2.1.5. PCIe* Hard IP

The F-tile PCIe* had IP cosists of fou PCIe* coes: oe x16 (coe_0), oe x8 (coe_1) ad two x4 (coe_2, coe_3). It cosists of a set of pot bifucatio muxes to emap the fou cotolle PHY iteface fo PCI Expess* (PIPE) lae itefaces to the shaed 16 FGT laes. coe_0 ca be cofigued to suppot x16, x8, ad x4 cofiguatios, ad coe_1 ca be cofigued to suppot x8 ad x4 cofiguatios. coe_2 ad coe_3 oly suppot oly x4 cofiguatios.
