Using recirculating loops, determination of off-chip driver delays can be accomplished by measuring the period of signals in the loops. As illustrated in the figure, we want to determine the off-chip driver delay at both delay points DELAY1 and DELAY2. This is done by measuring the period of signals in different paths of the circuit. By selecting different paths, using the static control lines A, B and C, we obtain period measurements.
