The Vout pin (which is there - on the AD5681) drives the resulting analogue voltage generated by the DAC. It doesn't connect to the FPGA, only to a test point (TP1) on the board.

The five pins you list below (from the board datasheet and VHDL template) are all output signals from the FPGA. The DAC has five input signals, which these five FPGA pins drive.

So, I think you've misunderstood this aspect of the board a little.
