I'm hoping to build a broadband FFT spectrometer using the ZCU111. I need an FFT that will run at 250 MHz, and has 16 SSR paths.
I loaded the example 1D SSR FFT in Vitis_Examples/dsp/ and synthesized it. The result was that a 4x SSR FFT will run (more or less) at 250 MHz, but when I change the width to 16 SSR, then the speed drops to 80 MHz.
Is this the best that I can hope for?
Is the System Generator SSR FFT capable of 16 SSR at 250 MHz?

Thanks for your reply. I figured that out and switched to the System Generator FFT. This brings up my next question, which I asked a few weeks ago.
Can you folks at Xilinx please work on the Vector FFT in system Generator to make it be a fully functional IP block, instead of a quick test unit with no features as found in the non-vector FFT?
