ALLOW_REGISTER_RETIMING

Controls whether the Compiler is allowed to retime registers to improve design performance. When register retiming is allowed, the Compiler may perform optimizations that move combinational logic across register boundaries, maintaining the overall logic of the design component but also balancing the data path delays between each register.\r\n\r\nThis setting affects the Fitter.
