Abstract
To produce a logic circuit with excellent characteristics including area, delay time and power consumption by combining pass transistor logic circuits and CMOS logic circuits, a binary decision diagram is created from a Boolean function. Respective nodes are mapped into 2-input, 1-output, 1-control input pass transistor selectors to synthesize a pass transistor logic circuit. A pass transistor selector operating as a NAND or NOR logic with any one of its two inputs, excluding the control input, being fixed to a logical constant '1' or '0' is replaced with a CMOS gate operating as a NAND or NOR logic logically equivalent to the pass transistor selector if the value of a predetermined circuit characteristic obtained by the replacement is closer to an optimal value.
