As discussed earlier in this section, keeping the critical path within the same hierarchical boundary is helpful in debugging and meeting timing requirements. Similarly, for functional debug (and modification) purposes, signals that are related should be kept in the same hierarchy. This allows the related signals to be probed and modified with relative ease, as signal names optimized by synthesis are easier to trace when contained in a single level of hierarchy.
