Matlab,  Matlab simulink: We can use matlab in many and very large applications of mathmatical calculations and solutions, in many fields of mathmatical theories and solutions, also in data base distrubitions, matlab also have a part of matlab simulink used in control systems, thermodynamics, signal transformations and treatement, high frequency controls, transport, many and many systems in higher technoligies using Matlab. Today i will show you some application for engineers in electricity and control engineers, in mathmatical operations in research also,... Nous pouvons utiliser matlab dans de nombreuses et très grandes applications de calculs et de solutions mathématiques, dans de nombreux domaines des théories mathématiques et des solutions, également dans les distrubitions de base de données. Matlab possède également une partie de matlab simulink utilisée dans les systèmes de contrôle, la thermodynamique, les transformations de signal et le traitement , Des contrôles à ...

CH1: systems of numeration and codes Introduction in digital electronics, The use of digital components and digital systems is using nowadays too much, wide applications... There is only to look around us, and in all the applications we found electronics and microelectronics, The explosion of the microelectronics and the architecture are giving a complex systems and producesd very high complex applications in many fields. A bigger and bigger number of applications are (digital camera, car, industry, washing machine, etc.) using the digital electronics.  We found, until the appearance of the microprocessor, two big sectors in the field of the digital systems.  This division remained at the manufacturer's of computers where we  still find: · the material department (hardware) · the software department or the programming (software)  The appearance of the microprocessor has the effect of diminishing the importance of the hardware and of causing a displacement of ...

Cadence (Outil de simulations et analyses) C’est un logiciel, on a utilisé beaucoup de fois en architecture des circuits, simulations, tests et analyses. Il a compose et a consisté de simulateur Orcad , Spice netlist, simulateur PCB, Simulateur Layout,… Aussi on peut faire Analyse DC, AC, Transient,.., montecarlo,… 1-     Analyse DC, on utilisant un amplificateur opérationnel avec ces propriétés en modèle Spice. On analyse les C/CS tension/courant, on va appliqué tension entre -15v et 15v, et aussi -12v et 12v.                                                          Fig-1 Composants OP-Amp, Source de tension, 3 résistors, 1 terre. Choix analyse type DC, -15v,+15v, avec step 1. On a vu le schéma électronique et sa réponse en tension type DC (le choix par un marquer en vert,…comme dans le schéma). ...

DFT design for testability: Testing Basics • Testing and debug in commercial systems have many parts – What do I do in my design for testability? – How do I actually debug a chip? – What do I do once I’ve debugged a chip? • Two rules always hold true in testing/debug – If you design a testability feature, you probably won’t need to use it • Corollary: If you omit a testability feature, you WILL need to use it – If you don’t test it, it won’t work, guaranteed Two Checks • There are two basic forms of validation – Functional test: Does this chip design produce the correct results? – Manufacturing test: Does this particular die work? Can I sell it? • What’s the difference? – Functional test seeks logical correctness • >1 year effort, up to 50 people, to ensure that the design is good – Manufacturing test is done on each die prior to market release • Send your parts through a burn-in oven and a tester before selling them. Testing Costs Are ...
