How to update .mif data from on chip ram????

Hi,

I have create avalon-MM slavo part for my 1 port RAM and I use .mif file as my memory file for my 1 port RAM. When I run in Nios2 IDE software, I can read all the .mif data successfully.

But, when I change the data in .mif file, and rerun again in Nios2 IDE software, I still get previous .mif data.

May I know how to update my .mif data?

thanks!!!

    You don't need to recompile the whole Quartus project.

    Simply select Update Memory Initialization File in Quartus processing menu.

    And do not forget to re-run the assembler after that.

    Basically:

    1. change .mif file(s)

    2. select Update Memory Initialization File in Quartus processing menu

    3. run the assembly step
