<P>PROBLEM TO BE SOLVED: To provide a programmable logic circuit device capable of improving area efficiency by removing redundancy of a logic circuit and to provide a circuit deciding method of the device. <P>SOLUTION: In the programmable logic circuit, a gate circuit realizing one logic function with a circuit change by structure data and exchange of wiring by a wiring switch portion is made common to a gate circuit realizing only the one logic function and other logic functions belonging to an NPN equivalence or the like. The circuit change is performed by giving the structure data to an input inversion portion by a programmable NOT gate for an N-operation, a fundamental circuit where a two input NAND gate or a two input OR gate is a tree structure of a binary tree and is connected by installing the programmable NOT gate between respective connection lines, and an output inversion portion by the programmable NOT gate for the N-operation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
