Claim:
1. A method for controlling operation of a system that extends across at least two clock domains and that comprises a plurality of functional units in different clock domains, wherein said plurality of functional units comprises a first functional unit and a second functional unit, said method comprising: driving said first functional unit in a first clock domain with a first clock-signal, driving said second functional unit in a second clock domain with a second clock-signal, receiving said first clock-signal from a first clock-signal source, providing a phase delay with respect to said first clock-signal from a component within said first functional unit for use within said first functional unit, providing said second clock-signal by delaying said first clock-signal using a first delay line, receiving reference information indicative of said phase delay from a component within said first functional unit by interrogating said component, wherein a target time-domain offset between said first and second clock-signals is based on said phase delay, and dynamically controlling said first delay line to cause said second clock-signal to sustain a temporal offset that causes an offset between said first and second clock-signals to take a step toward said target time-domain offset, and wherein said step has a first step-size that is independent of a difference between said target time-domain offset and said offset between said first and second clock signals.
