1. A method for auto-skew alignment of high-speed differential eye diagrams, said method comprising: providing a pair of time-dependent differential signals related to one another by a differential timing skew; constructing mathematical functions dependent on magnitudes of said differential signals and said differential timing skew; defining a figure of merit containing time integrals of said mathematical functions; and calculating an optimized value of said differential timing skew such that said figure of merit reaches a minimum value.
