Abstract: We extend the learning-based automated assume guarantee paradigm to perform compositional deadlock detection. We define Failure Automata, a generalization of finite automata that accept regular failure sets. We develop a learning algorithm LF that constructs the minimal deterministic failure automaton accepting any unknown regular failure set using a minimally adequate teacher. We show how LF can be used for compositional regular failure language containment, and deadlock detection, using non-circular and circular assume guarantee rules. We present an implementation of our techniques and encouraging experimental results on several non-trivial benchmarks.
