1.7. Channel Availability
PCIe Hard IP Channel Restrictions
Each L- or H-Tile transceiver tile contains one PCIe Hard IP block. The following table and figure show the possible PCIe Hard IP channel configurations, the number of unusable channels, and the number of channels available for other protocols.
Figure 2. PCIe Hard IP Channel Configurations Per Transceiver Tile
PCIe Hard IP Configuration | Number of Unusable Channels Remaining in the Tile | Usable Channels Remaining in the Tile |
---|---|---|
PCIe x8 | 0 | 16 |
PCIe x16 | 0 | 8 |
The table below maps all transceiver channels to the PCIe Hard IP channels in the available tiles.
Tile Channel Sequence | PCIe Hard IP Channel | Index within I/O Bank | Bottom Left Tile Bank Number | Top Left Tile Bank Number | Bottom Right Tile Bank Number | Top Right Tile Bank Number |
