I am trying to use https://github.com/freecores/versatile_fft , but after I run "make all", data_out.txt and res.txt are all empty.

Anyone have same experience ?

Are you feeding it real inputs and doing anything with the outputs?

Synthesis tools are really good at figuring out what logic isn't being  
used, and trimming it.  It's pretty common to make something just to see  
if it'll synthesize and find out that it's not there because you gave it  
constant inputs or didn't bring the outputs to pins.
