Critical Issue

Description

In CPRI IP core variations that target an Arria V GT device and that run at a CPRI line rate of 9.8 Gbps, the transceiver status output signals gxb_rx_pll_locked and gxb_rx_freqlocked signals are always held low.

Resolution

This issue has no workaround. Ensure you do not rely on these two status flags in these CPRI IP core variations.

This issue is fixed in version 13.1 of the CPRI MegaCore function.
