Just as with the standard DFX design flow, implementation results are created in-context from the top down. If any part of the design that is considered static at any point must be updated, all results for RMs below that static must be reimplemented to ensure everything stays in sync.

For example, if there is a design change for Top, all existing results must be considered out-of-date and everything must be recompiled. Clearly AMD recommends creating modular design scripts to automate the process of rebuilding implementation results. If Top remains locked and there is an update only to module A1, all results dependent on A1 (all versions of W and X, as well as A1 itself) must be recompiled, but A2 and its lower level modules Y and Z, as well as any other versions of A, are still valid.
