WebbProperty Directed Reachability (IC3/PDR) [4, 10] paradigm that re-lies on quantifier eliminationat word level and does not require an additional abstraction-refinement loop. It incrementally strength-ens a given safety property until it either becomes inductive, or a counterexample is found. Specifically, we built on top of the Webbmodel checking techniques, such as IC3/PDR, have gained a significant success in the hardware industry. In this paper, we present a new framework for SAT-based safety …

Webb17 apr. 2024 · Abstract. Property-directed reachability (PDR) is a SAT/SMT-based reachability algorithm that incrementally constructs inductive invariants. After it was successfully applied to hardware model checking, several adaptations to software model checking have been proposed.

WebbIn this work we propose to use Syntax-Guided Synthesis (SyGuS) for lemma generation in a word-level IC3/PDR framework for bit-vector problems. Hardware model checking is moving from bit-level to word-level problems, and it is expected that model checkers can benefit when such high-level information is available.

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. mocha countryWebb5 nov. 2024 · Both IC3 and PDR only need to store a single frame sequence, whereas IC3CFA stores one such sequence for each control location of the program.
