Error: Can't generate netlist output files because the file <file name> is an OpenCore Plus time-limited file

You may see this error when compiling your design using the Quartus® II software if your design contains one or more unlicensed cores operating in OpenCore Plus mode and you have enabled an EDA simulation tool in your Quartus II project.

To avoid this error, disable the EDA simulation tool in your project by opening the Settings dialog box from the Quartus II Assignments menu. Select the category EDA Tool Settings and the subcategory Simulation. On the Simulation page of the Settings dialog box, change the Tool name option to <None>.
