ABSTRACT:
The present invention aims to provide a programmable logic device (PLD), and a related control program, capable of improving a product yield by avoiding a defect point according to defect point detected after PLD fabrication.The PLD includes a plurality of logical blocks including programmable logic circuits; storage in which both circuit information specifying path connecting the plurality of logical blocks using information specifying resources included in the path and defect point information specifying fault resource are stored in advance; replacement control section which refers to defect point information, decides whether fault resource is included in the path specified by circuit information, and when fault path is included, obtains replacement path, and rewrites circuit information with data identifying resources included in replacement path; and wiring resource section which reads out circuit information stored in storage, and forms a predetermined logic circuit based on readout circuit information.
