CHP2LOTOS Translator for CHP (Communicating Hardware Processes)

Organisation: Inria Grenoble Rhône-Alpes and LIG, Grenoble (FRANCE)

Functionality: Translation from CHP (Communicating Hardware Processes) into LOTOS

Tools used: CADP (Construction and Analysis of Distributed Processes)

Period: 2005-2009

Description: CHP (Communicating Hardware Processes) is a process calculus dedicated to the description of asynchronous hardware architectures. CHP extends standard process calculi with particular synchronisation features implemented using handshake protocols.

The CHP2LOTOS tool translates a CHP description into LOTOS, enabling their verification with the CADP toolbox. The particular synchronisation features (e.g., the probe operator) are translated into dedicated processes to represent communication channels. Whenever possible, CHP2LOTOS optimises the translation avoiding channel processes. CHP2LOTOS is equipped with a generic C library to support the numerical data types of CHP.

Conclusions: The CHP2LOTOS translator provides a direct connection of the CHP language for asynchronous hardware to all the state-of-the-art verification features of the CADP toolbox. The translator was validated in several case-studies, including a router of an asynchronous network on chip.
