The PCIe® interface on the T2 card has 16 lanes and can operate in Gen 3 x16 mode or Gen 4 x8x8 bifurcated mode.

Using the PCIe Interface

  • The PCIe interface is supported with a dedicated IP block that must be instantiated in the design.
  • PCIe lane reversal is in use.
  • The server slot used with the T2 card must be a x16 capable and configured correctly for card detection and use. The Gen 4 x8x8 mode of operation requires x8 bifurcation to be enabled, whereas Gen 3 x16 requires x16 mode.
