Thermal and electrical stress phases are commonly applied to automotive devices at the end of manufacturing test to give rise to early life latent failures. This paper proposes a new methodology to optimize the stress procedures during the Burn-In phase. In the proposed method, stress of CPU, RAM memory and FLASH memory are run in parallel using DMA and CACHE interventions. The paper reports also...
Reliability testing is increasingly used not only to reduce Infant Mortality effects, but also for Reliability Characterization. This paper first discusses the characteristics of the stimuli to be used during Reliability Characterization experiments, and outlines the importance of adopting a functional approach. Secondly, the paper describes a novel approach to automatically generate suitable stress...
Software-based self-test (SBST) is increasingly used for testing processor cores embedded in SoCs, mainly because it allows at-speed, low-cost testing, while requiring limited (if any) hardware modifications to the original design. However, the method requires effective techniques for generating suitable test programs and for monitoring the results. In the case of processor core testing, a particularly...
The car market shows a clear trend towards an increasing presence of electronic devices in engine control systems, due to a strong market drive towards high-performance control systems. Empirical evidence shows that a conventional screening approach only targeting system functionality is not enough to reach the desired high-quality targets. In this paper a methodology is presented to generate a set...
An approach to grey level texture analysis is extended to colour images. Three colour texture classifiers using the CCR feature space are proposed. Textural information is derived from luminance plane by means of coordinated clusters transform along with chrominance features treated separately. The classifiers differ, basically, in the use of RGB and YIQ colour spaces. The main objective of this work...
