Use Modes
This section describes the standalone and in-system (or “plug-in”) use modes for the
development board. In both modes, you must provide power to the board through the
dedicated power connectors using an external power supply.
Standalone Mode
In this mode, the development board is placed on a bench, with control and data signals
coming from the surrounding interfaces, which may include the Atmel microcontroller, DIP
switches, SMAs etc. This mode is shown in Figure 3.
Figure 3: Standalone Use Mode
In-system (Plug-in) Mode
The development board is inserted into a PCIe Gen3 x8 slot of a PC. In addition to the
capabilities highlighted in the standalone mode, you may provide data traffic over the PCIe
interface in this mode, assuming you configure the PCIe interface of the FPGA appropriately.
This mode is shown in Figure 4.
Note: You will still need to provide power using an external power supply, rather than the PCIe
connector, and the dedicated power connectors on the board. Additional connectors on the PC power
supply will be sufficient.
