Abstract

Deciding satisfiability in the theory of arrays, particularly in combination with bit-vectors, is essential for software and hardware verification. We precisely describe how the lemmas on demand approach can be applied to this decision problem. In particular, we show how our new propagation based algorithm can be generalized to the extensional theory of arrays. Our implementation achieves competitive performance.
