According to an apparatus for automatically generating a logic circuit, when a request specification represented by a state transition diagram is input to the apparatus, the apparatus divides the specification into an information control part and an information processing part, divides the information control part into a transition state generator and a control signal generator, and specifies the transition state generator, the control signal generator, and the information processing part, as combinations of circuits, which are realized by combinations of logic elements and wirings, and wirings connecting the circuits. Therefore, the apparatus can easily cope with a change of use of the logic circuit, a change of a library of a final product, and the like. In addition, when only the state transition diagram, which represents request functions of the logic circuit naturally and compactly and which is easily described by an operator, is input to the apparatus, a large scale logic circuit can be automatically generated, thereby significantly reducing a time for developing the circuit.
