DSP IP 6.1 - ast_sink_ready de-asserting

Seems like ast_sink_ready de-asserts by itself (for a brief moment of time initially) for pretty much all of the DSP IPs (FIR, FFT, VIPs... etc.) I dugged around and I think I found the reason for it...

Hi wronghorizon,

I'm using FFT IP version 7.0, and from my Quartus simulation it seems that sink_ready is de-asserting after some times. I've already using your FFT/IFFT Unity Gain simulink simulation for the same FFT IP core and it is working fine. Do you think I should upgrade to version 7.1 since I've read in the forum that the problem has been fixed in version 7.1?

Regards,

Shaiful
