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...

Dear all,

I went deeper in FFT IP tests and "global clock enable" on. In the attached screenshot a typical results is reported.

It seems that the fft module works well also by the use of clk_ena during the spectral computing phase and the data out phase, while, if I use clk_ena during the data in phase, no output is provided. Does this make sense for you?

Do you know if there is an up-date document or an errata corrige that can explain this better?

Thank a lot.
