Embodiments are described in which shaping is integrated with power network synthesis (PNS) for power grid (PG) alignment. Specifically, some embodiments create placement constraints based on the PG that is expected to be created by PNS, and then perform shaping (or perform legalization) on the circuit design based on the placement constraints. This ensures that the physical partitions (e.g., instances of multiply-instantiated-blocks) are aligned with the power grid during shaping.
