Typically, PCI Express link-up involves the following steps:
  1. Link training
  2. BIOS enumeration and data transfer

The following sections describe the flow to debug link issues during the hardware bring-up. Intel recommends a systematic approach to diagnosing issues as illustrated in the following figure.

Additionally, you can use the F-Tile Debug Toolkit for debugging the PCIe links when using the F-Tile Avalon-ST IP for PCI Express. The F-Tile Debug Toolkit includes the following features:
  • Protocol and link status information
  • Basic and advanced debugging capabilities including register read access
