Abstract

An apparatus and method in an event based test system for testing an electronics device under test (DUT). The apparatus includes an event memory for storing timing data and event type data of each event wherein the timing data of a current event is expressed by a delay time from an event immediately prior thereto with use of a specified number of data bits, and an additional delay time inserted in the timing data of a specified event in such a way to establish a total delay time of the current event which is longer than that can be expressed by the specified number of data bits in the event memory. The additional delay time is inserted by replicating the timing data and the event type data of the event immediately prior to the specified event.
