Abstract
Aspects of the present disclosure address systems and methods for shortening clock-tree wirelength based on target offsets in connected routes. A clock tree comprising routes that interconnect a plurality of clock-tree instances is accessed from memory. A clock-tree instance is selected for evaluation. A baseline power consumption measurement corresponding to a sub-tree of the clock-tree instance with the clock-tree instance at a first size is determined. An alternative power consumption measurement corresponding to the sub-tree of the clock-tree instance with the clock-tree instance at a second size is determined. Based on determining that the baseline power consumption measurement is less than the alternative power consumption measurement, the clock-tree instance is resized according to the second size.
