MOCHA: Modularity in Model Checking. MOCHA is a growing interactive software environment for system specification and verification. The main objective of MOCHA is to exploit, rather than destroy, design structure in automatic verification. MOCHA is intended as a vehicle for development of new verification algorithms and approaches. MOCHA is available in two versions, cMocha (Version 1.0.1) and jMocha (Version 2.0).
