EFFICIENT INTERCONNECT NETWORK FOR USE IN FPGA DEVICE HAVING VARIABLE GRAIN ARCHITECTURE
摘要
A logic array device has an array of plural interconnect resources including plural lines and plural switchbox areas, with an array of plural Variable Grain Blocks (VGB's) interspersed within the array of plural interconnect resources. The array of plural interconnect resources does not regularly include lines of single-length or shorter, and the array of plural interconnect resources does not regularly include switchbox areas that are spaced apart from one another by distances of a single-length or shorter. The single-length corresponds to a traverse of a continuous distance covering approximately one VGB.
