Résumé : CADP is a toolbox for specifying and verifying asynchronous finite-state systems described using process algebraic languages. It offers a wide range of state-of-the-art functionalities assisting the user throughout the design process: compilation, rapid prototyping, interactive and guided simulation, verification by equivalence/preorder checking and temporal logic model-checking, and test generation. The languages, models, and verification techniques used in CADP have a broad application domain, allowing to deal with communication protocols, distributed systems, embedded software, mobile telephony, asynchronous hardware, cryptography, security, human-computer interaction, etc. CADP is currently used both in industrial companies and academic institutions for research and teaching purposes. During the last years, over 50 applications and case-studies performed using CADP have been reported.
