Hi Xi,
The clock will indeed be printed as a period (and with the unit being Ticks).
You can set a period as low as 1 tick if you want, so with the default
resolution that would correspond to 1THz(!)

Hi Andreas,
Thanks for the clarification. So when I set --clock in the command line, the
config.ini file prints clock period, is that right? That is also explains why
you cannot set more than 1GHz in Ruby network frequency, because 1GHz is the
smallest clock period or we can treat it as base clock period, when you set
more than 1GHz, you cannot shrink base clock period anymore but expand it by
setting smaller clock frequency. Is my understanding correct?
Thanks,
Xi

Hi Xi,
The clock is a parameter of type Clock, and it is specified in terms of a clock
period in units of ticks internally. Hence, your setting as a frequency will
end up being printed as a clock period.
Hope it helps.
Andreas

Hi all,
I tried another way to adjust the frequency. Set -clock= to 0.5GHz, 0.33GHz,
0.2GHz, then in the config.ini file the corresponding clock under "system.ruby"
became 2,3,5. So the frequency adjustment does work, but the question is why
set clock to 2,3,4 GHz, the system does not change and set clock to 0.5,0.33
and 0.2 the real clock is 1/0.5=2, 1/0.33~3 and 1/0.2=5?
Sorry for bothering!
Thanks,
Xi
