Mismatch between NCD and VCD signals names in PowerPlay

Hi!

I'm starting working with PowerPlay and need to estimate power from a VCD file. Although inserting the vcd, powerplay uses the default toogle rates to the estimations.

I imagine it's because I've only added internal signals to the vcd (vcd add leon3mp/u0/*) so there is a mismatch between the name of signals and those from synthesys file. Does anyone have a suggestion to solve this?

I tried to synthetize only the u0 component but, in this case, the number of required IOs is greater than the number of pins of Cyclone III.

Thanks
