14 years agoIt is a window that is opened if the Quartus programmer uploaded a time limited .sof (which happens when you compiled a design with cores you don't have the license for). It says something like "opencore plus evaluation" and prevents you from using the programmer further. You need to keep this window open, or else all the licensed components (including the Nios II CPU) cease to work.
