Programmable integrated circuit having L-shaped programming power buses that extend along sides of the integrated circuit
 A programmable integrated circuit (see FIG. 9) has a plurality of L-shaped programming power buses (for example, 126, 130, 129 and 127) that extend along sides of the integrated circuit. Each L-shaped programming power bus extends along two adjacent sides of the integrated circuit such that legs of two L-shaped programming power buses extend along each of the sides. There are four pluralities of programming drivers (for example, 110, 117, 115 and 112), one plurality being associated with each of the four sides. There are also four programming current multiplexers (for example, 118, 125, 123 and 120), one associated with each of the sides. A programming driver of one of the plurality of programming drivers is selectively couplable to one of the two L-shaped programming power bus legs that extends along the associated side of the integrated circuit via the programming current multiplexer associated with that side. Additional pluralities of programming drivers and additional programming current multiplexers can be provided.
