ID:128009 Design has <number> percent of logic elements back-annotated -- can't perform fitter netlist optimizations when more than <number> percent of LEs are back-annotated

CAUSE: You turned on fitter netlist optimizations, however, the Quartus Prime software cannot perform fitter netlist optimizations when more than the specified number of LEs are back-annotated.

ACTION: If you want to use fitter netlist optimizations on the design, remove some location assignments. If you want to back-annotate a design after using fitter netlist optimizations, you must generate a Verilog Quartus Mapping File (.vqm) that indicates the duplicated LUTs that the Quartus Prime software generated and/or resynthesized while fitting the design, and specify a new source. Otherwise, no action is required.
