  • METAL FILL SHAPE REMOVAL FROM SELECTED NETS
    Publication number: 20210073348
    Abstract: Methods, systems and computer program products for improved metal fill shape removal from selected nets are provided. Aspects include determining a first set and second set of timing characteristics of a first and second circuit design, respectively. The first circuit design does not include metal fill shapes around a plurality of nets, whereas the second circuit design does include metal fill shapes around a plurality of nets. Aspects also include identifying a set of candidate nets based on a comparison of the first set of timing characteristics to the second set of timing characteristics. The set of candidate nets are nets that are candidates for metal fill shape removal. Aspects include generating a third circuit design by removing one or more metal fill shapes positioned around each net of the set of candidate nets that are positioned within a radius of removal.
