No. There is no such instance. My understanding: Segment is just to separate the PCI devices to different groups. Each group of devices use the continuous BUS/IO/MMIO resource. Each group has a BASE PCIE address that can be used to access PCIE configuration in MMIO way.
So with the above understanding, even a platform which has single segment can be implemented as a multiple segments platform.
