It is interesting,

Sorry for interrupting, do you mean that I cannot find the debug level in the new GUI? I am not sure but you still can use the shell commands.

Correct?

    Dear ABola2,

    Let us first of all determine what the debug level means.

    In my questions debug level is about hardware part of the project, which I can choose in Qsys/Platform Designer

    I just use "level" because of the Nios II classic form of choice (pic.1). Btw sorry for 5 levels, there are actually four,

    I just included the absent of debug as level.

    Pic.1 Nios II classic JTAG Debug settings

    As for the Nios II gen2 I just can turn JTAG Debug on and choose what

    functions of Debug I need. For example, I can turn on the Onchip Trace (pic.2)

    Pic.2 Nios II gen 2 JTAG Debug settings

    So I turn this on, and then... I'm not sure if there is any instrument

    for the new Quartus which support Tracing mode, or even profiling mode
