Nios II IDE launches quartus programmer

I have created a system on a DE3 board. When I try to run the software on it using the Nios II IDE, it finishes the project build, and then launches the quartus programmer window - the program does not run. The Nios II IDE does not show any error messages.

When I try to simulate this system using Altera ModelSim, it stops after about 700 ns with the error "ERROR: cpu1_test_bench/i_readdatavalid is 'x'". I can see it go to invalid in the wave window, but cannot figure out what is causing it.

    If the nios2 IDE cannot actually find your processor in the JTAG chain, the assumption is that you've got the wrong firmware loaded into the FPGA. It then launches the quartus II programmer so you can program your firmware into the FPGA. You should have seen a printout in the console indicating that it couldn't find your CPU. Note there are multiple consoles in the IDE and you might have a different one showing. If you click on the little drop-down arrow next to the console icon above the console window, you can select one of the other consoles.

    I only have one console open in the IDE. I am also not getting the printout in the console indicating it couldn't find my CPU (I have gotten this previously, but not anymore).

    I am however, programming my board using a .jic file - am I still able to use the IDE if I use this file type? Can I program the DE3 board with just the .sof file?

    Thanks,

    You don't exactly open multiple consoles. The IDE kind of does it on it's own. On the right hand side of the screen you'll see an icon that looks like a GUI window with a '+' sign in the upper right hand corner of the icon. Next to the icon is a drop-down arrow. Click on the arrow and it should show you the available consoles. Usually you get one for the build where the IDE prints out the compilation information and another one for the download.

    Yes, when I click on the drop down arrow, my only options are CVS or New Console View - I do not have multiple consoles open.
