Gen3 x1, x2, x4, x8 -3, -2, -2L, -2G, -2I
  1. -1L(0.95V), -1LV(0.90V), -2L(0.85V), -2LV(0.72V).
  2. AMD UltraScale+™ devices with high bandwidth memory (HBM) contain both PCIE4 and PCIE4C blocks. Only the PCIE4C blocks support Gen3 x16 in the -2LV speed grade.
  3. -1H and -1HV are available only for Virtex UltraScale devices. -1L and -1LV are available only for Kintex UltraScale devices.
  4. The Core Clock Frequency option must be set to 250 MHz for -1, -1LV, -1L, -1H and -1HV speed grades. The Core Clock Frequency option set to 500 MHz is supported for -3 and -2 speed grades only.
  5. For Gen4 mode restrictions, see the UltraScale+ Devices Integrated Block for PCI Express LogiCORE IP Product Guide (PG213).
  6. Gen3 x8 supports normal latency (NL) and low latency (LL) mode, where core clock is 250 MHz and 500 MHz respectively. -1L and -1LV speed grades only support NL mode.
Note: Subject to the documented product features and minimum device requirements, this IP supports UltraScale+ devices with one or more PCIE4 / PCIE4C / PCIE4CE integrated blocks for PCIe. Based on available programmable logic resources, the following are not supported even if this IP is supported by the device architecture:
  • AMD Artix™ UltraScale+ FPGA devices AU15P and smaller in Gen4x8 link configuration with DMA (only AXI Bridge is supported in this link configuration).
  • Contact AMD Support for information about implementing this IP in devices containing at least one integrated block for PCIe but are not supported based on available programmable logic resources.
