Abstract
A repeatable non-uniform segmented routing architecture in a field programmable gate array comprising: a repeatable block of routing tracks, the routing tracks grouped into sets of routing tracks, each set having a first routing track in a first track position, a second routing track in a last track position, a programmable element, and a direct address device for programming the programmable element; wherein at least one of the routing tracks is segmented into non-uniform lengths by the programmable element and the second routing track crosses-over to the first track position in a region adjacent to an edge of the repeatable block; and wherein a first plurality of the routing track sets proceed in a horizontal direction and a second plurality of the routing track sets proceed in a vertical direction.
