1. A universal reconfigurable circuit board comprising: a plurality of arbitrarily arranged sockets; a fixed interconnection network having fixed local buses directly coupling adjacent and non-adjacent pairs of said plurality of arbitrarily arranged sockets and a fixed global bus coupling to all of said plurality of arbitrarily arranged sockets; and a fixed interface circuit separate from said plurality of arbitrarily arranged sockets, said interface circuit coupled to said fixed global bus for providing interface to external circuitry, wherein, said plurality of arbitrarily arranged sockets and said fixed interconnection network are adapted to enable said plurality of arbitrarily arranged sockets to receive any one of a field programmable device, a field programmable interconnect device, and a selective shorting circuit, and wherein, logical reconfigurability of the board is achieved by reprogramming said field programmable device or field programmable interconnect device via said fixed interface circuit, and without making any physical changes to the board.
