Abstract
An event based test system for testing an electronics device under test (DUT) by supplying a test signal to the DUT and evaluating an output of the DUT at a timing of a strobe signal. The event based test system includes an event memory for storing timing data of each event which represents a time difference between two adjacent events, an address sequencer for generating address data for accessing the event memory, a timing count logic for summing the timing data to produce an overall time of each event relative to a predetermined reference point, an event generation circuit for generating each event based on the overall time for formulating the test signal or strobe signals, and a host computer for controlling an overall operation of the event based test system.
