Refer to Another Project from a TriCore Project

To tell a TriCore project that another project (a TriCore single-core project, MCS project, 8051 project, ARC project or MIL library project) should be part of it, you need to create a project reference:

In the C/C++ Projects view, right-click on the name of a TriCore project and select Properties.
The Properties dialog appears.
In the left pane, select Project References.
In the right pane, select the project that must be part of the TriCore project and click Apply and Close.
