You specified a user library for the project in the User Library Pathnames dialog box, which is available from the New Project wizard (File menu), but one or more files in the specified directory also exist under the same name in either the default library or another library created in the Quartus II software. If you do not change the name of the files in the directory either by allowing the Quartus II software to add the prefix "old" to them, or changing the names manually, the Compiler and Simulator will ignore the files in the specified directory when searching the libraries during compilation or simulation. The Quartus II software is asking if you want to rename the files and create the user library. |
