Abstract:
1. A routing fabric in an integrated circuit, comprising: a plurality of branches, where each branch comprises at least two consecutive levels of switching networks, a routing matrix of the plurality of leaf cells of each branch of the plurality of branches; wherein each of the switching networks of each branch and the routing matrix of the plurality of leaf cells of each branch comprises a respective first plurality of ports and a respective second plurality of ports, wherein the pins of a plurality of ports of the first plurality of ports of a first routing matrix of a first branch of the plurality of branches are connected to the pins of a plurality of the second plurality of ports of a plurality of leaf cells of the first branch; and wherein the pins of a plurality of the second plurality of ports of the first routing matrix are directly connected to the pins of the first plurality of ports of each switching network of the at least two levels of switching networks of at least two branches of the plurality of branches.
