Abstract
Aspects of the present disclosure address systems and methods for shortening clock tree wirelength based on target offsets in connected routes. A method may include accessing a clock tree comprising routes that interconnect a plurality of pins. Each pin corresponds to a terminal of a clock tree instance. The method further includes identifying a first and second terminal of a clock tree instance in the clock tree. The method further includes determining a first offset based on a distance between the first terminal and a branch in a first route connected to the first terminal and determining a second offset based on a distance between the second terminal and a branch in a second route connected to the second terminal. The method further includes moving the clock tree instance from a first location to a second location based on a target offset determined by comparing the first and second offsets.
