Summary: 
We propose an estimation method of crosstalk noise for generic RC trees. The proposed method derives an analytic waveform of crosstalk noise in a 2-π equivalent circuit. The peak voltage is calculated from the closed-form expression. We also develop a transformation method from generic RC trees with branches into the 2-π model circuit. The proposed method can hence estimate crosstalk noise for any RC trees. Our estimation method is evaluated in a 0.13 µm technology. The peak noise of two partially-coupled interconnects is estimated with the average error of 11%. Our method transforms generic RC interconnects with branches into the 2-π model with 14% error on average.
