Creating a design from scratch is an old story now. These days, a design is usually modified from a reference or legacy design. This requires reuse of either schematic sheets, blocks, or a complete design. With global teams, different functions/blocks of the schematic design and their associated layout modules are captured by multiple teams.
No designer would like to redraw the circuit; they would rather merge the existing functional designs into the master design seamlessly. This could create a new set of challenges such as an undesired sequence of reference designators. Other than this, you might have come across many other challenges.
