- 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.
