Robustness of Nanometer CMOS Designs: Signal Integrity, Variability and Reliability
摘要
With shrinking feature sizes and increased chip sizes, the average delay of a logic gate is now dominated by the interconnection (metal wires) rather than by the transistor itself. Most of the potential electrical problems, such as cross talk, critical timing, substrate bounce, clock skew, etc., are related to the signal propagation and/or high (peak) currents through these metal wires.
