Hello, Why are unused LEDs dimly lit but the rest of the FPGA is working as expected? What is the best way to ensure all unused LEDs are off? Thank you, Jeremy

The code is working fine except that LEDs [9:1] are dimly lit. I am using the free software - Quartus Prime Lite 18.1 and the ModelSim. module Mux_4_to_1 (Mux_Out, Sel, Mux_In); input [1:0] Sel;...

    Hi,

    You have to solder the JP5 2-pin header only if you are using the dual image boot function on the DE10-Lite board

    Thanks.

Hello YY,

I just looked up the example files I believe you are referring to. (https://www.intel.com/content/www/us/en/programmable/support/support-resources/design-software/quartus-ii/quartus.html) . I haven't ran any of these. The VGA demo files I have ran are in: DE10-Lite_v.2.0.3_SystemCD\Demonstrations\VGA_Pattern . The VGA file along with the others work great and no LEDs are dimly lit. However, with my projects, the LEDs that are not used are dimly lit. I'm not sure what I am missing. It seems as if the LEDs may be tied to a "weak" pull down?? I will attach one of my projects including my test bench (which simulates fine).
