PURPOSE:To simplify a gate and to reduce the number of elements by transforming a transfer switch to a general primitive such as an AND or an OR. CONSTITUTION:A file 101 including logical connecting information is compiled 201, thereafter, the N-MOS type or the P-MOS type wired connecting part circuit of the transfer switch is extracted by a part circuit extracting processing 202 to form file 102 and store the connecting information except it in a file 103. The N-MOS type or the P-MOS type wired connecting information of the transfer switch in the file 102 is transformed to an AND-OR logic according to the general primitive transforming processing A1. Thereby, a logical operation is correctly executed, the number of the elements is reduced and the simplifying processing of the circuit can be applied. |
