Abstract:
A field programmable gate array has columns of logic modules. A programming conductor used to conduct programming current to program antifuses of the field programmable gate array extends between two adjacent columns of logic modules. First wire segments extend from the programming conductor and toward the logic modules of a first of the two adjacent columns. Second wire segments extend the opposite direction from the programming conductor and toward logic modules of the second of the two adjacent columns. Programming current used to program antifuses disposed along the first wire segments as well as antifuses disposed along the second wire segments can be supplied from the same programming conductor that extends between the two columns of logic modules. The logic modules of the first column are mirrored versions of the logic modules of the second column.
