Abstract:
An integrated circuit (â€œICâ€ ) device comprising:a first routing array (â€œRAâ€ ), the first RA having a configurable multiplexer, the configurable multiplexer having at least two outputs, and one output circuit, wherein one output of the configurable multiplexer of the first RA is coupled with the output circuit of the first RA; a second RA, having at least one configurable multiplexer and one output circuit, coupled to the first RA, wherein at least one output of the configurable multiplexer of the first RA is programmed to couple to the output circuit of the second RA; and a logic block, having a configurable element, coupled to the first and second RAs, wherein the configurable multiplexer of the first RA routes a signal to the logic block via the output circuit of the second RA.
