how to set redhawk frequency for multi clocks

hi all

In my designs, there are several clocks, such as 125M, 260M. the precondition is we have vcd file. if I set the frequency as125M, it is 0.6W, while I set freq as 256, it will double, 1.2W.

1. In the User Guide: "For example, assume that there are thre e significant frequencies on the chip, and
they consume the following power: 100 MHz (5mw), 200 MHz (20mw), and 400 Mz
(70mw). The FREQUENCY value to be specified in this case would be 200 MHz,
even though a majority of the power is consumed at 400 MHz. Required. Default:
none. "

I dont understand why "The FREQUENCY value to be specified in this case would be 200 MHz, even though a majority of the power is consumed at 400 MHz". if there are 5 clocks, 100M, 150M, 200M, 250M, 400M. which will be used?

how to set the frequency for multiple clocks?

2. another questions?
can set I as the below:
FREQ: 150M
CLOCK_ROOTS {
CLK1 100M
CLK2 150M
CLK3 200M
CLK4 250M
CLK5 400M}

Will the responding FF/combination cells to the clock domain use the corresponding frequency?

or any other suggestions?

Many thanks for your help?
