VeriODD: From YAML to SMT-LIB -- Automating Verification of Operational Design Domains

Abstract: Operational Design Domains (ODDs) define the conditions under which an Automated Driving System (ADS) is allowed to operate, while Current Operational Domains (CODs) capture the actual runtime situation. Ensuring that a COD instance lies within the ODD is a crucial step in safety assurance. Today, ODD and COD specifications are frequently expressed in YAML to remain accessible for stakeholders, but such descriptions are not directly suitable for solver-based verification. Manual translation into formal languages such as SMT-LIB is slow and error-prone. We present VeriODD, a tool that automates this translation. VeriODD uses ANTLR-based compiler technology to transform YAML-based ODD/COD specifications into both human-readable propositional logic, for lightweight review on a simple basis, and solver-ready SMT-LIB. The tool integrates with SMT solvers such as Z3 to provide automated consistency checks of ODD specifications and verification of COD conformance. A graphical user interface supports editing specifications, inspecting generated formulas, and performing verification with a single click. VeriODD thereby closes the gap between stakeholder-friendly ODD/COD notations and formal verification, enabling scalable and automated assurance of operational boundaries in autonomous driving.
