A logic verification apparatus for verifying a logic circuit includes a line recognition unit that recognizes signal lines in the circuit based on design information regarding the circuit as a starting point; a decoder recognition unit that recognizes an area including an AND gate that outputs a certain logical value and an inverter as a decoder circuit area based on the design information, and determines a logical value of an input signal inputted to the recognized decoder circuit area when a logical value of the starting point has a specific logical value; and a determination unit that determines whether a logical configuration of the recognized decoder circuit area is correct based on the number of input signals and a combination of logical values of input signals between the recognized decoder circuit areas.
