The Dini Group DNV7F1A User Manual You can also read back the voltages on these pins, the FPGA temperature, and the VCCINT and VCCAUX voltages using IMPACT and the JTAG chain, or by instantiating the XADC block in your design. See Xilinx 7 Series FPGAs XADC User Guide (UG480) for details on using XADC functionality within your design. 3.29 LED REFERENCE LIST There are a lot of LEDs on the board. This list describes them. In general, you can search for the text in the “Meaning” column, or for the reference designator, in the schematic to gain more knowledge about what makes them turn on and off. REF. DES.
