How to calculate power consumed by FPGA?

[Sandeep Karkera]

Hello All,

Is there any manual way to calculate the power consumed by a FPGA.
There is a tool called Xpower for Xilinx FPGAs, I just interested to know how exactly it works...

Best regards

Re: Power Calculation

Type in google for "CLB power consumption". You will find a wealth of information on the topic. The power depends on the frequency you run your design and also how many logic elements you use in the CLB.

Thank u very much
I got a good piece of information at **broken link removed**

Re: Power Calculation

Manually doing power estimation for an FPGA is very difficult and Time-consuming. For a design using >70% of Device can be rather impossible. You need to know the frequency at which internal nodes are switching and the power factor of each node. I am attaching a Xilinx Document which might help u to understand how the tool does it.

Is Spatran 3L is the lowest power FPGA or Is there any other SRAM based FPGA which is the lowest of Power consumption ?
