Summary:Examples described herein generally relate to clock tree routing in a chip stack. In an example, a multi-chip device includes a chip stack. The chip stack includes chips. The chip stack includes a clock tree. In-chip routing of the clock tree is contained within one logical chip of the chip stack. The chip stack includes leaf nodes disposed in respective chips. Each leaf node of the leaf nodes is electrically connected to the clock tree through a respective leaf-level connection bridge. The respective leaf-level connection bridge extends in an out-of-chip direction through a plurality of the chips.
