ID:150016 Can't generate design file -- document is not saved or a project is not opened

CAUSE: You attempted to generate a design file from the selected block, but the Quartus Prime software cannot generate the design file because you did not save the current Block Design File (.bdf) and no project is open.

ACTION: Click OK to close the message dialog box, and then save the BDF, or create a new project and open the BDF. You may then create a design file based on the selected block.
