3. Parameter Settings

The Intel® Stratix® 10 10GBASE-KR parameter editor provides the parameters you can set to configure the Intel® Stratix® 10 10GBASE-KR PHY IP core and simulation and hardware design example. You can select the Intel® Stratix® 10 10GBASE-KR PHY IP core from the Intel® Quartus® Prime Pro Edition IP catalog. To customize the PHY IP core, specify the parameters in the IP parameter editor.
Figure 5. IP Parameter Editor

The Intel® Stratix® 10 10GBASE-KR PHY parameter editor has an IP tab and an Example Design tab. For information about the Example Design, refer to the Design Example section.

Parameter Options Description
General Options
Target Stratix-10 transceiver tile L-Tile, H-Tile Specifies the transceiver tile on your target Intel® Stratix® 10 device. The Device setting of the Intel® Quartus® Prime Pro Edition project in which you generate the IP core determines the transceiver tile type.

In the current version of the Intel® Quartus® Prime Pro Edition, this parameter is grayed out. The correct tile is derived when you select a device for the project. The IP generates the correct transceiver tile type for your target Intel® Stratix® 10 device.

VCCR_GXB and VCCT_GXB supply voltage for the transceiver 1_0V, 1_1V Selects the VCCR_GXB and VCCT_GXB supply voltage for the transceiver.

For 10 Gbps data rate, you can select this value either to 1 V or 1.1 V.

Enable M20K block ECC protection On/Off When you turn on this parameter, you enable error correction code (ECC) support on the embedded Nios® II CPU system.
Enable tx_divclk port On/Off When you turn on this parameter, the tx_pma_div_clkout port is enabled. Refer to the Clock and Reset Interfaces section for more information about this port.
Enable rx_divclk port On/Off When you turn on this parameter, the rx_pma_div_clkout port is enabled. Refer to the Clock and Reset Signals section for more information about this port.
Enable tx_clkout port On/Off When you turn on this parameter, the tx_clkout port is enabled. Refer to the Clock and Reset Signals section for more information about this port.
Enable rx_clkout port On/Off When you turn on this parameter, the rx_clkout port is enabled. Refer to the Clock and Reset Signals section for more information about this port.
Enable Hard PRBS support and Native PHY Debug Master Endpoint support On/Off When you turn on this parameter, you enable the Native PHY Debug Master Endpoint (NPDME) and Hard PRBS data generation and checking logic in the Native PHY. The transceiver toolkit (TTK) requires NPDME to be enabled in the Native PHY IP core.
Enable JTAG to Avalon Master Bridge On/Off If turned on, the IP core includes a JTAG to Avalon-MM Master bridge connecting internally to status and reconfiguration registers. This allows to run the Ethernet Link Inspector using the System Console
Tab: 10GBASE-R
Reference clock frequency 644.53125 MHz

322.265625 MHz

Specifies the input reference clock frequency.
Enable additional control and status ports On/Off When you turn on this parameter, the core includes the rx_block_lock and rx_hi_ber output.
FEC Options
Include FEC sublayer On/Off When you turn on this parameter, the core includes logic to support hard Clause 74 FEC.
Set FEC_ability bit on power up and reset On/Off When you turn on this parameter, the core sets the Assert KR FEC Ability bit (0xB0[16]) FEC ability bit during power up and reset, causing the core to assert the FEC ability. This option is required for FEC functionality.

This parameter is available if you turn on Include FEC sublayer.

Set FEC_Enable bit on power up and reset On/Off When you turn on this parameter, the IP core sets the KR FEC Request bit (0xB0[18]) during power up and reset, causing the core to request the FEC ability during auto-negotiation. This option is required for FEC functionality.

This parameter is available if you turn on Include FEC sublayer.

Tab: Speed Detection
Avalon-MM clock frequency 156.25 MHz Specifies the clock frequency for mgmt_clk. The legal range is 100 MHz to 161 MHz (inclusive).

This parameter is available if you turn on either Enable Auto-Negotiation or Enable Link Training

Link fail inhibit time for 10Gb Ethernet 504 ms Specifies the time before link_status is set to FAIL or OK. A link fails if the link_fail_inhibit_time has expired before link_status is set to OK. The Ethernet standard range is 500 ms to 510 ms and IP core legal range is 10 ms to 1270 ms. For more information, refer to Clause 73 Auto Negotiation for Backplane Ethernet in IEEE Std 802.3-2015.

This parameter is available if you turn on either Enable Auto-Negotiation or Enable Link Training

Enable PCS-Mode port On/Off Enables or disables the PCS-Mode port.
Tab: Auto-Negotiation
Enable Auto-Negotiation On/Off When you turn on this parameter, the IP core includes logic to implement auto-negotiation feature.
Pause ability-C0 On/Off When you turn on this parameter, the IP core indicates on the Ethernet link that it supports symmetric pauses. For more information, refer to IEEE 802.3 Annex 28B.

This parameter is available if you turn on Enable Auto-Negotiation.

Pause ability-C1 On/Off When you turn on this parameter, the IP core indicates on the Ethernet link that it supports asymmetric pauses. For more information, refer to IEEE 802.3 Annex 28B.

This parameter is available if you turn on Enable Auto-Negotiation.

Tab: Link Training
Enable Link Training On/Off Enables or disables the Link Training feature.
Maximum bit error count 15, 31, 63, 127, 255, 511, 1023 Specifies the number of bit errors for the error counter expected during each step of the link training. The number of errors depends upon the amount of time for each step and the quality of the physical link media.

The default value is 511.

This parameter is available if you turn on Enable Link Training.

Number of frames to send before sending actual data 127, 255 Specifies the number of additional training frames the local link partner delivers to ensure that the link partner can correctly detect the local receiver state. This number is the value of wait_timer.

The default value is 127.

This parameter is available if you turn on Enable Link Training.

PMA parameters

(only available when you turn on Enable Link Training)

VMAXRULE 0-31 Specifies the maximum VOD. The default value is 30.
VMINRULE 0-31 Specifies the minimum VOD. The default value is 6.
