Frequent ContributorWe cant justify like that ; right way to chose the FPGA based on the EPE or Power Analyser result with premillary toggle rate.
from that static power calcualted values can be use as power dispiation when FPGA is doing nothing but powered ON.
New ContributorI guess I'm a bit confused here. If that number is wrong, what kind of number should I be seeing?
One of the parts that confuses me the most is that why am I seeing very similar number between the two cases where the FPGA is doing nothing and the case where I have a soft cpu loaded that's running an intense benchmark? I would think the doing nothing number would be much lower then the doing something number.
The only thing I can think of off the top of my head is that the intel voltage regulators don't handle the low power drain case very well. That seems to be a common issue with many switching regulators. Some of the more advanced regulators will turn off the switching and go into a linear mode in the low drain case. I do have a few snofpga boards that use a M10 with a third party linear voltage regulator. I may try one of those boards with the do nothing case.
Do you have any other thoughts that might help?
