Mutual Exclusion in a Token Ring in CC++

Abstract

This report describes a first attempt at using UNITY to verify reactive Compositional C++ (CC++) programs. We propose a distributed solution to the mutual exclusion problem using partially synchronous communication channels. The solution is described as a CC++ program, from which a small set of "basic" properties is derived. Using UNITY, we proof mutual exclusion and progress of the solution based on the set of properties derived from the code.
