I work on signal processing. I try to use CIC compiler 4.0 (rev. 10) with aclken input in Vivavo 2016.1. When I run my simulation with alken holded in '1', everything works and looks good. But when I try a simulation with aclken active only every fourth rissing edge of aclk, CIC compiler output never generate m_axis_data_tvalid signal. It is no problem in simulation short time.
Any ideas what I am doing bad?
Difference of CIC input signals and respond for identical CIC is shown in picture.
