Digit Reverse Order issue for INTEL FFT IP core

Hi,

For your information, as I tested running simple example design from Q17.0 std with bi-directional, length = 8 and fixed point, I can get the correct digit reverse order when comparing between the digit reverse and natural output test cases. Would you mind to try with dummy design + fixed point to see if can get the right index? To help us narrow down if this only occurs in floating point data format.

In the meantime, I will try to customize the example design to take in your data to see if can replicate any anomaly.

Thank you.
