Abstract

Methods and systems for performing route-based cell merging for a clock tree. The methods and systems access, from memory, a circuit design comprising a clock tree that interconnects a clock source to a plurality of clock sinks through a plurality of components. The methods and systems generate a Steiner tree that represents at least a portion of the clock tree including a portion of the plurality of components and identify two or more components of the portion of the plurality of components in the Steiner tree that are part of a direct fanout of a common node representing a set of components of the plurality of components. The methods and systems determine that the identified two or more components satisfy a mergeability function and, in response, modify at least a portion of the clock tree by merging the set of components into a single component.
