Standards & Specifications Compliance

  • P-Tile PCIe Hard IP successfully passed PCI-SIG Compliance testing. Results posted on the PCI-SIG integrators webpage.

PCIe* Features for P-Tile Hard IP

  • Complete protocol stack including the transaction, data link, and physical layers implemented as a Hard IP.
  • Natively supports up to 4x16 for endpoint and root port modes.
  • Port bifurcation capabilities: four x4s root port, two x8s endpoint.
  • Supports TLP bypass mode in both upstream and downstream modes.
  • Supports up to 512B maximum payload size (MPS).
  • Supports up to 4096-byte (4 KB) maximum read request size (MRRS).
  • Separate reference clock with independent spread spectrum Clocking (SRIS).
  • Separate reference clock with no spread spectrum clocking (SRNS).
  • Common reference clock architecture.
  • Support for independent PERST to handle two reset operations (x8x8 EP and x8x8 TLP Bypass UP/UP).
  • PCIe advanced error reporting (PF only).
  • Support for D0 and D3 PCIe power states.
  • Lane margining at receiver.
  • Retimers presence detection.
  • Supports autonomous Hard IP mode that allows the PCIe Hard IP to communicate with the Host before the FPGA configuration and entry into user mode are complete.
  • FPGA core configuration via PCIe link (CVP Init and CVP Update).

Multifunction and Virtualization Features
