Summary:A non-transitory computer-readable medium includes instructions that, when provided to and executed by a processor, cause the processor to receive a first placement of domain instances of an integrated circuit layout provided as a tile having a group of multiple power domain modules. The first placement of domain instances is scanned to identify instances associated with a preselected power specification. A heuristic is applied to the first placement of domain instances to form an observation area. the heuristic demarcates select instances to form the observation area. Each instance associated with the preselected power specification is identified in the observation area. A contiguous region of instances is formed from the select instances in the observation area. The first placement of domain instances in the integrated circuit layout is modified to provided revised placement for instances associated with the contiguous region of instances.
