Pthread Model Checker is a model checking tool for multithreaded programs with POSIX thread (pthread). Using it, you can detect problems which could be difficult to find by testing, such as deadlocks and livelocks.
You can write models in the programming language C (a subset). You need not study yet another modeling language.
SSG is a tool to check the correctness of programs. You can check the correctness of large-scale programs in parallel by utilizing multicore CPUs and cloud power. SSG strongly supports the development of high-quality software by detecting problems which might be overlooked with tests.

MCCSP is a CSP communication library for C/C++. Using SSG, you can implement design models checked with SyncStitch or SSG in the same CSP style consistently. This consistency can reduce the possibility to make bugs in the implementation phase. It also makes it easier to maintain source code because the correspondence and the tracability between the models and the source code are clear.
MCCSP has simple interfaces. It can easily be used for the existing systems without modifying the thread design or the class design of the systems. There is no conflict in classes of the existing code and the library as often seen in other class libraries.
MCCSP is royalty-free. The source code is bundled. You can adjust it to the target systems. For more information, please visit this page.
SyncStitch is a tool that assists software professionals to design software systems. You can describe the behavior of target systems and their components as models and check whether they behave as you expect or not. SyncStitch is based on the CSP theory (Communicating Sequential Processes).

|26 November 2016||We have formally proved one of the most important theorem in theoretical CSP "the congruence between operational semantics and denotational semantics on traces" by using the theorem prover Isabelle/HOL. We reported this achievement at the 18th society for the study of CSP held at TOYO University. You can access the outline of the proof here.|
