Abstract: Systems, methods, media, and other such embodiments described herein relate to generation of routing trees. One embodiment involves accessing a circuit design comprising a source, a plurality of sinks, and a skew threshold associated with the source and the plurality of sinks. An initial routing tree is generated between the source and the plurality of sinks, and then a first intermediate point is identified between the source and the plurality of sinks. The first intermediate point may be identified based on a median location of all sinks of the plurality of sinks, or other criteria. The first intermediate point is then used for an updated routing tree. In some embodiments, a process proceeds iteratively until the skew threshold is reached or a maximum wire length is exceeded.
