CIC interpolator gives no output when stages are a power of 2

Hi,

thanks for your update. For your information, I am able to replicate the observation when using number of stages = 4 and 8, the output stuck at 0. There is no issue when I use 3,5 and 7. I have filed a case to Engineering on this to seek for further clarification. I will update you on the progress by mid of next week or as soon as there is any valid response. Please ping me if you do not hear back from me. Thank you.
