Experiments in Translating CSP‖B to Handel-C

Abstract. This paper considers the issues involved in translating specifications de-scribed in the CSP‖B formal method into Handel-C. There have previously been ap-proaches to translating CSP descriptions to Handel-C, and the work presented in this paper is part of a programme of work to extend it to include the B component of a CSP‖B description. Handel-C is a suitable target language because of its capability of programming communication and state, and its compilation route to hardware. The paper presents two case studies that investigate aspects of the translation: a buffer case study, and an abstract arbiter case study. These investigations have exposed a number of issues relating to the translation of the B component, and have identified a range of options available, informing more recent work on the development of a style for CSP‖B specifications particularly appropriate to translation to Handel-C
