  1. Right-click on the impl_1 run and select Set Incremental Implementation.

  2. In the Incremental Implementation dialog box, select Automatically use the checkpoint from the previous run.

    This dialog box can be opened from many places inside the Vivado IDE. These include the Implementation Run Options window and the Project Summary. The same functionality can also be built into scripts via Tcl commands.

  3. To enable automatic checkpoint selection via Tcl, use the following command:
    set_property AUTO_INCREMENTAL_CHECKPOINT 1 [get_runs impl_1]
After this is done, you should see the Incremental Column in the Design Runs window update to Auto(skipped). This setting indicates that Auto mode is enabled but that Incremental Implementation has not been run.

It is possible to select your own checkpoint, which is desirable when the checkpoint must not be updated or lower thresholds for reuse are OK to use. It is your responsibility to manage the suitability of the checkpoint in this case.
