ID:18590 The imported netlist contains settings that are not supported by the current version of the software. Import using the --timing_analysis_mode option, which ignores the errors and allows Timing Analysis to be run.

CAUSE: The netlist was created using an earlier version of the Quartus Prime software, and contains settings that are not supported in the current version.

ACTION: You may be able to address the issues from the detailed legality checks, and then import again. You can also import using the --timing_analysis_mode option; this ignores certain settings from earlier versions of the Quartus Prime software that are not supported by the current version. Only use this option if you are importing the netlist to run Timing Analysis.
