LED D1 is connected to the DONE pin. The DONE pin is powered by the VCCAUX supply.
The FPGA actively drives the DONE pin Low during configuration. Thus, LED D1 is unconditionally turned off during configuration.
To have LED D1 turned on or off after successful configuration, please see paragraph 11 Recommended Design Tools Settings.
