In version 6.0, latency and initial conditions have changed for some configurations to ensure compliance with the equation for PHASE_OUT.
The latency of DDS Compiler v6.0 is different compared to v4.0 and greater in general. The update process cannot account for this and guarantee equivalent performance.
Note: When in blocking mode (that is, TREADY handshaking is present),
the latency of the core is variable, so only the minimum possible latency can be
determined. When in non-blocking mode (no TREADY), the latency of the core is as shown
in the latency field of the Vivado IDE and is constant.
