1.6.2.2. The board_spec.xml File

The board_spec.xml file contains metadata necessary to describe your hardware system to the Intel® FPGA SDK for OpenCL™ . Include the board_spec.xml file as part of your custom platform deliverable.

The information conveyed in the XML file includes device resource such as ALMs and DSP blocks available, memory component characteristics and channel information if your device supports streaming applications, and kernel interface information.

Below is an example of the board_spec.xml file for the Intel® Arria® 10 GX FPGA Development Kit Reference Platform.
