Appendix D: Differences between Soft IP Cores and the Tri-Mode Ethernet MAC The soft PCS/PMA core: Supports the ten bit interface (TBI). Supports dynamic switching between 1000BASE-X PCS/PMA and SGMII. Outputs a status vector with bits that indicate: - The status of the link. - The status of the link synchronization state machine. - When the core is receiving /C/ ordered sets. - When the core is receiving /I/ ordered sets. - When the core is receiving invalid data. Soft PCS/PMA and Tri-Mode Ethernet MAC cores: Can be connected together to provide a single Ethernet interface. Can be configured by a vector when the management interface is not required. The vector signals equate to attributes in the hard Tri-Mode Ethernet MAC. Can be targeted to a wide variety of Xilinx® devices. 224 www.xilinx.com TEMAC User Guide UG194 (v1.10) February 14, 2011 R
