This is a design where the device was filled with counters that could be selectively enabled. Several versions of the designs were tested with different counter widths. You can see from the straight lines that extrapolation of the design would have been sufficient to predict a larger design.
So, yes, you can extrapolate your data. If you would like to be conservative in your power estimates, you can create a similar design to that used to test the DE0-nano - since the counters used in that design have the worst-case toggle rates (a 1-bit counter toggles on every clock).

Ok, so if I implement 20 times my initial design which consumes 240mW, I should have a power consumption of 20*240mW? It seems to be a lot but it's what I guess after your de0_nano_power.pdf scheme...
Or is it only the core dynamic power consumption which needs to be multiplied by 20?
Thanks for helping!
