# Installing Nios II Software Built Tools (SBT) for Eclipse in Quartus Prime starting from version 19.1

from https://www.intel.com/content/www/us/en/support/programmable/articles/000086893.html

#### Description

Nios® II SBT for Eclipse is not included starting from Intel® Quartus® Prime Pro and Standard Edition Software version 19.1 onwards.

#### **Resolution**

To install the Nios® II SBT for Eclipse, **follow **the *steps below*:

1. **Download ***CDT 8.8.1 *which is Eclipse C/C IDE for Mars.2

- [CDT 8.8.1 for Windows](https://archive.eclipse.org/technology/epp/downloads/release/mars/2/eclipse-cpp-mars-2-win32-x86_64.zip)
- [CDT 8.8.1 for Linux](https://archive.eclipse.org/technology/epp/downloads/release/mars/2/eclipse-cpp-mars-2-linux-gtk-x86_64.tar.gz)

Note: Try the mirror links if the main source link doesn't work.

2. **Extract **the *downloaded file* **into ***<Intel Quartus installation directory>/nios2eds/bin.*  You should see the <Intel Quartus installation directory>/nios2eds/bin/eclipse folder after extraction is done.

3. **Rename **the* <Intel Quartus installation directory>/nios2eds/bin/eclipse folder* to *<Intel Quartus installation directory>/nios2eds/bin/eclipse_nios2*

4. **Extract **the *<Intel Quartus installation directory>/nios2eds/bin/eclipse_nios2_plugins.zip (or tar.gz for Linux) *to *<Intel Quartus installation directory>/nios2eds/bin.* The extraction will override files in <Intel Quartus installation directory>/nios2eds/bin/eclipse_nios2. 

5. **Verify** the *extraction is done* correctly by making sure you see the *<Intel Quartus installation directory>/nios2eds/bin/eclipse_nios2/plugin_customization.ini* file

6. You can now **launch ***Nios II SBT for Eclipse* via eclipse-nios2.exe

The instructions are included in the <Intel Quartus installation directory>/nios2eds/bin/README.
