Switching between versions of Nios II EDS

Are any changes needed for Q7.1?

How about Q5.0 - did it follow the same convention?

The following Altera_Tool_Switch.bat also includes an option for version 7.1. Note that this is an example, and paths for versions 6.1 and 7.0 are different from the default installation path. 7.1 and 5.0 follow the same conventions for Nios II, but version 5.0 requires additionally setting the QUARTUS_ROOTDIR, and QESS_ROOTDIR environment variables. One difference for versions 5.1 through 6.1 are that we added, then subsequently removed, an environment variable called SOPC_BUILDER_PATH_XX with the version number (XX) appended, such as SOPC_BUILDER_PATH_60. You can add an option for version 5.0 by defining SOPC_BUILDER_PATH, SOPC_KIT_NIOS2, QUARTUS_ROOTDIR, and QESS_ROOTDIR appropriately to match your installation. The last 2 should be set to the same directory, the Quartus installation directory. I think it was version 6.1 when we modified Quartus to automatically update these last 2 environment variables simply by launching the correct version of Quartus (which is what the script does now). Although I have not tried this script (modified for 5.0) with version 5.0 myself, I know of at least one customer who did so without difficulty.

Altera_Tool_Switch.bat (reference example, modify to match your selected install paths):

I am using Quartus II 9.1 and I found that set SOPC_BUILDER_PATH to be empty (or null string "")

is necessary for SOPC Builder 9.1.

Or it will get confusion for components in C:\altera\megacore\ that have same "component" names as that in C:\altera\91\ip\altera

Thank you!

I reinstall a new xp system,and using yunduan software.Altera Quartus ii can still work,but environment variable of nois ii missed and nois ii can't work.

It's you saved me,and save me time of installing of nois ii.
