Abstract
Some embodiments provide a configurable integrated circuit (“IC”) that includes several configurable tiles arranged in a tile arrangement. Each configurable tile has a set of configurable logic circuits and a set of configurable routing circuits for routing signals between configurable logic circuits. In some embodiments, at least a first logic circuit of a first tile has at least one direct connection with a second circuit of a second tile that does not neighbor the first tile and that is not aligned horizontally or vertically with the first tile in the tile arrangement. Also, in some embodiments, each particular tile further has a set of configurable input-select circuits for receiving inputs and configurably supplying a sub-set of the received inputs to the configurable logic circuits in the particular tile. At least a first input select circuit of a first tile has at least one direct connection with a second circuit of a second tile that does not neighbor the first tile and that is not aligned horizontally or vertically with the first tile in the tile arrangement, where the direction connection is for supplying a signal to the first input select circuit. In some embodiments, several logic circuits of the first tile have at least one direct connection with at least one circuit of another tile that does not neighbor the first tile and that is not aligned horizontally or vertically with the first tile in the tile arrangement. In some embodiments, several input select circuits of the first tile have at least one direct connection with at least one circuit of another tile that does not neighbor the first tile and that is not aligned horizontally or vertically with the first tile in the tile arrangement.
