Altera FFT simulation

I'm working with Altera streaming 256 point FFT core. I've discovered the errata on the core (V9) rearding mismatch between the Matlab sims and HDL sims and the limit on the input range. Looki...

Hi all,

I am using FFT megafunction too for my final year project. The problem i had face is i can't get the output of last FFT block since it's size(eg 7 points) is not same with the previous FFT blocks size (eg 8 points). I had follow the instruction Dynamically changing the FFT Size in the manual but still can't get the output of the last FFT block. Anyone face this problem before or any idea to solve it?

Here my waveform attached. I had refer to the Figure 3-8 (Dynamically Changing the FFT Size) of FFT megafunction.
