PCI Express
The FPGA development board is designed to fit entirely into a PC motherboard with x8
or x16 PCI Express slot. Utilizing built-in transceivers on the Arria 10 GX device, it is
able to provide a fully integrated PCI Express-compliant solution for multi-lane (x1, x4,
and x8) applications. With the PCI Express hard IP block incorporated in the Arria 10
GX device, it will allow users to implement simple and fast protocol, as well as saving
logic resources for logic application.
established between the Arria 10 GX and PCI Express.
The Dual PCI Express interface supports complete PCI Express Gen1 at 2.5Gbps/lane,
Gen2 at 5.0Gbps/lane, and Gen3 at 8.0Gbps/lane protocol stack solution compliant to
PCI Express base specification 3.0 that includes PHY-MAC, Data Link, and transaction
layer circuitry embedded in PCI Express hard IP blocks.
Please note that it is a requirement that you connect the PCIe external power connector
to 4-pin 12V DC power connector in the FPGA to avoid FPGA damage due to insufficient
power. The PCIE_REFCLK_p signal is a differential input that is driven from the PC
motherboard on this board through the PCIe edge connector. A DIP switch (S1) is
connected to the PCI Express to allow different configurations to enable a x1, x4, or x8
