2.2.3. Hard IP Placement Rules

  • 400G hard IP can access both FGT and FHT PMAs, but only one at a time.
  • 200G hard IP can only access FGT PMAs (FGT3_Quad1-FGT0_Quad0).
  • PCIe* hard IP can only access FGT PMAs (FGT3_Quad3-FGT0_Quad0).
  • FGT Quad0 can only support 20-32 Gbps PAM4.
  • If IEEE 1588 precision time protocol is enabled, EMIB_6 and EMIB_7 are used, so EMIB_6 and EMIB_7 are not available for 200G hard IP.
