I guess the best way to ensure that there is no skew is to have one big buffer, and then have lines from this driver feeding all other modules requiring clocks. What I am concerned about is the amount of heat/power dissipation that would occur due to this big driver. Won't it create a hot spot on the chip? The power supply is 3.3V, is this the reason why it works? Also, the chip is designed using 0.75um process with min. channel lengths of 0.5um. How can we have long lines running in this technology? Wouldn't the transmission line effects become prominent at this point, and therefore it makes sense to use distributed driving?? Will be glad if someone would clear these doubts. Thank You. Sashi
