PROBLEM TO BE SOLVED: To provide a logic synthesizer and a logic synthesis method which can easily perform determination whether insertion of a test point is proper or not, and can attempt to shorten design period by making the number of times of logic synthesis into one time. SOLUTION: This logic synthesizer is constituted using at least following parts; a logic gate circuit generating part 1 which generates a plurality of logic gate circuits of equivalent function based on behavioral description of a resistor transfer level; a test point insertion determination part 2 which determines whether insertion of a test point is necessary or not to each of the logic gate circuits, and inserts the test point when it is determined that insertion of the test point is necessary; an area calculating part 3 which calculates an area about each of the logic gate circuits for which processing by the test point insertion determination part is finished; and a logic synthesis part 4 which performs logic synthesis selecting the logic gate circuit having the smallest area.
