This application discloses a computing system to implement a place and route tool to synthesize a clock tree in a layout design of an integrated circuit based on timing constraints for the integrated circuit. The computing system can select a portion of the clock tree to present in a schematic connectivity presentation based on a conformance of the portion of the clock tree to timing constraints for the clock tree. The computing system can compress the other portions of the clock tree into the compacted representation based on the selection of the portion of the clock tree. The compacted representation can retain a hierarchical connectivity of the other portions of the clock tree. The computing system can generate the schematic connectivity presentation of the clock tree that includes the selected portion of the clock tree coupled to at least one compacted representation of other portions of the clock tree.
