Abstract	This paper presents a new model forglobal routings in FPGAs. The irregular interconnections in FPGAs can be generalized as multiple buffered interconnect stages, of which the electrical waveform can be adequately approximated. Based on the model, expressions of delay and fundamental throughput of the interconnections have been derived and validated. They are shown in line with the SPICE and FPGA experimental results. Moreover, the model shows that interconnection throughput can be significantly increased using wave-pipelined signaling instead of the conventional delay-based synchronous approach, as has been demonstrated in our FPGA experiments. We conclude this paper by having a discussion about a strategy to further enhance the interconnect throughput.
