This invention provides means and methods for improving the routing and multiplexing logic of microprocessor busses and other similar high fan logic functions in FPGA and ASIC circuits. Routing of high fan-in signals is simplified by distributing the multiplexing function. The multiplexing function is separated into an AND function in the logic block and a programmable OR function in the routing block. Programming bits control which signals are ORed together in the routing elements. The AND output of a peripheral is controlled by either a distributed control circuit or by control signal(s) from a centralized control circuit.
