Abstract
Aspects of the present disclosure address improved systems and methods for core-route-based clock tree wirelength reduction. A method may include accessing an integrated circuit design comprising a clock tree comprising routes that interconnect terminals of a plurality of clock tree instances. The method further includes identifying a core route in the clock tree. The method further includes determining a first offset based on a distance between the first terminal and the core route and determining a second offset based on a distance from the second terminal to the core route. The method further includes determining a target offset based on a combination of the first and second offsets and moving the clock tree instance toward the core route by the target offset.
