ABSTRACT:
In accordance with the present invention, a field programmable gate array includes at least one programmable function unit. The programmable function unit has first and second logic circuits, each providing an output, and first and second output drivers, each having an input. The input of each output driver is adapted to be selectively coupled to the output of either of the logic circuits. A programmable interconnection is provided to selectively couple the input of the two output drivers to the output of a selective one of the logic circuits.
