摘要: Ordered binary decision diagrams (OBDDs) are efficient representations of Boolean functions and have been widely used in various computer-aided design tools. Since the size an OBDD depends on variable ordering, it is important to find a good order for manipulation OBDDs. In particular, same multiple functions, since handled at time most The paper describes new ordering algorithms output circuits. use interleaving, while conventional appending. For some benchmark circuits, OBDDs successfully generated by using algorithms, they not algorithms. Consequently, effective allow us apply OBDD-based CAD tools wider classes
