GT – PCIe max Link Speed

Device – PCIe Max Link Speed

Shared GT_COMMON

GTX

Kintex7, Virtex7 (485T) – PCIe Gen2

PCIe Pipe Wrappers instantiate GT_COMMON. Shared IP uses QPLL because PCIe uses CPLL inside GT_CHANNEL

GTP

Artix7 – PCIe Gen2

GTP_COMMON has 2 QPLLs. PCIe Pipe Wrappers use only one QPLL. The remaining one can be used by shared IP core.
