ID:13233 VHDL information: ignored user-defined design library "<name>"

CAUSE: In the Quartus Prime software, you attempted to compile a project that contains a user-defined design library that you created with the Quartus Prime software version 2.0 or earlier. However, in the Quartus Prime software version 2.1 and later, you cannot include individual VHDL Design Files (.vhd) in a project using user-defined design libraries. Instead, you must analyze, compile, and otherwise process all the VHDL Design Files in a project at one time. As a result, the Quartus Prime software ignored the user-defined design library you attempted to include in the project.

ACTION: Add all the project's VHDL Design Files to the project. If you have already added all the project's VHDL Design Files to the project, no action is required.
