The Intel® Arria® 10 Avalon-ST Interface with SR-IOV PCIe Solutions User Guide explains how to use this IP core and not the PCI Express protocol. Although there is inevitable overlap between these two purposes, use this document only in conjunction with an understanding of the PCI Express Base Specification.

Note: This release provides separate user guides for the different variants.
