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

Hi folks, I'm trying to simulate a CIC interpolator. I noticed that when the number of stages is a power of 2 (1,2,4 or 8, since the maximum is 12), I only get zeroes as the output. Any other value ...

Hi,

For your information, I am still pending for valid response from Engineering on this. I will continue to follow up and update you on the progress early next week or as soon as there is any valid response. Sorry for keeping you waiting.

As a workaround, just wonder if you are able to use non power of 2 to avoid gating your progress?

Also, a correction to my previous post, in my replication, there is no issue when I use 3, 5 and 7. The 8 is a typo. Sorry for the inconvenience.
