Abstract
In one embodiment, the disclosed methodology and apparatus measure relative duty cycle information of a clock signal with respect to an input node as the clock signal travels to selected nodes of a clock distribution network on an electronic circuit. The apparatus operates in a benchmark mode to determine benchmark duty cycle information and then subsequently operates an a relative mode to determine relative duty cycle information of the clock signal at a selected node in comparison to the clock signal at an external input node.
