Abstract

Embodiments of the present disclosure provide methods, systems, and computer program products for implementing retargeting-aware metal fill optimization for an IC layout. A disclosed embodiment enables a metal fill optimization design tool to identify empty space adjacent to the active metal shapes of one or more signal path nets in a metal shapes infrastructure and provide retargeting-aware metal fill insertion into empty space configured to specifically avoid foundry retargeting operations having adverse impacts on timing characteristics of signal path nets.
