PROGRAMMABLE LOGIC DEVICE AND DESIGNING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To permit the reduction of the power consumption and the area of a programmable logic device consisting of programmable logical elements. SOLUTION: The programmable logic device 101 consisting of programmable logical elements is provided with a first logical element 102, and a second logical element 104 having the same logic as the first logical element 102 with the lower operating speed in the upper limit of designing compared with that of the first logical element 102.
