UltraScale/UltraScale+ QDRII+ IP - XSDB reports Memory Frequency incorrectly


Version Found: v1.2 (Rev 1)

Version Resolved: See (Xilinx Answer 69038)

XSDB debug information will report a 550MHz controller speed instead of the actual operating speed of 640MHz.

XSDB frequency information is held in the two values MEMORY_FREQUENCY_0 and MEMORY_FREQUENCY_1 as well as PERIOD.


This is a known issue. The incorrectly reported frequency has no effect on the operation of the controller.
