Patent ID: 8643399

Claim:
A programmable logic device comprising: an array of functional blocks; input/output elements disposed at a periphery of said programmable logic device; and a plurality of conductors configured to conduct signals between said array of functional blocks and further between said array of functional blocks and said input/output elements; wherein said plurality of conductors comprise a first plurality of said conductors that are available to propagate signals in a direction away from an edge of said programmable logic device and into said array, wherein said first plurality of conductors comprise continuous conductors that originate outside said first functional block and conduct uninterrupted signals through said first functional block to a second functional block of said array; wherein said plurality of conductors further comprise a second plurality of said conductors that are available to propagate signals out of said array in a direction toward said edge of said programmable logic device, wherein said second plurality of conductors comprise continuous conductors that originate outside said first functional block and pass uninterrupted signals through said first functional block; and wherein the total number of said conductors that propagate signals out of said array is greater than the total number of said conductors that propagate signals into said array.
