Abstract

With the continuous technological advancements in digital electronic circuit technology devices are becoming even more complex, it is essential that a high level of operational reliability is maintained which is why there is always a requirement for new and improved test methodologies. A fault condition in a digital circuit may be the result of a manufacturing problem causing physical imperfection in the device, this imperfection may be open circuit or short circuit connections, or a flaw that changes other characteristics of the device. The propagation of a gate may be affected introducing a delay defect into the circuit, often creating timing problems, which have always proved difficult to detect. This paper presents a new approach to the generation of tes
