If you go to your project navigator (top right corner) of your Quartus project, right click on the name of the FPGA -> Device and pin options ->Unused pins. Does it say As tri-stated with weak pull up, otherwise your LEDs might be floating?

Hi, Thormodo!
Thanks for reply. For the Device and Pin Options settings, I have set it as tri-stated. But the unused LEDs keep blinking. May I know how to solve this problem? Any hardware coding or setting i need to do beside the device and pin options?- Mark as New

--- Quote Start --- you might just want to assign led[7:5] = 0; and all HEX(seven seg displays) values to 1 since they are active-low. --- Quote End --- Well if he's not using the LEDs, they shouldn't have a pin assignment. So he can't set them to 0. Ofcourse you can try to make these assignments and see if that works.
