Capturing crosstalk-induced waveform for accurate static timing analysis

We propose a method to capture crosstalk-induced noisy waveform for crosstalk-aware static timing analysis. The effects of capacitive coupling noise on timing are conventionally measured as delay variation. On the other hand, the propose method derives an equivalent waveform to a crosstalk-induced noisy waveform. The crosstalk effects on timing are all included in the equivalent waveform. With the derived equivalent waveform, we can perform static timing analysis with consideration of dynamic delay variation due to crosstalk noise. The equivalent waveform is derived by our improved least square fitting with weighting coefficient. Our method can naturally consider the slew variation due to crosstalk noise as well as the delay variation. We experimentally verify that our method can estimate the delay variation at the output of the receiver gate accurately. The strength is that the proposed method requires no additional library characterization and is easy to be integrated into usual s...
