1.10.307. 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.
