ARM Cortex-A9 power consumption

Hi All! 

 

I'm in the beginning phases of designing a board around the Cyclone V HPS and I can't find the power requirements for the on-chip A9. I've used the early power estimator for the FPGA side.  

 

Any answers or pointers would be greatly appreciated. 

 

Thanks!

You can use the power play tool if you compile for a Cyclone V HPS. I don't think the numbers are very accurate though. 

You can twiddle the switching rate of the processor in power play and it doesn't look like the dynamic power scales correctly.

By that you mean the early power estimator, right? There are no fields for the processor in that tool as far as I can see (only LUT %, IO, XCVR, etc). Are there in the version that you use?
