Time-aligning communication channels

Abstract:

An example process for aligning channels in automatic test equipment (ATE) includes programming a first delay associated with receiving first data over a channel so that timing of the channel is aligned to timings of other channels in the ATE; programming a second delay associated with a driver driving second data over the channel based on receipt of an edge of the second data so that timing of the second data is aligned to the timing of the channel; and programming a third delay associated with a signal to enable the driver to drive the second data over the channel, with the third delay being programmed to align timing of the signal to the timing of the channel, and with the third delay being based on an edge that corresponds to an edge of the signal created by controlling operation of the driver.
