Abstract

This paper discusses the frequency to extract RLC values from interconnects. In circuit design, frequency-independent equivalent circuit is widely used, and many design and analysis techniques based on this equivalent circuit are proposed so far. However in reality, characteristics of interconnects are frequency-dependent. Also pulse wave forms in digital circuits contain multiple frequency components. The frequency used for RLC extraction affects the accuracy of interconnect characterization, and hence careful determination of extraction frequency is critical. We propose a representative frequency for RLC extraction. Conventionally, representative frequencies are determined by input pulse. The proposed method decides the representative frequency based on the interconnect length, whereas conventional representative frequencies are determined by input pulse shape, period and patterns. We verify that the extraction at the proposed frequency provides the most accurate transition wave form against various input signals and interconnect structures in digital circuits.
