VReq
VReq is a formal framework for capturing, modeling, and validating software and systems requirements. It provides a domain-specific language known as VReq-L that expresses requirements with precise semantics, including temporal properties, data invariants, and behavioral constraints. The framework emphasizes traceability, enabling links from requirements to designs, tests, and verification artifacts.
The VReq toolchain includes a compiler for VReq-L, a model checker, and a verifier backend that can
Typical workflows: capture stakeholder needs, formalize them in VReq-L, automatically generate verification obligations, run model checking
Origins trace to academic research in formal methods; matured into a software product in 201X from a
Critics note its learning curve and the need for domain expertise; proponents argue it improves requirement
