Abstract

In an integrated circuit including an array of substantially similar tiles, a tile includes a logic block and at least one column of routing multiplexers driving interconnect lines that can be used to programmably interconnect the logic blocks. An output terminal of the logic block drives a vertically adjacent subset of the routing multiplexers in the column. Optionally, the tile also includes a second column of routing multiplexers. The logic block output terminal also drives a vertically adjacent subset of the routing multiplexers in the second column, and in some embodiments the two subsets are physically located in horizontal alignment with one another within the tile. The tile can also include a column of input multiplexers for the logic block. The logic block output terminal also drives a vertically adjacent subset of the input multiplexers, and the subsets of routing multiplexers and input multiplexers can be horizontally aligned within the tile.
