ID:253011 Quartus Prime Settings File contains an illegal device family <name> -- using default device family <name>

CAUSE: You selected Device in the Category list in the Settings dialog box, but the Quartus Prime software read an illegal device family from the Quartus Prime Settings File (.qsf). You may have edited the QSF manually and specified an illegal family name. The Quartus Prime software cannot compile the project using the specified device family and is switching to the specified device family.

ACTION: Click OK to close the message dialog box. If the device family chosen by the Compiler is appropriate for the design, then no action is required. Otherwise, specify a different device family. To avoid receiving this message in the future, Intel recommends using the Device page to specify a device family, rather than editing the QSF manually.
