Nios II Options Do Not Appear in Eclipse

When Nios® II SBT for Eclipse starts, the Nios II plugins might fail to load, resulting in the following symptoms:

• The Nios II perspective is not available
• No Nios II items appear when you click New in the File menu

Eclipse can behave this way if you have installed the Nios II EDS in the same directory as a previous installation.

When the Altera® Complete Design Suite installer installs the Nios II EDS, you specify a root directory for the EDS file structure. For example, if the Nios II EDS 9.1 is installed on the Windows operating system, the root directory might be c:\altera\91\nios2eds. For simplicity, Altera documentation refers to this directory as <Nios II EDS install path>.

When the Altera Complete Design Suite installer removes the Nios II EDS, it leaves behind some files in <Nios II EDS install path>. If you reinstall the Nios II EDS in the same directory, these leftover files might cause the Nios II SBT for Eclipse to work incorrectly.

To correct this problem, perform the following steps:

1. Uninstall the Nios II EDS.
2. Delete <Nios II EDS install path>, including all subdirectories, before reinstalling the Nios II EDS. Or reinstall the Nios II EDS in a different directory.

Alternatively, install the Altera Complete Design Suite version 11.0 or later.
