Due to a problem in the Intel® Quartus® Prime Pro Edition Software v21.4, the F-Tile Ethernet Intel® FPGA Hard IP with FHT PMA type fails to output o_clk_rec_div (RX recovered clock) on hardware.
As the o_clk_rec_div clock is required for Advanced Timestamp Accuracy Mode, the IP cannot establish a link, and o_rx_pcs_ready will not be asserted.
To work around this problem in the Intel® Quartus® Prime Pro Edition Software v21.4, select Basic Timestamp Accuracy Mode where the o_clk_rec_div clock is not required
This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
