Variation aware analysis of bridging fault testing
No full textThis paper investigates the impact of process variation on test quality with regard to resistive bridging faults. The input logic threshold voltage and gate drive strength parameters are analyzed regarding their process variation induced influence on test quality. The impact of process variation on test quality is studied in terms of test escapes and measured by a robustness metric. It is shown that some bridges are sensitive to process variation in terms of logic behavior, but such variation does not necessarily compromise test quality if the test has high robustness. Experimental results of Monte-Carlo simulation based on recent process variation statistics are presented for ISCAS85 and -89 benchmark circuits, using a 45nm gate library and realistic bridges. The results show that tests generated without consideration of process variation are inadequate in terms of test quality, particularly for small test sets. On the other hand, larger test sets detect more of the logic faults introduced by process variation and have higher test quality
Process variation-aware test for resistive bridges
No full textThis paper analyses the behaviour of resistive bridging faults under process variation and shows that process variation has a detrimental impact on test quality in the form of test escapes. To quantify this impact, a novel metric called test robustness is proposed and to mitigate test escapes, a new process variation-aware test generation method is presented. The method exploits the observation that logic faults that have high probability of occurrence and correspond to significant amounts of undetected bridge resistance have a high impact on test robustness and therefore should be targeted by test generation. Using synthesised ISCAS benchmarks with realistic bridge locations, results show that for all the benchmarks, the method achieves better results (less test escapes) than tests generated without consideration of process variatio
Bridging fault test method with adaptive power management awareness
No full textA key design constraint of circuits used in handheld devices is the power consumption, mainly due to battery life limitations. Adaptive power management (APM) techniques aim to increase the battery life of such devices by adjusting the supply voltage and operating frequency, and thus the power consumption, according to the workload. Testing for resistive bridging defects in APM-enabled designs raises a number of challenges due to their complex analog behavior. Testing at more than one supply voltage setting can be employed to improve defect coverage in such systems, however, switching between several supply voltage settings has a detrimental impact on the overall cost of test. This paper proposes a multi-Vdd automatic test generation method which delivers 100% resistive bridging defect coverage and also a way of reducing the number of supply voltage settings required during test through test point insertion. The proposed techniques have been experimentally validated using a number of benchmark circuits
Investigation into voltage and process variation-aware manufacturing test
No full textIncreasing integration and complexity in IC design provides challenges for manufacturing testing. This thesis studies how process and supply voltage variation influence defect behaviour to determine the impact on manufacturing test cost and quality. The focus is on logic testing of static CMOS designs with respect to two important defect types in deep submicron CMOS: resistive bridges and full opens. The first part of the thesis addresses testing for resistive bridge defects in designs with multiple supply voltage settings. To enable analysis, a fault simulator is developed using a supply voltage-aware model for bridge defect behaviour. The analysis shows that for high defect coverage it is necessary to perform test for more than one supply voltage setting, due to supply voltage-dependent behaviour. A low-cost and effective test method is presented consisting of multi-voltage test generation that achieves high defect coverage and test set size reduction without compromise to defect coverage. Experiments on synthesised benchmarks with realistic bridge locations validate the proposed method.The second part focuses on the behaviour of full open defects under supply voltage variation. The aim is to determine the appropriate value of supply voltage to use when testing. Two models are considered for the behaviour of full open defects with and without gate tunnelling leakage influence. Analysis of the supply voltage-dependent behaviour of full open defects is performed to determine if it is required to test using more than one supply voltage to detect all full open defects. Experiments on synthesised benchmarks using an extended version of the fault simulator tool mentioned above, measure the quantitative impact of supply voltage variation on defect coverage.The final part studies the impact of process variation on the behaviour of bridge defects. Detailed analysis using synthesised ISCAS benchmarks and realistic bridge model shows that process variation leads to additional faults. If process variation is not considered in test generation, the test will fail to detect some of these faults, which leads to test escapes. A novel metric to quantify the impact of process variation on test quality is employed in the development of a new test generation tool, which achieves high bridge defect coverage. The method achieves a user-specified test quality with test sets which are smaller than test sets generated without consideration of process variation

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Developing teams and teamwork as a way of building a sustainable quality culture : using an interactive research design
No full textPurposeAdapting to continuously changing environments is a challenge facing todays organisations (Fundin et al., 2018). A way to meet this challenge is by working systematically with Quality Management (QM) e.g., having a focus on the customer, empowering the co-workers, and having a committed leadership (Mohammad and Rad, 2006). The culture within an organization is pointed out as a crucial factor as the organization’s existing culture could hinder or help QM implementation (ibid). According to Ingelsson et al. (2018) the culture that needs to be created should promote a more holistic view on the organization and society as well as continuous work with improvements. Moreover, due to the demanding and complex nature of today’s organisations working in teams becomes more relevant than ever as working in teams makes both co-workers and organizations more effective, flexible, and adaptable for solving complex problems (Kozlowski and Ilgen, 2006).Leaders, and management teams, influences both the organisation’s culture and teams and team performance. According to Schein and Schein (2016), creating, developing, and maintaining an organisational culture is the main task for leaders as their behaviours and attitudes have a great impact on the culture. The same goes for team effectiveness and performance where the leadership is an important element (Colbert et al., 2014). However, working systematically with the culture in an organization is not an easy undertaking (Ingelsson et al., 2018; Sten et al., 2021) and in order to know what to do there is a need to find out where we are, i.e. assessing and monitoring the culture (Bäckström et. al., 2016). In QM research the purpose is often to create value for both organizations and the research community and one research approach aiming at achieving this in cooperation is interactive research. Two basic ideas for interactive research identified by Ellström (2008) are: 1) the triple task of interactive research; contribute to practical results, create scientific knowledge, and develop the competencies of the involved parties, and 2) creation of knowledge by co-operation between practitioners and researchers. He proposes a model in an attempt to describe the interactive part of the research process as “a two-way flow of problems and knowledge between research and practice” (Ellström, 2008, p. 6).The purpose of this paper is to present the design of an interactive research project aiming at changing the culture through the development of teams and teamwork. The purpose is also to present the result from the baseline measurement of quality culture and teamwork. MethodThe presented research project is a collaboration between a municipality and the university with the purpose to develop and improve team-based ways of working and methods to create functional teams and a sustainable quality culture. The participants from the organisation are co-workers from two departments with assumed different cultures and the management team heading both departments. The intention is to develop an interactive project design that it will be developing the management team in parallel and in cooperation with the co-workers. To assess the quality culture, a previously developed and tested questionnaire will be used on both co-workers and leaders and to assess the level of teamwork additional factors will be developed and tested based on previous research (see e.g., Sten et al., 2023). The result from the questionnaire will be analysed using SPSS to examine the baseline as well as any differences or similarities between the groups. FindingsThe first assessment of quality culture and teamwork both from co-workers and the management team will be carried out and analysed during the first quarter and presented in the full paper, as will the generic research process developed in the beginning of the project. The model is inspired by Ellström’s (2008) model of “Knowledge Creation Through Interactive Research” but also incorporates the challenge of working with both co-workers and leaders in parallel. Relevance/contributionThe use of interactive model, such as the one developed and used in this project, can benefit both the research community as well as practice as a way to actively co-create and build culture and develop teamwork in an organization.Developing ways of working with teamwork in management teams in parallel with co-workers organization can accelerate the work with building a sustainable quality culture.

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
