【Abstract】 An improved algorithm which combines cut points technique with Van Eijk’s sequential equivalence checking algorithm is presented.The false negative problem caused by the cut technique is solved,and reasonable cut results in less time for sequential equivalence checking.The calculating engine of the proposed algorithm is SAT-Solver.Experimental results show that the proposed algorithm can double the original speed.更多还原
