Abstract
A logic circuit verification device comprising a data input section to read the circuit data and the circuit information of the logic circuits to be verified and converts them into the intermediate format, a corresponding point detection section to extract and output the information about the corresponding points using the corresponding point detection algorithm, a circuit partitioning section to read the intermediate format data and partition the logic circuits according to the corresponding point information obtained by the corresponding point detection section so as to prepare circuit data of the subcircuits and a equivalence checking section to read the circuit data of the subcircuits, determine the subcircuits to be compared with referring to the corresponding point information obtained by the corresponding point detection section and comparatively compares the circuit data of the subcircuits.
