With all the Configurations defined, move to the final screen to manage the Configuration Runs associated with them. Just like the Configurations themselves, Vivado can automatically create a set of Configuration Runs. The first Configuration in the list are defined as the parent, and all remaining Configurations are set as children to that parent.
This structure assumes that the first configuration is the most critical or challenging. Users are free to change the parent-child relationship by setting that value in the Parent column. A Parent of a synthesis run (synth_1 here) indicates the Configuration (most notably the static part) will be implemented from the synthesized netlist, and a Parent of an implementation run (impl_1 here) indicates the parent's locked static implementation result will be used as the starting point.
As you explore place and route options, timing closure techniques, and otherwise elaborate on the DFX design, multiple independent parent runs can be used for exploration. Multiple parent runs can be launched in parallel, then child runs can be launched after parent runs complete. Vivado project management handles all the DFX-specific details for creating and storing intermediate checkpoints, including a "static-only" checkpoint for a routed parent run. Ultimately, a single parent run must be selected to establish a golden static implementation result on which all Configurations will be based.
Add new Configuration Runs by selecting the green + icon. When all Configuration Runs have been created, click Next. On the final screen, the number of new elements are listed. Clicking Finish will actually perform all the requested changes in the project.
In the Design Runs window, out-of-context synthesis runs are created for each RM, and all Configuration Runs are generated. Relationships between parent and child runs are shown by the levels of indentation.
In addition, the Configurations window now shows the composition details of each Configuration available in the project.
