Title: Innovations of John A. Waicukauski

Introduction

John A. Waicukauski is a notable inventor based in Hopewell Junction, NY (US). He has made significant contributions to the field of integrated circuits, holding a total of five patents. His work focuses on enhancing the testing and reliability of very large scale integrated circuit devices.

Latest Patents

One of his latest patents is titled "Hybrid pattern self-testing of integrated circuits." This invention employs a hybrid random pattern self-test approach in an on-chip fashion to provide desired test signals to circuits on the chip. A simplified weighting circuit is shown to be effective even when only a single bit from a linear feedback shift register is employed for random signal generation. The reduction in linear feedback shift register size and associated weighting circuitry enables the apparatus to be much more readily usable in an on-product configuration, resulting in significant initial and subsequent test circuit advantages.

Another significant patent is "Weighted random pattern testing apparatus and method." This invention provides a method and apparatus for testing very large scale integrated circuit devices, particularly Level Sensitive Scan Design (LSSD) devices. It applies differently configured sequences of pseudo-random patterns in parallel to each of the input terminals of the device under test. The output responses from each of the output terminals are collected in parallel, combined to obtain a signature, and compared with a known good signature obtained by computer simulation. The input test stimuli are further altered in a predetermined fashion based on the structure of the device to be tested, allowing for individual weighting of the inputs.
