Webb11 jan. 2024 · We integrate the heuristics into the opensource model checker SimpleCAR and compare the performance to the original CAR and IC3/PDR on 748 instances from the hardware model-checking competitions. Our results show that by fixing the time and memory resources, CAR can solve 124 more instances with the four proposed … WebbHoare-query model, which is general enough to capture algorithms such as IC3/PDR and its variants. An algorithm in this model learns about the system’s reachable states by querying the validity of Hoare triples. We show that in general an algorithm in the Hoare-query model requires an exponential number of queries.

WebbPDR/IC3. PDR/IC3 is an invariant inference algorithm first developed for finite state model checking [3] and later extended to various classes of infinite-state systems. We describe PDR/IC3 as in [17]. PDR/IC3 maintains frames Fi as conjunctions of formulas (lemmas) representing overapproximationsof the states
