mdc |
Output |
MDC clock to External PHY device |
This port is replaced by mdio_phy_mdc. Connect the PHY MDC port to this port. |
mdio |
Bidirectional |
MDIO data line to External PHY device |
The core no longer instantiates the Bi-Di I/O primitive. Instead, it gives out the _i, _o, and _t signals, which should be connected to a Bi-Di I/O primitive. This primitive has to be user-instantiated. |
The following ports were added to the core (non-shared logic).

Description |
What to do |
---|---|---|---|
ref_clk_in |
Input |
200 MHz clock from the shared logic block to the core |
This should be driven by one of the following: •the shared logic provided with the core •by another cores shared logic block •from another cores shared logic block •from an external clock source |
gmii_clk_125m_in |
Input |
Present only when GMII clock is sourced internally (C_EXTERNAL_CLOCK = 0) 125 MHz GMII TX clock from the shared logic block to the core |
This should be driven either by the shared logic provided with the core, or by another cores shared logic block. |
gmii_clk_25m_in |
Input |
Present only when GMII clock is sourced internally (C_EXTERNAL_CLOCK = 0) 25 MHz GMII TX clock from the shared logic block to the core |
This should be driven either by the shared logic provided with the core, or by another cores shared logic block. |
gmii_clk_2_5m_in |
Input |
Present only when GMII clock is sourced internally (C_EXTERNAL_CLOCK = 0) 2.5 MHz GMII TX clock from the shared logic block to the core |
This should be driven either by the shared logic provided with the core, or by another cores shared logic block. |
mdio_phy_mdc |
Output |
MDC clock to External PHY device |
Connect this to External PHY device MDC input. |
mdio_phy_i |
Input |
The _o output from the Bi-Di primitive on the MDIO Data line from the External PHY Device |
Connect this to the _o port of the Bi-Di I/O primitive on the MDIO to the External PHY device. |
mdio_phy_o |
Output |
The _i input to the Bi-Di primitive on the MDIO Data line from the External PHY Device |
Connect this to the _i port of the Bi-Di I/O primitive on the MDIO to the External PHY device. |
mdio_phy_t |
Output |
The _t input to the Bi-Di primitive on the MDIO Data line form the External PHY Device |
Connect this to the _t port of the Bi-Di I/O primitive on the MDIO to the External PHY device. |
