The Synthesis Settings enable you to specify the constraints set, the synthesis strategy, the synthesis options, and what reports to generate. The options are defined by the selected synthesis strategy or synthesis reporting strategy, but you can override these with your own settings. You can select an option to see a description at the bottom of the dialog box. For more information on the Synthesis Settings, see the Using Simulation Settings section in the Vivado Design Suite User Guide: Synthesis (UG901).
Note: You can pre-synthesize IP in your project, which decreases the synthesis runtime. For information on using this bottom-up synthesis flow, see the Vivado Design Suite User Guide: Designing with IP (UG896).
Tip: You can add Tcl scripts to be sourced before and after synthesis using the tcl.pre and tcl.post files. For more information, see the Vivado Design Suite User Guide: Using Tcl Scripting (UG894).
