The expansion of Wireless Systems-on-Chip leads to a rapid development of new design and test methods. In this paper, the test benches defined for design validation or characterization of AMS & RF SoCs are first optimized and then re-used for production testing. Although the original validation test set allows the verification of both design functionalities and performances, this test set is no...

LIFETIME VALIDATION OF DIGITAL SYSTEMS VIA FAULT MODELING AND TEST GENERATION by Hussain Said Al-Asaad Chair: John P. Hayes The steady growth in the complexity of digital systems demands more efficient algorithms and tools for design verification and testing. Design verification is becoming increasingly important due to shorter design cycles and the high cost of system failures. During normal o...

The authors present some ideas on developing a validity statement based on a Tu-ring test { like methodology with a set of test cases. The (anonymous) solutions of these test cases will be rated by a panel of expert va-lidators. Their ratings are used for both the assessement of the experts' competence and the assessment of the system's validity. The objective of this is, of course, to make the...

Shear wave velocity is a basic engineering tool required to define dynamic properties of soils. In many instances it may be preferable to determine Vs indirectly by common in-situ tests, such as the Standard Penetration Test. Many empirical correlations based on the Standard Penetration Test are broadly classified as regression techniques. However, no rigorous procedure has been published for c...

Veryfew attempts have been made in the past to develop instruments to measure pragmatic knowledge of second language (L2) learners. The absence of such instruments in the literature of English language teaching (ELT) underscores the need for the researchers to develop new tests that are specifically designed to assess this crucial but less explored aspect of language learners’ (LLs) knowledge. ...

INTRODUCTION External validation studies are essential to study the generalizability of prediction models. Recently a permutation test, focusing on discrimination as quantified by the c-statistic, was proposed to judge whether a prediction model is transportable to a new setting. We aimed to evaluate this test and compare it to previously proposed procedures to judge any changes in c-statistic ...

The European Centre for the Validation of Alternative Methods (ECVAM) was established by the European Commission in 1991, to co-ordinate the validation of alternative methods at the European Union level, to establish a database on alternative methods, and to promote dialogue among all the interested parties, in order to secure the international recognition and acceptance of validated alternativ...

The quality of software systems depends strongly on their architecture. For this reason, taking into account non-functional requirements at architecture level is crucial for the success of the software development process. Early architecture model validation facilitates the detection and correction of design errors. In this research, the authors are interested in security critical systems, whic...

New methodologies based on functional testing and built-in self-test can narrow the gap between necessary solutions and existing techniques for processor validation and testing. We present a versatile automatic functional test generation methodology for microprocessors. The generated assembly instruction sequences can be applied to both design validation and manufacturing test, especially in hi...

BACKGROUND Validation is the process of providing evidence that tests and questionnaires are adequately and appropriately fulfilling the purposes for which they are developed. In this special issue, experts from several countries describe specific approaches to test validation and provide examples of their approach. These approaches and examples illustrate the validation framework implied by th...
