AbstractIn this paper we analyze the properties of the Xilinx-like regular segmentation schemes for 2-D Field Programmable Gate Arrays (FPGAs). We introduce a new notion of architectural level routing decaying effect caused by wiring segmentation. We discuss its routing properties and propose a relative prime number based segmentation scheme for 2-D FPGA architectures. A new FPGA design concept of applying architectural coupling to achieve better routability is also introduced and experimentally justified
