Abstract

This paper addresses the issue of obtaining compact canonical representations of datapath circuits with sequential elements for the purpose of equivalence checking and component matching. First, the authors demonstrate the mechanisms for an efficient compositional construction of the arithmetic transform (AT), which is the underlying function representation used in modern word-level decision diagrams (WLDDs). Second, presented is a way of generating the canonical transforms of the sequential and imprecise datapath circuits
