Abstract
Disclosed herein are circuits in which a plurality of clock signals are generated by corresponding clock generators from one or more common clock references. The clock generators accept control values that specify the phases of the individual clocks. The actual phase of each clock signal potentially varies during operation, and the phases of the various clock signal are generally independent of each other. To detect or measure phase relationships, the disclosed circuits evaluate or compare the control values using arithmetic logic.
