Abstract
A method and apparatus for generating timing markers in an automatic electrical test system. Timing parameters are synchronized by an external period start signal corresponding to a centrally generated external period and an internal period start signal generated locally for each input/output pin. The timing parameters comprise T1 counter and vernier values, T2 counter and vernier values, and period-minus-T1 counter and period vernier values.
