Abstract:
A method of adaptively adjusting the timing offset of a digital signal relative to a clock signal output substantially coincident with the digital signal to enable a latch receiving the digital signal to store the digital signal responsive to the clock signal, the method comprising:applying the digital signal to the latch;storing the digital signal in the latch responsive to the clock signal;evaluating the stored digital signal to determine if the stored digital signal has an expected value and storing the result of this evaluation;adjusting the timing offset of the digital signal relative to the clock signal;repeating storing the digital signal in the latch through adjusting the timing offset of the digital signal for a plurality of timing offsets;selecting a final timing offset of the digital signal from the ones of the timing offsets that caused the latch to store the digital signal having the expected value; andadjusting the timing offset of the digital signal relative to the clock signal to the selected final timing offset.
