A multi-purpose digital test core utilizing programmable logic has been introduced [1,2] to implement many of the functions of traditional automated test equipment (ATE). While previous papers have described the theory, this paper quantifies the results and presents additional applications with improved methods. The digital test core provides a substantial number of programmable I/O for testing...

The increasing growth of sub-micron technology has resulted in the difficulty of testing. Design and test engineers have left no choice but to accept new responsibilities that had been performed by group of technicians in the previous years. Design engineers who do not design systems with full testability had increased the possibility of product failures and missed market opportunities. BIST is...

This paper discusses practical issues involved in applying logic built-in self-test (BIST) to four large industrial designs. These multi-clock designs, ranging in size from 200K to 800K gates, pose significant challenges to logic BIST methodology, flow, and tools. The paper presents the process of generating a BIST-compliant core along with the logic BIST controller for at-speed testing. Compar...

True software-defined radio cellular base stations require extremely fast data converters, which can currently not be implemented in semiconductor technology. Superconductor Niobium-based delta ADCs have shown to be able to perform this task. The problem of testing these devices is a severe task, as still very little is known about possible defects in this technology. This paper shows an approa...

In this work, MIG process was utilized for the wire arc additive manufacturing of wall-shaped parts, using NiTi shape-memory alloy. High-scale specimens consisting 20 layers were deposited by Ni-rich (Ni55.56Ti wt.%) as a feedstock on substrate with identical chemical composition. One two heat-treated at temperature 430 °C 1 h. The influence such heat treatment microstructure, phase transformat...

This paper outlines some of the issues and basic philosophy that have guided my work and that of my students in the last ten years. It describes the progression of conceptual representational theories developed during that time, as well OS some of the research models built to implement those theories. The paper concludes with a discussion of my most recent work in the area of modelling memory. ...

Shearer height adjusting is a key technology for shearer automation. Considering constraints of present shearer height adjusting, this paper built grey-markovian memory cutting algorithm after analyzing traditional shearer memory cutting algorithm. We firstly constructed prediction mechanism using grey model, then determined state transition probability matrix using markovian, so as to revise f...
