Circuit designThe process of circuit design can cover systems ranging from complex electronic systems down to the individual transistors within an integrated circuit. One person can often do the design process without needing a planned or structured design process for simple circuits. Still, teams of designers following a systematic approach with intelligently guided computer simulation are becoming increasingly common for more complex designs.
Standard cellIn semiconductor design, standard-cell methodology is a method of designing application-specific integrated circuits (ASICs) with mostly digital-logic features. Standard-cell methodology is an example of design abstraction, whereby a low-level very-large-scale integration (VLSI) layout is encapsulated into an abstract logic representation (such as a NAND gate). Cell-based methodology – the general class to which standard cells belong – makes it possible for one designer to focus on the high-level (logical function) aspect of digital design, while another designer focuses on the implementation (physical) aspect.
Software verification and validationIn software project management, software testing, and software engineering, verification and validation (V&V) is the process of checking that a software system meets specifications and requirements so that it fulfills its intended purpose. It may also be referred to as software quality control. It is normally the responsibility of software testers as part of the software development lifecycle.
Application-specific integrated circuitvignette|Un ASIC. Un ASIC (acronyme de l'anglais application-specific integrated circuit, littéralement « circuit intégré propre à une application ») est un circuit intégré spécialisé. En général, il regroupe sur la même puce un ou sur mesure. thumb|Autre exemple de puce ASIC. L'intérêt de l'intégration est de réduire les coûts de production et d'augmenter la fiabilité. Avantage pour le maître d'œuvre : un contrôle total du produit et un coût de production réduit.
Passive daytime radiative coolingPassive daytime radiative cooling (PDRC) is a renewable cooling method proposed as a solution to global warming of enhancing terrestrial heat flow to outer space through the installation of thermally-emissive surfaces on Earth that require zero energy consumption or pollution. Because all materials in nature absorb more heat during the day than at night, PDRC surfaces are designed to be high in solar reflectance (to minimize heat gain) and strong in longwave infrared (LWIR) thermal radiation heat transfer through the atmosphere's infrared window (8–13 μm) to cool temperatures during the daytime.
Intégrité du signalvignette| Diagramme de l'œil simulé affichant une forme d'onde d'un signal d'une mémoire vive dynamique DDR3. En électronique logique et numérique, l'expression intégrité du signal ou SI (pour signal integrity en anglais) désigne la qualité du signal électrique qu'il est nécessaire de maintenir pour que le système effectue la tâche pour laquelle il est conçu. Le souci de l'intégrité du signal surgit dans la conception d'un nouveau dispositif électronique au moment de passer du schéma de principe au dessin de sa réalisation matérielle.
Business process modelingBusiness process modeling (BPM) in business process management and systems engineering is the activity of representing processes of an enterprise, so that the current business processes may be analyzed, improved, and automated. BPM is typically performed by business analysts, who provide expertise in the modeling discipline; by subject matter experts, who have specialized knowledge of the processes being modeled; or more commonly by a team comprising both. Alternatively, the process model can be derived directly from events' logs using process mining tools.
CorrosionLa corrosion désigne l'altération d'un matériau par réaction chimique avec un oxydant (le dioxygène et le cation H+ en majorité). Il faut en exclure les effets purement mécaniques (cela ne concerne pas, par exemple, la rupture sous l'effet de chocs), mais la corrosion peut se combiner avec les effets mécaniques et donner de la corrosion sous contrainte et de la fatigue-corrosion ; de même, elle intervient dans certaines formes d'usure des surfaces dont les causes sont à la fois physicochimiques et mécaniques.
Deep-level transient spectroscopyDeep-level transient spectroscopy (DLTS) is an experimental tool for studying electrically active defects (known as charge carrier traps) in semiconductors. DLTS establishes fundamental defect parameters and measures their concentration in the material. Some of the parameters are considered as defect "finger prints" used for their identifications and analysis. DLTS investigates defects present in a space charge (depletion) region of a simple electronic device. The most commonly used are Schottky diodes or p-n junctions.
DFXLe sigle anglais DFX, formé à partir des initiales de Design For X, est l'ensemble des règles à observer lors de l'étude, la conception d'un circuit intégré ou d'un système électronique ou encore de tout système afin d'améliorer le terme qui remplacerait la lettre X.
