Abstract: Methods and apparatuses for clock signal phase measurement and control are described. In one example, a clock signal phase measurement system includes a reference clock signal line to provide a reference clock signal, a delay line to provide an output clock signal, and a wild clock. The clock signal phase measurement system includes a phase sensor configured to randomly and simultaneously sample the reference clock signal and the output clock signal utilizing the wild clock to obtain a phase data. The phase sensor is further configured to measure from the phase data a phase difference between the reference clock signal and the output clock signal.
