iam using fft IPcore to implement on FPGA.
IP Core FFt needs 2's compliment no's as input.
for simulating i am connecting DDS o/p to FFt Input which is also IPCore.
since DDS o/p is not 2's compliment iam not able to get the fft out put correctly.
can any body tell me how can i solve this problem?
if i want write a test bench how can testbench can be written to generate 2,s compliment o/p
