Patent ID: 7259587

Claim:
A configurable IC comprising: a) a plurality of configurable tiles, said configurable tiles including a plurality of interior tiles within the interior of an arrangement of configurable tiles, said arrangement having a plurality of sides that define the exterior boundary of the arrangement; b) each configurable interior tile including a set of configurable logic circuits, a set of configurable input-select circuits for selecting inputs to the configurable logic circuits, and a set of configurable routing interconnect circuits for routing signals between the configurable logic circuits; c) the set of configurable input-select circuits in each interior tile having a set of inputs that are supplied by a set of asymmetric locations in the configurable IC; and d) any distance between any input-select circuit in any interior tile and any boundary-defining side of the tile arrangement is greater than any distance between any particular input-select circuit in any interior tile and any circuit that provides an input to the particular input-select circuit.
