Making TLA+ and x86 Kiss Via Z3Py

Read Original

This article explores translating a subset of TLA+ into Z3Py to bridge formal specifications with verification tools such as Verus, CBMC, and an assembly checker. The author discusses the TLA+ ecosystem's value for software engineering and proposes a library-based approach to validate correspondences between specs and implementations. A practical example using an hour clock specification demonstrates loading TLA+ modules, inferring sorts, and extracting transition relations as Z3 BoolRef expressions. The work is presented as a work-in-progress, with a GitHub repository link provided.
