Power Estimation

I am experimenting with different architectutal features affered by nios and I would like to estimate the power for each of the architectures... Suppose I wish to compare the power when a particular benchmark is run on two different architectures [to see if a particular architecture offers any energy-saving advantages over another]... Does neone have any idea how this can be achieved?

Thnx in advance

    check out the powerplay tool that Quartus offers, it has in-depth power analysis that you may find useful

    I did check it out... It uses the Signal Activity File that's generated by the Simulator to estimate the power. However, I'm unsure of what inputs I should provide to the simulator as the PowerPlay power analyzer report always says that the User has provided insufficient toggle rate data..

    So any ideas on how to do the simulation (and using what inputs) to provide a valid Signal activity file (SAF) to be used with PowerPlay to get High confidence Level???
