Re: [casper] 32 parallel inputs to fft_wideband_real

[Jack Hickish]

Hi Homin,

For what it's worth, I can successfully run "update diagram" on a 32 input
2^10 point fft_wideband_real block (with mlib_devel b6e70b660) using all
default block parameters. Xilinx 14.7, Matlab 2012b.

Cheers,
Jack

Hi Jack:

I tried 128, 512, 1024, 2048 channels.
When the input is 32, the fft block generates 4 stages of butterfly, it
fails in generation of coeff_gen which is inside the 4th stage of
butterfly. There is no line connections inside the coeff_gen blocks.

Hi Homin,

What total size of FFT are you trying to do? How does the FFT fail?

Cheers,
