Methods
There are two basic technologies used for boolean reasoning in equivalence checking programs:
- Binary decision diagrams, or BDDs: A specialized data structure designed to support reasoning about boolean functions. BDDs have become highly popular because of their efficiency and versatility.
- Conjunctive Normal Form Satisfiability: SAT solvers returns an assignment to the variables of a propositional formula that satisfies it if such an assignment exists. Almost any boolean reasoning problem can be expressed as a SAT problem.
