The Versal™ Adaptive SoC PHY for PCI Express® IP Core internally does not instantiate the GTYP transceiver like the UltraScale or UltraScale+ PHY for PCIe IP. GT Quads in Versal premium adaptive SoC are always external to the PHY IP and they can also connect to the PHY IP. GT Quads are highly configurable and tightly integrated with the programmable logic resources.
The Versal™ Adaptive SoC PHY for PCI Express® core by default is
configured to work with AMD
PCIe MAC using phy_use_xilinx_mac
attribute set to true. Setting phy_use_xilinx_mac
to true, bypasses TX equalization and RX equalization
modules as these are present in the AMD
PCIe MAC wrapper. For using this core with a third
party MAC IP, you need to set phy_use_xilinx_mac
attribute set to false. Setting phy_use_xilinx_mac
to
false, includes TX equalization and RX equalization modules in the PHY wrapper.
