To set the timer settings, use either: (1) one of the Vivado IDE timing analysis dialog boxes; or, (2) one of the Tcl commands listed in this section. These settings affect other timing-related commands run in the same Vivado IDE session, except the synthesis and implementation commands.
The timer settings are not saved as a tool preference. The default values are restored for each new session. Do not change the default values. Keeping the default values provides maximum timing analysis coverage with the most accurate delay values.
The Timer Settings tab in the Report Timing Summary dialog box is shown in the figure below.
