As technology gets smaller, physical effects that were Because technology features are shrinking, physical effects overlooked in the past are becoming a real problem in current circuit design. One of these effects is cross talk which represents unwanted capacitive coupling among neighboring lines. In this talk I will discuss timing analysis of sequential circuits in the presence of cross talk. First, I will review a model that can be used during the timing analysis of sequential circuits. This model conditionally captures cross talk effects. Next, I will discuss the conditions that cause coupling in both combinational and sequential circuits. Finally, I will present the results of solving the timing analysis problem in the presence of cross talk for several benchmark circuits. I illustrate analyzing coupling carefully, indeed, leads to smaller clock periods.
