WebLogic circuits can be encoded in CNF e ciently using Tseitin transformation. Such a conversion usually causes information loss. The logic paths and gates are lost. Therefore, algorithms have been proposed that aim at reconstructing circuit structures from CNF. Using these techniques might allow to apply circuit-SAT techniques to arbitrary CNFs.
