Abstract
There is provided a programmable logic device (PLD) which includes a programmable wiring, the programmable wiring comprising: a plurality of switch stations (SS), first wirings each for directly connecting some terminals among input/output terminals of said SSs to input/output terminals of adjacent programmable logic elements (PLE), and second wirings each for directly connecting some terminals among the input/output terminals of said SSs to input/output terminals of the adjacent SS. Hereby, the numbers of involved switches, through which associated signals pass, can be reduced.
