Automatically synthesizing consistent models is a key prerequisite for many testing scenarios in autonomous driving or software tool validation where model-based systems engineering techniques are frequently used to ensure a designated coverage of critical cornercases. From a practical perspective, an inconsistent model is irrelevant as a test case (e.g. false positive), thus each synthetic model needs to simultaneously satisfy various structural and attribute well-formedness constraints. While different logic solvers or dedicated graph solvers have recently been developed, they fail to handle either structural or attribute constraints in a scalable way.
