When I say its "working" in simulation, I mean that through LabView I
generated a FM modulated signal sampled at 50MSPS (same as my system)
and used that as the input test vector to my design.
I am doing functional verification using ModelSim and I can see that
I*I + Q*Q outputs being computed, but they don't seem to be present in
hardware.
I am thinking there is something weird going on system wise that is
leading to this anomaly, maybo some harmonics that are leading to
cancellations or something, because I just cannot understand why the
I*I multipliers are not working

Chipscope?
