Altera Quartus II Settings File - Manual (Page 729)

ROUTER_REGISTER_DUPLICATION
Allows the Fitter to automatically duplicate registers within a LAB containing empty logic cells. This
option does not alter the functionality of the design. The Auto Register Duplication option is also ignored
if you select OFF as the setting for the Logic Cell Insertion -- Logic Duplication logic option. Turning on
this option can allow the Logic Cell Insertion -- Logic Duplication logic option to improve a design's
routability, but can make formal verification of a design more difficult.
