csp2B: A Practical Approach to Combining CSP and B
- 55 Downloads
This paper describes the tool csp2B, which provides a means of combining CSP-like descriptions with standard B specifications. The notation of CSP provides a convenient way of describing the order in which the operations of a B machine may occur. The function of the tool is to convert CSP-like specifications into standard machine-readable B specifications, which means that they may be animated and appropriate proof obligations may be generated. Use of csp2B means that abstract specifications and refinements may be specified purely using CSP or using a combination of CSP and B. The translation is justified in terms of an operational semantics.
