Design for testability in hardware-software systems

Clearly, in today's complex systems, hardware and software approaches to DFT must work together to achieve a successful overall solution. The authors investigate existing and new concepts that may lead to a single design for test strategy in the futur

Environmental-Based Characterization of SoC-Based Instrumentation Systems for Stratified Testing

This paper proposes a novel environmental-based method for evaluating the good yield rate (GYR) of systems-on-chip (SoC) during fabrication. Testing and yield evaluation at high confidence are two of the most critical issues for the success of SoC as a viable technology. The proposed method relies on different features of fabrication, which are quantified by the so-called Fabrication environmental parameters (EPs). EPs can be highly correlated to the yield, so they are analyzed using statistical methods to improve its accuracy and ultimately direct the test process to an efficient execution. The novel contributions of the proposed method are: 1) to establish an adequate theoretical foundation for understanding the fabrication process of SoCs together with an assurance of the yield at a high confidence level and 2) to ultimately provide a realistic approach to SoC testing with an accurate yield evaluation. Simulations are provided to demonstrate that the proposed method significantly improves the confidence interval of the estimated yield as compared with existing testing methodologies such as random testing (RT)

KHM 2006

Die KHM, die Kunsthochschule für Medien Köln, ist beinahe zwei Jahrzehnte alt. Für Akademien und Universitäten kein Alter, für eine Kunsthochschule für Medien eine lange Zeit – denn die Medien haben in diesem Zeitraum ihre Entwicklungsschritte rasant unternommen. Heute muss sich die KHM mit HD-Television, mit der Frage von bio-digitalen Lebensbedingungen beschäftigen, sie muss ihren Blick sowohl auf einen Kunstmarkt richten, der die Kunst immer ausschließlicher als Kapitalanlage begreift, sowie sich auf Medien konzentrieren, deren traditionelle Anstalten (wie beispielsweise der öffentlich-rechtliche Rundfunk) vor gravierenden Veränderungen stehen. Die digitalen Medien und ihr Einsatz in den Künsten, im Film, beim Video, in der postproduktionellen Bearbeitung, im Alltag (Kommunikation, Ökonomie und Politik) sind umfassend geworden und haben dadurch ihren Sonderstatus eingebüßt, der Zugriff auf den Computer ist Routine geworden. Für eine Kunsthochschule, deren Selbstverständnis auf den Medien (im Kunst- und Kulturkontext) beruht, sind diese Entwicklungen eine ständige und große Herausforderung. [...]The KHM, Kunsthochschule für Medien Köln – Academy of Media Arts Cologne, is almost twenty years old. For academies and universities in general, this is not very old at all, but for an academy of media arts it is a long time, for within this time span media have developed at an amazing pace. Today the KHM engages with HD television, and with bio-digital conditions of life. It confronts an art market that increasingly, almost exclusively even, views art as a capital investment, and focuses on media whose traditional institutions (for instance, public broadcasting) are on the brink of thoroughgoing changes. Digital media and their applications in the arts, film, video, post-production, and in everyday life communications, economics, and politics) have become all-pervasive and have lost their special status: access to computers is now routine. For an academy whose self-concept resides in the media (in the context of art and culture) these developments are a great and ongoing challenge. [...
