Hi ,i recently buy a DE0-nano dev.kit and when i where dowloading a .sof with NIOS2 this happens to me. a warning say:

Info: SRAM Object File C:/Users/Juan Pablo/Documents/Facultad/Proyecto/Logica/myFirstNios2Proyect/myFirstNios2Proyect_time_limited.sof contains time-limited megafunction that supports OpenCore Plus feature -- Vendor: 0x6AF7, Product: 0x00A2

    Basically what this says is the .sof was compiled with the unlicensed trial version of NIOS and will time out.

    I don't know what the timeout period for the NIOS processor is, but it's usually pretty generous between 15 minutes and 1 hour depending on the core.

    This allows you enough time to try the core for free, but would be unacceptable for a production unit.

    To produce a continuously running NIOS system, you need the NIOS add-on license which usually runs $500 or so.

    You can re-download it any time it expires.. There's no concept of increasing "non-run" time.

    As long as you keep the kit connected and don't click on the "cancel" button from the opencore time limited alert, the design will run. If you click on "cancel" (or is it called "stop" in more recent versions of Quartus?) it will stop working immediately.

    If the JTAG connection is severed by any other mean, the design will work for about one hour.

    As anakha said, re-uploading the design will reset all those counters.
