Nios II gen2 - core

Hello,

I am very new to Nios. I have a reference project folder with Nios II gen2 core used in that, and along with report files, and codes. How will I know which version of Nios core ( economy or fast) has been used in the project, without opening quartus?. I am looking for any specific string or information in report of project files that Indicates if the Nios II used is Economy or fast. Can you help?

Thanks

    Hi,

    The NIOS II system description header file, system.h contains the software definitions, name, locations, base addresses and settings for all the components in the NIOS II hardware system.


    It should be located in your <ProjectName>_bsp directory and you shall see the system.h file.

    Open it with a notepad and locate to the CPU configuration and you will see the

    #define NIOS2_CPU_IMPLEMENTATION "fast/economic"

    Thank you.


    Regards,

      Hello Kelly,

      Excuse my delayed response. I tried looking into the archive directory, but couldn't find the system.h nor the <ProjectName>_bsp directory. Any other keyword or parameters that you would recommend to look into?

      Thanks

    Hi,

    Another alternative way is locate to the Quartus you downloaded on your disk. The file path will be: Your_local_disk/intelFPGA/Quartus_version_you_installed/nios2eds/version.txt


    You should be able to see the version of the NIOS core you installed in the text file.

    Thank you.

      Hi,

      For the previous explanation, this was the <ProjectName>_bsp directory and system.h file that I mentioned as you create a file on Eclipse.

      and you should be able to see the fast/economy version using.

        Hello Kelly,

        Thanks for your swift and detailed response. I learned the project database I have is pretty old ( built with Quartus Version 13.0). The version.txt is not available either.

        Eventually just opened using old quartus version and figured out the NIOS version.
