You can set several global settings that affect the entire design using the Vivado Design Suite Synthesis Settings. These settings optimize how logic is inferred and how incremental synthesis is run. Xilinx recommends using default options when you start your design and changing the options based on the specific needs of your design. For more information, see this link in the Vivado Design Suite User Guide: Synthesis (UG901).
