ABSTRACT:
Waveforms are acquired from a DUT into segments corresponding respectively to vectors of a vector pattern repetitively applied to the DUT. The waveform segments are displayed relative to vector numbers of the pattern to facilitate comparison of stimulus/response, debug, and other tasks. The relationship of the vector pattern is known relative to a trigger occurring once per repetition of the pattern, and vectors of the pattern are synchronous with a vector clock. The relationship of the time-domain waveform to the trigger is known. Taking account of these relationships and of system delays, each acquired waveform segment can be associated as it is acquired with a start-of-vector mark and with the corresponding vector number. Waveform displays are prepared which show the waveform segments corresponding to vector numbers of a user-selected range of vectors.
