Self-checking scheme for very fast clocks' skew correction
Cecilia Metra, F. Giovanelli, M. Soma, B. Riccò · 2003
This paper presents a digital scheme to correct undesired skews between couples of clocks of synchronous systems. Correction is automatically and very fastly performed during system run-time. The proposed scheme is self-checking with respect to a wide set of possible internal (permanent as well as temporary) faults, and is easily scalable to account for different skew tolerance/sensitivity requirements. It is suitable to be implemented in VLSI, very deep submicron technology, as well as using field programmable gate arrays.
