ID:303004 Formal verification may give mismatches -- Perform gate-level register retiming is turned on

CAUSE: You attempted to optimize netlists during synthesis by directing the Quartus Prime software to perform gate-level register retiming, specified a formal verification tool for the current project, and compiled the design. However, formal verification may give mismatches between the pre- and post-Quartus Prime netlists if the logic feeding registers is modified in the design due to this option.

ACTION: Specify that the Quartus Prime software not perform gate-level register retiming, and recompile the design.
