No output from FFT IP

Hi Chee,

The clock looks like that because I am using the same clock to sample with in signal tap. I've added a new clk at 2x the FFT clock speed to use with signal tap which shows the fft clock to be running as expected.

I've modified the design to us an NCO IP generating the source signal and so that it constantly runs regardless of any lack of output. I've attached the archive of this project to the reply below. I would really appreciate it if you could take a look at it for me. I've even tried using a different PC and installing a different version of quartus, but still get the same problem. I also get the same problem (no output, source valid never gets asserted) when I try using it in buffered burst mode.

Any help with this is very much appreciated.

Many thanks

Jack
