Nios II simulation with Questa

Dear Support, After few weeks struggle, finally I got the AN351 working on my Quartus Pro 21.3. I am so happy and feel surprised. there is still something not working as expected. most of the s...

    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.

Hi David,


First and foremost, we would like to apologies for the support experience you are having so far in the forum.


We have good news regarding the this issue, we have Nios V and it will use Questa:

Also, for your ease, you can refer below video for the step by step:

If you have any issues/questions regarding Nios V, let me know. Or you may post your questions separately.

Hi Eberlazare

Thank you very much for the reply. I guess Nios V will be much better than Nios II. I am working on an old project which was created at 2016. Quartus 16 revision, I hope I can transfer the project to Quartus 21.3 pro. Then to make improvement, I need a working platform first. is there a tutorial to migrate from Nios II to Mios V. as a beginner, to migrate a working system is easier than to create a one from scratch.

Appreciate you help.

David
