ON REGULAR SEGMENTED 2-D FPGA ROUTING

In this paper we analyze the properties of regular segmentation scheme s for 2-D Field Programmable Gate Arrays (FPGAs). Such schemes can be viewed as generalization of the Xilinx-like wire segmentations. We dis cuss their routing properties and propose a new FPGA design concept of applying architectural coupling to improve chip routability. We give the experimental routing results of such architectures for justificati on.
