DVT VHDL IDE User Guide
Rev. 19.1.34, 11 October 2019
To associate a project or remove the association of a project with DVT or CDT:
Just right-click on the project and chose Change DVT Nature. The dialog allows you to associate or remove the association with SystemVerilog, VHDL, e Language and C/C++.
The C/C++ language appears only when CDT and DVT CDT Integration features are installed.
Alternatively, C/C++ association can be achieved using:
File > New > Other and select C/C++ > Convert to a C/C++ project.
