Nios II IDE Help System
Main Tab (Run/Debug Dialog Box)
You open this tab by clicking the Main tab on the Run/Debug dialog box for Nios II
Hardware, Nios II Instruction Set Simulator (ISS), and Nios II Multiprocessor Collection
configurations.
The options available on the Main tab depend on the configuration type. The following
sections describe the options for each configuration type.
Nios II Hardware Configurations
For Nios II Hardware configurations, the Main tab contains the following settings.
Project—Specifies the source application project. The Nios II IDE associates each
run/debug configuration with exactly one application project.
Nios II ELF Executable —Specifies which executable file (.elf) to download to the
target. This setting is read-only for Nios II C/C++ application projects and changeable
for Nios II user-makefile C/C++ application projects.
Target Hardware— Displays information related to the target hardware.
o SOPC Builder System—Displays the SOPC Builder system file that will
download to the target hardware. This value is read-only for Nios II C/C++
application projects and changeable for Nios II user-makefile C/C++
application projects.
o CPU —Displays the processor that will download to the target hardware. This
value is read-only for Nios II C/C++ application projects and changeable for
Nios II user-makefile C/C++ application projects.
o Additional nios2-download arguments—Specifies the command line
arguments to pass to nios2-download when launching. Specify the arguments
as if running nios2-download in a Nios II command shell. This option is for
advanced users only.
Note: For details on nios2-download command line arguments, type
nios2-download --help from the Nios II command shell.
o Load JDI File —Specifies which JTAG device to download the .elf file to, in
hardware designs containing multiple processors or multiple SOPC Builder
systems. Loading the JDI file ensures that the Additional nios2-download
arguments contain the correct JTAG instance ID.
Validate Nios II system ID before software download—This option is only
enabled if there is a system ID component in your SOPC Builder system. When on, the
Nios II IDE verifies the system ID in the target before downloading code. If the ID
expected by your executable does not match the actual hardware ID, a mismatch
error appears in the Console view.
Nios II Multiprocessor Collection Configurations
For Nios II Multiprocessor Collection configurations, the Main tab contains the following
settings.
Select Nios II Hardware configurations to run concurrently—Specifies multiple
run/debug configurations
to launch simultaneously.
