You could also select a subdevice by its uniqe id. <code>flink_subdev* subdev = flink_get_subdevice_by_unique_id(dev, 0x23a5);</code>
 Here, the subdevice with ''unique_id = 0x23a5'' is selected. This has the advantage that this unique_id does not change even in the case where subdevices are arranged differently in a FPGA design. Here, the subdevice with ''unique_id = 0x23a5'' is selected.
