Why are my AXI-Lite register accesses to the PTP packet parser of the Ethernet Subsystem IP failing in 10G Asynchronous Clocking Mode?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 23.1, AXI-lite register accesses to the PTP packet parser of the Ethernet Subsystem IP will fail in 10G Asynchronous Clocking Mode if the AXI-ST data path clock is slower than the AXI-Lite clock.

Resolution

To work around this problem, ensure that the AXI-Lite clock is slower than the AXI-ST data path clock. 
This problem is fixed beginning with the Quartus® Prime Pro Edition software version 24.1.
