This paper presents a digital circuit generation tool (BenCGen) that can be used to generate 24 very popular types of circuits with parameterized size. More than 1,000,000 different designs may be produced using this tool, ranging from the smallest to the largest size of each circuit. The main goal of BenCGen (BENchmark Circuits GENeration tool) is to(More)
This paper presents a new implication tool (Vimplic) which can be used to improve SAT-based combinational equivalence checking. This tool quickly builds the implication graph of the miter circuit and traverse through it inferring implications among its nodes assignments. This set of implications and the miter circuit netlist are converted to conjunctive(More)
The state-of-the-art SAT solvers, such as Chaff [11], zChaff [18], BerkMin [5], and Minisat [2] usually share the same core techniques, for instance: the watched literals structures conflict clause recording and non-chronological backtracking. Nevertheless, they generally differ in the elimination of learnt clauses as well as in the decision heuristic. This(More)
