In the Flow Navigator, you can right-click Synthesis or Implementation, and use the following popup menu commands to reset runs. For more information, see this link in the Vivado Design Suite User Guide: Implementation (UG904).
- Reset Runs resets the run to its original state and optionally deletes generated files from the run directory.
- Reset to Previous Step resets the run to the listed step.
Tip: To stop an in-process run, click the Cancel button in the upper right corner of the Vivado IDE.
