6236 - PCIe for Nexus FPGAs: What is the total amount of PCIe interfaces in CertusPro-NX-100 with different lanes?
The PCI Express Link Layer Quad for all CertusPro-NX devices has four PIPE interfaces that can be used in different number of links.
This can provide the maximum flexibility, depending on the bandwidth of the application requirements. The PCIe link layer quad lane mapping is shown below:
- ×4 : All 4 lanes are used.
- ×2 : Lane 0 and Lane 1 are used.
- ×1 : Lane 0 is used.
- ×2_×1 : Lane 0 and Lane 1 are used for ×2. Lane 3 is used for ×1.
- ×1_×1 : Lane 0 and Lane 3 are used for ×1.
