Implementations described herein are directed to a device with a processor and memory having stored thereon instructions that, when executed by the processor, cause the processor to acquire an integrated circuit layout of physical cells from a database and define wirelength relationships between input/output connections and a cell count for the physical cells in multiple domains. The instructions may cause the processor to define wirelength parameters of the integrated circuit layout in each domain of the multiple domains and generate a data file for the integrated circuit layout of the physical cells based on the wirelength relationships and the wirelength parameters to guide power and performance of the integrated circuit layout of the physical cells. The instructions may cause the processor to fabricate, or contribute to the fabrication of, an integrated circuit based on the data file for the integrated circuit layout of the physical cells.
