A logic circuit module is used for designing a semiconductor integrated circuit using an FPGA (Field Programmable Gate Array) or a short-term gate array. Provided that a seventh input terminal of the logic circuit module is fixed to the power supply, a third multiplexer always selects the output of a second multiplexer, and a signal selected by the second multiplexer is directly output to a second output terminal. Moreover, an AND circuit always outputs an output signal of a first multiplexer to a first output terminal. Thus, fixing the seventh input terminal to the power supply causes respective logics formed from the first multiplexer and the second multiplexer to be separated by the third multiplexer, allowing for independent representation of the logics. Accordingly, the area efficiency of the logic circuit module is improved, resulting in reduction in size of the semiconductor integrated circuit.
