Abstract
A bus macro for use as a routing resource for partial reconfiguration of a field programmable gate array (FPGA) with a design that has interdesign routing with at least one other design programmed into the FPGA comprises: at least one row of bus lines disposed within the FPGA between at least two design areas; a first set of gates disposed within the FPGA for controlling a routing of signals over the at least one row of bus lines from a first design area to a second design area of the FPGA according to a first routing configuration embedded in the first design area; and a second set of gates disposed within the FPGA for controlling a routing of signals over the at least one row of bus lines from the second design area to the first design area of the FPGA according to a second routing configuration embedded in the second design area. A method of partially reconfiguring a field programmable gate array (FPGA) with at least one design that has interdesign routing with at least one other design programmed into the FPGA is also disclosed utilizing at least one bus macro.
