When working in Non-Project Mode, use the following commands to open and close the Vivado IDE on the active design in memory:
start_guiopens the Vivado IDE with the active design in memory.
stop_guicloses the Vivado IDE and returns to the Vivado Design Suite Tcl shell.
stop_guiTcl command rather than the exit command.
After each stage of the design process, you can open the Vivado IDE to analyze and operate on the current design in memory (shown in the following figure). In Non-Project Mode, some of the project features are not available in the Vivado IDE, such as the Flow Navigator, Project Summary, source file access and management, and runs. However, many of the analysis and constraint modification features are available in the Tools menu.
