Abstract
In a field programmable gate array, a plurality of wire segments extend parallel to each other between two logic cells. Some of the wire segments extend to logic cell inputs and others to logic cell outputs. A power wire extends perpendicular to the wire segments and crosses each of the wire segments. Antifuses are disposed to couple the input wire segments to the power wire but no antifuses are disposed between the output wire segments and the power wire.
