Why Arria 10 Multi-rate Ethernet PHY USXGMII mode Auto-Negotiation doesn't work in simulation?

Environment

  • Ethernet
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    The default value of usxgmii_link_timer at register address 0x412 is 0x7c000. This default reset value sets the link timer to 1.6ms, which is too long in simulation.

    Resolution

    Set usxgmii_link_timer bit[14]=1 at address 0x412 to speed up the auto-negotiation process for simulation. This setting is equals to usxgmii_link_timer=0x4000, which is the fastest link timer value can be set in this register (0.05ms).

    For further detail description of usxgmii_link_timer, refer to Intel Arria 10 Transceiver PHY User Guide.
