Automatically Generating CSP Models for Communicating Haskell Processes
Neil C. C. Brown · 2024
Tools such as FDR can check whether a CSP model of an implementation is a refinement of a given CSP specification. We present a technique for generating such CSP models of Haskell implementations that use the Communicating Haskell Processes library. Our technique avoids the need for a detailed semantics of the Haskell language, and requires only minimal program annotation. The generated CSP-M model can be checked for deadlock or refinements by FDR, allowing easy use of formal methods without the need to maintain a model of the program implementation alongside the program itself.
