Why do I see stability problems with the JESD204C design examples which use the F-Tile JESD204C FPGA IP in external loopback?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 22.3, the JESD204C design examples which use the F-Tile JESD204C FPGA IP in external loopback may experience stability problems.

Depending on the exact variant you are using, these problems might manifest themselves as emb_unlock_err, sh_unlock_err, rx_gb_underflow_err, cmd_par_err, invalid_eoemb, invalid_eomb, invalid_sync_header and lane_deskew_err events.
