Abstract
The noise problem becomes a critical issue in the advanced technology when IR drop and crosstalk noises occur simultaneously. Traditionally, timing analysis superposes induced delays by the IR drop noise and also by the crosstalk noise. In this paper, we observe that the combined effect of both noises is much larger than the superposition of individual noise induced delays. To accurately compute the noise induced delay, we use the concept of the sliced switching window to estimate the IR drop noise and the crosstalk noise. We also propose an iterative methodology to consider the combined effect of IR drop and crosstalk noises. Our experimental results are very promising.
