Logic optimizationLogic optimization is a process of finding an equivalent representation of the specified logic circuit under one or more specified constraints. This process is a part of a logic synthesis applied in digital electronics and integrated circuit design. Generally, the circuit is constrained to a minimum chip area meeting a predefined response delay. The goal of logic optimization of a given circuit is to obtain the smallest logic circuit that evaluates to the same values as the original one.
High-level synthesisHigh-level synthesis (HLS), sometimes referred to as C synthesis, electronic system-level (ESL) synthesis, algorithmic synthesis, or behavioral synthesis, is an automated design process that takes an abstract behavioral specification of a digital system and finds a register-transfer level structure that realizes the given behavior. Synthesis begins with a high-level specification of the problem, where behavior is generally decoupled from low-level circuit mechanics such as clock-level timing.
Metastability (electronics)In electronics, metastability is the ability of a digital electronic system to persist for an unbounded time in an unstable equilibrium or metastable state. In digital logic circuits, a digital signal is required to be within certain voltage or current limits to represent a '0' or '1' logic level for correct circuit operation; if the signal is within a forbidden intermediate range it may cause faulty behavior in logic gates the signal is applied to.
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.
Functional verificationFunctional verification is the task of verifying that the logic design conforms to specification. Functional verification attempts to answer the question "Does this proposed design do what is intended?" This is complex and takes the majority of time and effort (up to 70% of design and development time) in most large electronic system design projects. Functional verification is a part of more encompassing design verification, which, besides functional verification, considers non-functional aspects like timing, layout and power.
Espresso heuristic logic minimizerThe ESPRESSO logic minimizer is a computer program using heuristic and specific algorithms for efficiently reducing the complexity of digital logic gate circuits. ESPRESSO-I was originally developed at IBM by Robert K. Brayton et al. in 1982. and improved as ESPRESSO-II in 1984. Richard L. Rudell later published the variant ESPRESSO-MV in 1986 and ESPRESSO-EXACT in 1987. Espresso has inspired many derivatives. Electronic devices are composed of numerous blocks of digital circuits, the combination of which performs the required task.
Comparison of EDA softwareThis page is a comparison of electronic design automation (EDA) software which is used today to design the near totality of electronic devices. Modern electronic devices are too complex to be designed without the help of a computer. Electronic devices may consist of integrated circuits (ICs), printed circuit boards (PCBs), field-programmable gate arrays (FPGAs) or a combination of them. Integrated circuits may consist of a combination of digital and analog circuits.
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.
Fonderie (électronique)Une fonderie (foundry en anglais) est, dans l'industrie électronique, une entreprise spécialisée dans la fabrication des dispositifs à semi-conducteurs, dont les puces électroniques et travaillant pour le compte d'autres entreprises spécialisées dans leur conception. L'usine de production est aussi couramment désignée sous le nom de fab (de l'anglais fabrication plant). Le cœur d'une « fab » réside dans sa salle blanche, une zone où l'environnement est contrôlé pour éviter toute micro-poussière et où la moindre micro-vibration est proscrite.
