We investigate the complexity of problems on Ordered Functional Decision Diagrams (OFDDs) related to satisfiability, i.e. SAT-ONE, SAT-ALL, and SAT-COUNT. We prove that SAT-ALL has a running time linear in the product of the number of satisfying assignments and the size of the given OFDD. Counting the satisfying assignments in an OFDD is proved to be #P-complete, and thus not possible in polynomial time unless P=NP.
