This error is encountered when the F-Tile PMA/FEC Direct PHY FPGA IP is configured with PMA Type = FHT and Enable FHT RX data profile = Disabled. The full error signature is as follows:
Error(21843): Rule: gdrb_gdr_barak_quad::bk_en_rxdat_profile_ln0_rule @ gdr.z1577b.u_barak_quad
Error(21843): (gdr.z1577b.u_barak_quad.sup_mode -> fht_pma26g_4l_u0|directphy_f_0|dphy_hip_inst|persystem[0].perxcvr[3].fht.x_bb_f_bk.sup_mode) != SUP_MODE_USER_MODE || gdr.z1577b.u_barak_quad.powerdown_mode == TRUE || (gdr.z1577b.u_barak_quad.bk0_an_mode -> fht_pma26g_4l_u0|directphy_f_0|dphy_hip_inst|persystem[0].perxcvr[3].fht.x_bb_f_bk.an_mode) == BK0_AN_MODE_EN || gdr.z1577b.u_barak_quad.bk0_rx_line_rate < 24000000000 || (gdr.z1577b.u_barak_quad.bk_en_rxdat_profile_ln0 -> fht_pma26g_4l_u0|directphy_f_0|dphy_hip_inst|persystem[0].perxcvr[3].fht.x_bb_f_bk.bk_en_rxdat_profile) == BK0_RXDAT_PROF_EN
To resolve the problem, set the Enable FHT RX data profile = Enabled in the F-Tile PMA/FEC Direct PHY FPGA IP when PMA Type = FHT.
