This is because the MAC is normally responsible for inserting the minimum Inter-frame Gap required on the transmitted XGMII data stream, and so the receiving XAUI would never see this situation; therefore, it is up to the user to provide appropriate simulation stimulus on the XGMII interface side of the XAUI Core that meets the IEEE specification. 6. 1 Enjoy sharp imagery with realistic colors without worrying about having to adjust your living space to fit your projector display. It does timestamp at the MAC level. 4. Operating Speed and Status Signals. Adds a “hold” signal on the XGMII from the PHY to the MAC – MAC stops transmission for one clock cycle – The MAC inserts “nulls” into the data stream!

The XGMII design in the 10-Gig MAC is available from CORE Generator. Simulating Intel® FPGA IP. Serial Gigabit Media Independent Interface. 19. 6. In any case, the base concept is still the same - I don't think that your SFP module understands that it's communicating with a USXGMII core on the MAC side, which is why it's failing to complete AN and failing to get a link established. In the transmit direction, the 10GBASE-X PCS accepts packets from the PCS client on the XGMII. The design in CORE Generator contains necessary updates for Virtex-II and later devices. Marvells expertise in microprocessor architecture and digital signal processing, drives. IEEE 802. If the packet transmission was in progress at the time, the remote fault bytes will override the packet bytes until The xgmii_tx_control bit corresponds to the xgmii_tx_data bits.
