is that not in the documentation ?

does the user guide or the associated docs help ?
at the end of the day, I guess it depends on what your doing with the board,
if your running the fpga and associated bits at full speed or is most of it in idle ?

Thanks for your replies!
SRIO contoller is impelement in the fpga, it is occupies near 35% of the die, SRIO is Gbit protocol. But I want to know the whole power consumption of SP605 board.

the tools should tell you what power is to take max,
bu tthe peripherals,
I guess your going to have to meassure the power taken by the board then,

Power consumption is design dependent. In SP605 depends upon which reference design you loaded.

In addition to XPA (in ISE GUI, its an option under PAR), Xilinx also provides another power tool called XPower Estimator (XPE), which can be found at www.xilinx.com/power. With this you don't need an actual design (you can import design data with a mrp file) and can input some estimated design parameters in order to estimate your max power. There is a process variation that you can set to max, then just max out your usage and you should have a pretty good estimate for your total max power. You can apply this to any part really if its supported in the power tools.

Given the choice between:
I will have greater confidence in the results of the tool which uses the actual design for its calculations.
If you do not have a design for analysis, then there is but one choice between the two: the estimator.

I agree completely Bob, the estimator is intended to be used when you don't have a design, which is the impression I got from the OP. With XPE though its MUCH easier to input data faster if all you want is to try and estimate maximum power for a given device.
Use XPA if you want a full accurate analysis, use XPE if you want a quick estimation w/o a design file or with (yes you loose routing info, like net capacitance, but its quick and easy to use for an estimate).
