Why do accuracy errors occur when using the GTS Dynamic Reconfiguration Controller IP with the protocol set to “COMBO (PTP/CPRI MR)” in Quartus Prime Pro Edition software versions 25.3.1 and earlier? - Why do accuracy errors occur when using the GTS Dynamic Reconfiguration Controller IP with the protocol set to “COMBO (PTP/CPRI MR)” in Quartus Prime Pro Edition software versions 25.3.1 and earlier?
Description Due to an issue in the support logic generated for driving clock sources, accuracy errors may be observed when the COMBO (PTP/CPRI MR) protocol is selected in the GTS Dynamic Reconfiguration Controller IP when using Quartus® Prime Pro Edition software version 25.3.1 and earlier. This issue affects designs in which the COMBO protocol is configured in the GTS Dynamic Reconfiguration Controller IP for: 10GE‑1 Ethernet IP with PTP enabled, and 25GE‑1 Ethernet IP with PTP enabled. Resolution There is no workaround available for this issue in Quartus Prime Pro Edition software version 25.3.1 and earlier. This problem is resolved beginning with Quartus Prime Pro Edition software version 26.1.
