A project is a container for design files, and for vhdl projects is equivalent to a library and has the requirement that the name be the same as the library name. The project has a similar directory structure to the suite.
Project Creation is handled by a wizard, but must be stored directly underneath the projects folder of the suite, or linked to this location.
Adding Design files like all other file structure operations can be handled by using wizards. All files which are considered to be design files must be located under the design directory in this project.
