Hi! 

I have a problem with the fft megacore function 9.0! I need to do the fft with simulink. I think to have correctly chosen inputs and outputs but it won't work! Can someone help me please? I attached the file.  

 

I used a transform length of 1024 points; data precision 12 bit and also twiddle precision 12 bit. I/O data flow in streaming. enabled "global clock enable". I need to interface this fft with in input an ADC 12 bit signed and in output with a DAC 14 bit unsigned. I want the clock at 10ns because i want a sample frequency of 100 MHz so a maximum input signal of 50 MHz.
