o The top-level SDC must correctly define the clocks reaching the input clock ports of the sub-blocks.

If a sub-block generates clocks that are used by other blocks or the top level, these generated clocks must also be properly defined (e.g., using create_generated_clock sourced from a sub-block’s output pin).
