Hi Chao-Te, The 100% utilization of DSP48's seems to be your problem. I would try using slices instead. In the fft and pfb paramater box, you can do this by checking 'specify multiplier use' and then entering in a vector that specifies the multipliers you want to use. I think you want 'behavioral,' so if you have a 2^7 fft, you would enter in: [2 2 2 2 2 2 2].
