R-Tile PCIe* Hard IP

R-tile is a FPGA companion tile that supports PCIe* configurations up to 5 x16 in Endpoint (EP), Root Port (RP) and Transaction Layer Packet (TLP) Bypass modes. PCIe 3.0, 4.0 and 5.0 configurations are natively supported. R-tile also supports up to 16 SerDes channels through a PHY Interface for PCIe (PIPE) 5.1.1 in SerDes Architecture mode.

R-tile serves as a companion tile for the Intel® Agilex™ I-series devices.
