2.4.1.2.4. Adapting to SGMII

You can use the GMII-to-SGMII Adapter core to adapt the GMII HPS EMAC PHY signals to an Serial Gigabit Media Independent Interface (SGMII) PHY interface at the FPGA transceiver I/O pins using logic in the FPGA and the multi gigabit transceiver I/O or LVDS SERDES in soft CDR mode. While it is possible to design custom logic for this adaptation, this section describes using Platform Designer adapter IP.

GUIDELINE: Use the GMII to SGMII Adapter IP available in Platform Designer.

Configure the HPS component in Platform Designer for an EMAC “To FPGA” I/O instance and choose GMII as the PHY interface type along with a management interface. Do not export the resulting HPS component GMII signals in Platform Designer. Instead, add the Intel GMII to SGMII Adapter IP to the Platform Designer subsystem and connect to the HPS component’s GMII signals. The GMII to SGMII Adapter IP makes use of the Intel HPS EMAC Interface Splitter IP in Platform Designer to split out the “emac” conduit from the HPS component for use by the GMII to SGMII Adapter. The adapter IP instantiates the Intel Triple Speed Ethernet (TSE) MAC IP, configured in 1000BASE-X/SGMII PCS PHY-only mode (that is, no soft MAC component). For more information about how to use the Intel GMII to SGMII Adapter IP, refer to the Embedded Peripherals User Guide.

GUIDELINE: Since the TSE MAC IP with 1000BASE-X PCS option no longer provides an option for the transceiver I/O, to implement an SGMII PHY interface using the FPGA transceiver I/O for an Intel® Stratix® 10 HPS EMAC instance, you must select "NONE" for the PCS I/O option, which gives you a TBI interface. The transceiver PHY IP must be separately instanced and connected in Intel® Stratix® 10.
