Components and Interfaces
This section describes the development board's communication ports and interface
cards relative to the Arria II GX device. The development board supports the
following communication ports:
■ PCI Express
■ 10/100/1000 Ethernet
■ HSMC
PCI Express
The Arria II GX FPGA development board, 6G Edition is designed to fit entirely into a
PC motherboard with a ×8 PCI Express slot that can accommodate a full height long
form factor add-in card. This interface uses the Arria II GX device's PCI Express hard
IP block, saving logic resources for the user logic application.
f
For more information on using the PCI Express hard IP block, refer to the PCI Express
Compiler User Guide .
The PCI Express interface supports auto-negotiating channel width from ×1 to ×4 to
×8 as well as the connection speed of Gen1 at 2.5 Gbps/lane for a maximum of
20 Gbps full-duplex.
The power for the board can be sourced entirely from the PCI Express edge connector
when installed into a PC motherboard. Although the board can also be powered by a
laptop power supply for use on a lab bench, it is not recommended to power from
both supplies at the same time. Ideal diode power sharing devices have been
designed into this board to prevent damages or back-current from one supply to the
other.
