Hi

Any body used FFT core given by coregenerator in Xilinx ?

Does it work as they said in their data sheet..

It works very well, it is efficient, and has lots of nice features.
As for any macro, I would recommend making some (RTL) simulations
to ascertain how it must be initialized and used.

except that it is quite inefficient when it comes to calculation time

It works.  You get what you pay for, though.  There are other cores 
available that are faster and denser, but alas, they are not free.

Hi

Do you have any test project for FFT core validation ?

could you pls share it if possible.

am facing some problem in using xilinx fft core. as the output produced does not match with matlab output regards bijoy
