Claim Text:
1. A method for generating a clock signal, comprising: at a root node of a clock distribution network, receiving a first clock signal generated based on a reference clock signal; at a first leaf node of a plurality of leaf nodes of the clock distribution network, detecting a reference event associated with the reference clock signal and generating a synchronizing signal based on the detection of the reference event; passing the synchronizing signal from the first leaf node to the root node; at the root node, generating a second clock signal from the first clock signal synchronized to the synchronizing signal received at the root node, and distributing the second clock signal to the leaf nodes of the clock distribution network, the generating of the second clock signal including selecting a repeating pattern of cycles of the first clock signal, wherein the repeating pattern includes fewer than all of the cycles of the first clock signal, and at least every cycle of the first clock signal that is shifted in time by a propagation delay with respect to a rising edge of the reference clock signal or every cycle of the first clock signal that is shifted in time by a propagation delay with respect to a falling edge of the reference clock signal.
