4.3.2.5. Adding Software Package

Intel supplies several add-on software packages with the Quartus® Prime. The operating system determines which software packages are available.

These software packages are available for your application to use, and can be configured in the BSP Editor from the Software Packages tab. The Software Packages tab allows you to insert and remove software packages in your BSP, and control software package settings. The software package table at the top of this tab lists each available software package. The table allows you to select the software package version and enable or disable the software package.
