1.1. Cyclone V Avalon-ST Interface for PCIe Datasheet
Altera® Cyclone® V FPGAs include a configurable, hardened protocol stack for PCI Express® that is compliant with PCI Express Base Specification 2.1 or 3.0. The Hard IP for PCI Express using the Avalon Streaming (Avalon-ST) interface is the most flexible variant. However, this variant requires a thorough understanding of the PCIe® Protocol. The following figure shows the high-level modules and connecting interfaces for this variant.
