Hi,

I have occasionally used the powerplay with no surprises. I used the default toggle rate(I believe it was 12.5%).

How did you get power of each of muxes or fifos. If you recompile your design with just one mux then it doesn't add up because the whole FPGA is configured and functional in each case. You can't break it up like that according to my experience and version.

Your figure of few mW seems unrealistic to me (For a full stratix II I get 6W).
