How to test a PCIe end point design?
For testing the PCIe Endpoint design plug the board into a PCIe x16 slot of a PC mainboard and connect the additional power supply socket. Boot the PC, which will not recognize the PCIe device yet, because the time needed to configure the FPGA according to the SD-Card images is too long for the BIOS to discover the device.
What is the vendor ID for a PCIe endpoint?
This PCIe Endpoint Reference design is delivered as build scripts as well as pre-built SD card images. The design implements a PCIe Endpoint with vendor ID 0x10ee and device ID 9031. It exposes multiple base address registers (BARs) to the host, each providing a separate and independent interface within the FPGA.
Can a PCI Express 2.0 motherboard be backward compatible?
Consequently, a 32-lane PCIe connector (×32) can support an aggregate throughput of up to 16 GB/s. PCIe 2.0 motherboard slots are fully backward compatible with PCIe v1.x cards. PCIe 2.0 cards are also generally backward compatible with PCIe 1.x motherboards, using the available bandwidth of PCI Express 1.1.
What’s the difference between Mini PCI and PCI Express?
PCI Express Mini Card (also known as Mini PCI Express, Mini PCIe, Mini PCI-E, mPCIe, and PEM ), based on PCI Express, is a replacement for the Mini PCI form factor. It is developed by the PCI-SIG. The host device supports both PCI Express and USB 2.0 connectivity, and each card may use either standard.
Which is standard maintained by the PCI SIG?
PCIe is a standard maintained by the PCI SIG. To proove compliance and interoperability each PCI and PCIe device needs to successfully pass a plugfest. However, due to the complexity of the technology glitches occur for specific combinations of devices. We tested the a Rev. 2 board and the provided design with the following CPUs and Mainboards:
Which is an example of a PCIe AXI bridge?
BAR0 implements a PCIe AXI bridge corresponding to an AXI-light interface. BAR1 implements a DMA channel corresponding to a pair of AXI-S interaces, which are not used in this example. BAR2 implements a PCIe AXI bridge corresponding to an AXI-MMAP interface.
