4.13.2.1. Physical Layout of Hard IP in Arria V Devices

/>Arria V devices include one or two Hard IP for PCI Express IP cores. The following figures illustrate the placement of the PCIe IP cores, transceiver banks, and channels. Note that the bottom left IP core includes the CvP functionality. The other Hard IP blocks do not include the CvP functionality.

Transceiver channels are arranged in groups of six. For GX devices, the lowest six channels on the left side of the device are labeled GXB_L0, the next group is GXB_L1, and so on. Channels on the right side of the device are labeled GXB_R0, GXB_R1, and so on. Be sure to connect the Hard IP for PCI Express on the left side of the device to appropriate channels on the left side of the device, as specified in the Pin-out Files for Intel Devices.
