Table 1. TX Path Control/Status/Statistics Signals
Name Size I/O Description
ctl_tx_send_rfi_* 1 I

Transmit Remote Fault Indication (RFI) code word. If this input is sampled as a 1, the TX path only transmits Remote Fault code words. This input should be set to 1 until the RX path is fully aligned and is ready to accept data from the link partner.

ctl_tx_send_lfi_* 1 I

Transmit Local Fault Indication (LFI) code word. Takes precedence over RFI.

ctl_tx_send_idle_* 1 I

Transmit Idle code words. If this input is sampled as a 1, the TX path only transmits Idle code words. This input should be set to 1 when the partner device is sending Remote Fault Indication (RFI) code words.

stat_tx_local_fault_* 1 O A value of 1 indicates the receive decoder state machine is in the TX_INIT state. This output is level sensitive.
stat_tx_total_bytes_* 5 O Increment for the total number of bytes transmitted.
stat_tx_total_packets_* 1 O Increment for the total number of packets transmitted.
stat_tx_total_good_bytes_* 14 O Increment for the total number of good bytes transmitted. This value is only non-zero when a packet is transmitted completely and contains no errors.
stat_tx_total_good_packets_* 1 O Increment for the total number of good packets transmitted.
stat_tx_bad_fcs_* 1 O Increment for packets greater than 64 bytes that have FCS errors.
stat_tx_packet_64_bytes_* 1 O Increment for good and bad packets transmitted that contain 64 bytes.
stat_tx_packet_65_127_bytes_* 1 O Increment for good and bad packets transmitted that contain 65 to 127 bytes.
stat_tx_packet_128_255_bytes_* 1 O Increment for good and bad packets transmitted that contain 128 to 255 bytes.
stat_tx_packet_256_511_bytes_* 1 O Increment for good and bad packets transmitted that contain 256 to 511 bytes.
stat_tx_packet_512_1023_bytes_* 1 O Increment for good and bad packets transmitted that contain 512 to 1,023 bytes.
stat_tx_packet_1024_1518_bytes_* 1 O Increment for good and bad packets transmitted that contain 1,024 to 1,518 bytes.
stat_tx_packet_1519_1522_bytes_* 1 O Increment for good and bad packets transmitted that contain 1,519 to 1,522 bytes.
stat_tx_packet_1523_1548_bytes_* 1 O Increment for good and bad packets transmitted that contain 1,523 to 1,548 bytes.
stat_tx_packet_1549_2047_bytes_* 1 O Increment for good and bad packets transmitted that contain 1,549 to 2,047 bytes.
stat_tx_packet_2048_4095_bytes_* 1 O Increment for good and bad packets transmitted that contain 2,048 to 4,095 bytes.
stat_tx_packet_4096_8191_bytes_* 1 O Increment for good and bad packets transmitted that contain 4,096 to 8,191 bytes.
stat_tx_packet_8192_9215_bytes_* 1 O Increment for good and bad packets transmitted that contain 8,192 to 9,215 bytes.
stat_tx_packet_small_* 1 O Increment for all packets that are less than 64 bytes long. Packets that are less than 64 bytes are not transmitted.
stat_tx_packet_large_* 1 O Increment for all packets that are more than 9,215 bytes long.
stat_tx_frame_error_* 1 O Increment for packets with tx_axis_tuser set to indicate an End of Packet (EOP) abort or frames aborted by de-asserting tvalid without tlast.
gig_ethernet_pcs_pma_status_vector_* 16 O See the Status Vector Table in 1G/2.5G Ethernet PCS/PMA or SGMII LogiCORE IP Product Guide (PG047).
gig_ethernet_pcs_pma_configuration_vector_* 5 O See the Configuration Vector Table in 1G/2.5G Ethernet PCS/PMA or SGMII LogiCORE IP Product Guide (PG047).
stat_core_speed_* 2 O Indicates the operating core speed:
  • 2'b10: Core configured in 10G mode
  • 2'b01: Core configured in 1G mode
  • 2'b00: Core configured in 25G mode
gpcs_resetdone_* 1 O Indicates the 1G core is out-of reset.
gt_switching_* 1 O Indicates the GT DRP operation to switch the line rate is in progress.
