Abstract:

Abstract: We study two dissimilar techniques, one online and one offline, for improving boolean formula assessment in two formal verification domains, circuit verification and risk assessment. We establish, despite their differences, that the key advantages of these two techniques come from formula rewriting, regardless of whether it is online or offline. We formalize a unified framework for describing these two techniques, and shown how this provides a better understanding of the interaction between different improvements to boolean formulas. Experimental support for these claims is also shown. Topic Area: correctness preserving transformations; BDD- and FSMbased approaches
