Novel Hierarchical Test Architecture for SOC Test Methodology Using IEEE Test Standards
Dongkwan Han,Yong Lee,Sungho Kang 대한전자공학회 2012 Journal of semiconductor technology and science Vol.12 No.3
Abstract?SOC test methodology in ultra deep submicron (UDSM) technology with reasonable test time and cost has begun to satisfy high quality and reliability of the product. A novel hierarchical test architecture using IEEE standard 1149.1, 1149.7 and 1500 compliant facilities is proposed for the purpose of supporting flexible test environment to ensure SOC test methodology. Each embedded core in a systemon-a-chip (SOC) is controlled by test access ports (TAP) and TAP controller of IEEE standard 1149.1 as well as tested using IEEE standard 1500. An SOC device including TAPed cores is hierarchically organized by IEEE standard 1149.7 in wafer and chip level. As a result, it is possible to select/deselect all cores embedded in an SOC flexibly and reduce test cost dramatically using star scan topology.
A New Multi-site Test for System-on-Chip Using Multi-site Star Test Architecture
Dongkwan Han,강성호 한국전자통신연구원 2014 ETRI Journal Vol.36 No.2
As the system-on-chip (SoC) design becomes morecomplex, the test costs are increasing. One of the mainobstacles of a test cost reduction is the limited number oftest channels of the ATE while the number of pins in thedesign increases. To overcome this problem, a new testarchitecture using a channel sharing compliant with IEEEStandard 1149.1 and 1500 is proposed. It can significantlyreduce the pin count for testing a SoC design. The testinput data is transmitted using a test access mechanismcomposed of only input pins. A single test data output pinis used to measure the sink values. The experimentalresults show that the proposed architecture not onlyincreases the number of sites to be tested simultaneously,but also reduces the test time. In addition, the yield lossowing to the proven contact problems can be reduced. Using the new architecture, it is possible to achieve a largetest time and cost reduction for complex SoC designs withnegligible design and test overheads.

지역 혁신정책의 중심이 중앙정부에서 지자체로 전환되고 있다. 하지만 지역별로 차별화된 지역혁신전략을 수립, 추진하기에 어려움을 겪고 있다. 이는 국가 전체의 차원에서 뿐만 아니라 지역 차원에서도 비효율적이다. 국가내 지역간에 혁신 형태나 특성에 뚜렷한 차이가 있고, 이를 반영하지 못한 혁신정책은 의도한 효과를 거두기 어렵다. 이러한 문제의식 하에 본 연구는 한국에서의 지역간 혁신 형태의 특성과 차이를 밝혀내고, 이를 유형화하여 적절한 정책적 시사점을 제시하고자 하였다. 기존 연구들에서 제시된 지역혁신 관련 지표들을 검토하고, 선정된 지역혁신지표들을 활용하여 다중인자분석과 군집분석 방법을 통해 지역들을 혁신유형별로 구분하였다. 그리고 각 혁신유형별로 드러난 특징과 차이를 기초로 그에 맞는 정책적 방향을 예시하였다. 이러한 결과는 향후 지역별 특성에 적합한 혁신정책 수립에 기여할 것으로 기대된다. The focus of regional innovation policies is shifting from a central government to local governments. No one denies the fact that the innovation will lead regional development and shall be created in such a way that it will be appropriate for regional circumstances. However, the central government and local governments have not arrived yet at a conclusion on what innovation policies are appropriate for regional circumstances. This leads to a consequence that is inefficient not only at a national level, but also at a regional level. This research, given this problem, aims to find out the characteristics and differences in innovation types among the regions in Korea and suggests appropriate policy implications by classifying such characteristics and differences. This research, given these objectives, classified regions in consideration of the various indicators that comprise the innovation suggested by existing related researches and illustrated policies based on such characteristics and differences. In this research clustering analysis based on multiple factor analysis was applied. Supplementary researches on dynamically analyzing stability in regional innovation types, establishing systematic indicators based on the regional innovation theory, and developing additional indicators are necessary in the future.

<P>Copper nanowires (Cu NWs) are suitable material as an electrode for flexible, stretchable and wearable devices due to their excellent mechanical properties, high transparency, good conductivity, and low cost, but oxidation problem limits their practical use and application. In order to use Cu NWs as an electrode for advanced flexible, stretchable and wearable devices attached directly to the skin, the influence of the body temperature on the oxidation of Cu NWs needs to be investigated. In this paper, the oxidation behavior of Cu NWs at high temperature (more than 80 °C) as well as body temperature is studied which has been remained largely questionable to date, and an effective encapsulation method is proposed to prevent the oxidation of Cu NWs electrode in the range of body temperatures.</P>

<P>Research on sustainable and high-efficiency energy devices has recently emerged as an important global issue. These devices are now moving beyond the form of a bulk, rigid platform to a portable, flexible/stretchable format that is easily available in our daily lives. Similar to the development of an active layer for the production of next-generation energy devices, the fabrication of flexible/stretchable electrodes for the easy flow of electrons is also very important. Silver nanowire electrodes have high electronic conductivity even in a flexible/stretchable state due to their high aspect ratio and percolation network structures compared to conventional electrodes. Herein, we summarize the research in the field of flexible/stretchable electronics on energy devices fabricated using silver nanowires as the electrodes. Additionally, for a systematic presentation of the current research trends, this review classifies the surveyed research efforts into the categories of energy production, storage, and consumption.</P>
