Abstract
Some embodiments provide a configurable IC that includes several configurable tiles. The configurable tiles include several interior tiles within the interior of an arrangement of configurable tiles. The arrangement has several sides that define the exterior boundary of the arrangement. In some embodiments, each configurable interior tile includes 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. The set of configurable input-select circuits in each interior tile has a set of inputs that are supplied by a set of asymmetric locations in the configurable IC. 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. Also, in some embodiments, each configurable interior tile includes a set of configurable logic circuits and a set of configurable routi…
