ABSTRACT:
In one embodiment of the invention, a programmable logic device (PLD) includes a plurality of programmable logic blocks arrayed in rows and columns, wherein each programmable logic block is coupled to a corresponding vertical routing resource and a corresponding horizontal routing resource, and wherein each vertical and horizontal routing resource includes a plurality of wires organized into wire groups and each programmable logic block has a set of inputs organized into input groups. The PLD also includes a plurality of connection boxes, each connection box corresponding to a programmable logic block and operable to couple a given wire group in one of the corresponding vertical and horizontal routing resources to a given input group independently of whether a given wire group in the remaining one of the corresponding vertical and horizontal routing resources is coupled through the connection box to the given input group.
