By default, the Vivado simulator saves your configuration changes to a file under the simulation's working directory as you work with the user interface controls and Tcl commands of the Vivado simulator. The settings that are saved include the following:
- The state of the filter buttons and column widths of the Scopes and Objects windows.
- Tcl properties of the simulation, including array display limit, default radix, default time unit for the run command, and trace limit.
- Radixes and the Show as Enumeration state that you set on HDL objects in the Objects window.
After you shut down the simulation, the Vivado simulator restores your settings when you reopen and run the Vivado simulator.
