Adding Source Files Dialog Box

ISE

Use this dialog box to verify and edit the associated Design View for the specified source file. To access this dialog box, add a source file to the project using Project > Add Source or Project > Add Copy of Source, and select one or more source files to add.

File Name
Specifies the module name for the source file that you are adding to your project. For details about source files, see Source File Types.
The status information is also displayed for each source file that you are adding to the project. If an error occurs and the file cannot be added to the project, the reason is shown next to the source file.
Association
Specifies the Design View to which the module is associated. This setting determines which Design View the source file will appear in when you select a Design View from the Design View (“Sources for”) drop-down list in the Design panel. HDL sources can be associated with Simulation, Implementation, or All. Test bench or simulation models should be associated with Simulation only. For more information on Design Views, see Using the Design Views.
Note For simulation source files, including test benches, you must ensure that the associated Design View is set to a Simulation view. Project Navigator automatically selects the Design View association for simulation source files and test benches based on the source file name. For more information, including how to customize this automatic selection, see Test Benches.
Library
Specifies the VHDL library in which to store the source file. You can select either the default work library, or select New VHDL Library to open the New VHDL Library dialog box and create a custom library. For more information, see Working with VHDL Libraries.
