ALLOW_REGISTER_DUPLICATION
Controls whether the Compiler is allowed to duplicate registers to improve design performance. When register duplication is allowed, the Compiler may perform optimizations that create a second copy of a register and move a portion of its fan-out to this new node, in order to improve routability and/or reduce the total routing wire required to route a net with many fan-outs.\r\n\r\nIf register duplication is disabled, optimizations that retime registers will also be disabled.\r\n\r\nThis setting affects Analysis & Synthesis and the Fitter.
