing a publicly available implementation of RCRS. The distribution currently includes: The tool chain is illustrated below. The tools currently allow to perform compatibility checks on a model, to simplify the entire hierarchical model into a single, monolithic symbolic transition system, and to generate simulation code in Python. See our SPIN 2016 paper for details.


To install, download the distribution (zip file) and read the README file. The Simulink2Isabelle is written in Python and relies on the third-party component:
