ID:292024 Can't open file <name> for output.

CAUSE: You directed the Compiler to save synthesis results for the top-level design entity as an ATOM-based netlist in a Verilog Quartus Mapping File (.vqm), and then attempted to open the file, but the Quartus Prime software cannot open the file for output. This message can occur if the file name is invalid, the directory does not exist, the file is in use by another process, available memory is insufficient to open the file, an I/O error occurred when the Quartus Prime software tried to open the file, or you do not have permission to read or write to the file.

ACTION: Click OK to close the message dialog box, and then make sure that the file has a valid file name, that you have enough disk space and memory to open the file, that the disk is not corrupted, and that you have permission to read or write to the file.
