1. An integrated circuit (“
- IC”
) comprising;
a plurality of configurable tiles arranged in a tile arrangement,each configurable tile having a set of configurable logic circuits and a set of configurable routing circuits for routing signals between configurable logic circuits;
wherein at least a first routing 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; and
wherein said at least one direct connection has an intervening buffer circuit that is not an interconnect circuit.

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. At least a first routing 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.
