    U have to build the FPGA system using SOPC/QSYS , the NIOS code to interact with the FPGA will have to be done using eclipse

    for ex : to transfer data from NIOS Console to DDR.

    U will have to create a system onchipmemory-DDR controller-DMA etc using SOPC/QSYS and synthesize to get an .sof

    then ur code to sent data to the write /read to the DDR will be a .c file which you have to build using eclipse and get an .elf

    U can flash both .sof n .elf and they would do the respective work.

    Is there really a space there? It shouldn't be a valid name. Your QSYs project should be called "my_nios" and not "my nios".

    When generating a system in QSYS, a .qip file is created, that tells Quartus what should be included in the FPGA project. Check that this .qip file is part of your project, and if not, add it (Project menu, Add/Remove files in project).
