Why is the RX Core FIFO full if PMA and PCS bonding mode is enabled in H-Tile Transceiver Native PHY Intel® Stratix® 10 FPGA IP?

Description

Due to a problem with Quartus® Prime Pro Edition Software version 17.1, the H-Tile Transceiver Native PHY Intel® Stratix® 10 FPGA IP may output incorrect rx_clkout frequency if the PMA and PCS bonding mode is enabled for non-PCIe mode. The incorrect rx_clkout frequency will cause the RX Core FIFO to become full.

Resolution

Use PMA-only bonding for non-PCIe mode. This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 18.1.
