ID:253010 Quartus Prime Settings File contains an illegal device <name> -- using default device instead

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

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