    I figured out the problem, maybe it is a question too easy to be answered. the commands Nios II Eclipse send out are

    Do load_sim.tcl.

    LD

    Change the ld to ld_debug will make all signals show up.

    finally, I think I know how this Nios II Eclipse and Questa works. I would say, AN351 as a tutorial was a failure. I will give it barely grade C if it is a high school project. maybe there is good one which I don't know. maybe I should have read the "Quartus Prime Pro Edition Handbook Volume 1 ,2, 3" and "Nios® II Software Developer Handbook" line by line.

    Intel may have the best FPGA and design tools. the barrier to entry is so discourage, that is good news to who want to earn more money.

    I will read it carefully, it will take some time for a 500 page document. for a board designer, when I learn Orcad/Allegro design tools from Cadence, sometimes even very simple question, will be answered by the forum. it will be much faster and easier than to read a thousand page user manual. if there is no help, the only way you solver your problem is rely on yourself.

    Thank you for the document.
