Representative frequency for interconnect R(f)L(f)C extraction

This paper discusses the frequency to extract RLC values from interconnects. The frequency used for RLC extraction affects the accuracy of interconnect characterization, and hence careful determination of extraction freqnency is crucial. We propose a representative frequency for RLC extraction based on the interconnect length. We show that the proposed method enables accurate analysis of the waveform at the far-end of intercounects. We verify that the extraction at the proposed frequency provides the m a t accurate transition waveform against various input signals and interconnect structures in digital circuits.
