Channel and Pin Placement for the Gen1, Gen2, and Gen3 Data Rates

The following figures illustrate the x1, x2, x4, and x8 channel and pin placements for the Arria 10 Hard IP

for PCI Express.
In these figures, channels that are not used for the PCI Express protocol are available for other protocols.

Unused channels are shown in gray.
Note: In all configurations, physical channel 4 in the PCS connects to logical channel 0 in the hard IP.

You cannot change the channel placements illustrated below.

For the possible values of and , refer to the figures that show the

physical location of the Hard IP PCIe blocks in the different types of Arria 10 devices, at the start of this

chapter. For each HIP block, the transceiver block that is adjacent and extends below the HIP block, is

, and the transceiver block that is directly above is .

For example, in an Arria 10 device with 96 transceiver channels and four PCIe HIP blocks, if your design

uses the HIP block that supports CvP, is GXB1C and is GXB1D.
