Power drawn by clock tree

[electronics20]

Hi all
How to calculate power drawn by clock tree, for instance, in a D flip-flop by HSPICE simulator?
Many Thanks

Standard IC families hhas standard FAN INs and FAN OUTs, look up the chips , see what the fan in of the clock input is, count them up, then calculate the power from the definitions of the IC family what the power is.

I need the instruction in HSPICE for a D flip-flop?
Thanks

What's the instruction to measure clock tree power in a flip-flop? Or, what's the approach to measure it? (By HSPICE 2012)
Thanks in advence
