EE-429: Fundamentals of VLSI design

The course introduces the fundamentals of digital integrated circuits and the technology aspects from a designers perspective. It focuses mostly on transistor level, but discusses also the extension to large digital semicustom designs. ...

Description

Cette séance de cours couvre les principes fondamentaux de la conception VLSI liés à la SRAM, y compris la structure des matrices de mémoire pour une meilleure densité, différents types de mémoires, le mélange et la correspondance dans la hiérarchie de la mémoire, l'importance de la SRAM dans la conception des circuits intégrés et l'organisation physique du réseau de cellules de bits. Il explique comment les mémoires regroupent les éléments de stockage dans des tableaux personnalisés, l'organisation logique et physique des mémoires et l'accès au tableau avec les périphériques de base.

Andreas Peter Burg

Andreas Burg was born in Munich, Germany, in 1975. He received his Dipl.-Ing. degree in 2000 from the Swiss Federal Institute of Technology (ETH) Zurich, Zurich, Switzerland. He then joined the Integrated Systems Laboratory of ETH Zurich, from where he graduated with the Dr. sc. techn. degree in 2006. In 1998, he worked at Siemens Semiconductors, San Jose, CA. During his doctoral studies, he was an intern with Bell Labs Wireless Research for a total of one year. From 2006 to 2007, he held positions as postdoctoral researcher at the Integrated Systems Laboratory and at the Communication Theory Group of the ETH Zurich. In 2007 he co-founded Celestrius, an ETH-spinoff in the field of MIMO wireless communication, where he was responsible for the ASIC development as Director for VLSI. In January 2009, he joined ETH Zurich as SNF Assistant Professor and as head of the Signal Processing Circuits and Systems group at the Integrated Systems Laboratory. In January 2011, he became a Tenure Track Assistant Professor at the Ecole Polytechnique Federale de Lausanne (EPFL) where he is leading the Telecommunications Circuits Laboratory in the School of Engineering. In June 2018 he was promoted to the role of a Tenured Associate Professor. In 2000, Mr. Burg received the Willi Studer Award and the ETH Medal for his diploma and his diploma thesis, respectively. Mr. Burg was also awarded an ETH Medal for his Ph.D. dissertation in 2006. In 2008, he received a 4-years grant from the Swiss National Science Foundation (SNF) for an SNF Assistant Professorship. In his professional career, Mr. Burg was involved in the development of more than 25 ASICs. He is a member of the IEEE and of the European Association for Signal Processing (EURASIP).

Memory cell (computing)

The memory cell is the fundamental building block of computer memory. The memory cell is an electronic circuit that stores one bit of binary information and it must be set to store a logic 1 (high voltage level) and reset to store a logic 0 (low voltage level). Its value is maintained/stored until it is changed by the set/reset process. The value in the memory cell can be accessed by reading it. Over the history of computing, different memory cell architectures have been used, including core memory and bubble memory.

Conception assistée par ordinateur pour l'électronique

La CAO électronique (pour Conception assistée par ordinateur électronique), nommée également en anglais EDA (pour Electronic design automation), est la catégorie des outils servant à la conception et la production des systèmes électroniques allant des circuits imprimés jusqu'aux circuits intégrés. Le terme CAO est aussi utilisé pour désigner la CAO mécanique, la conception assistée par ordinateur et la fabrication assistée par ordinateur en électronique et en électrotechnique.

Computer memory

Computer memory stores information, such as data and programs for immediate use in the computer. The term memory is often synonymous with the term primary storage or main memory. An archaic synonym for memory is store. Computer memory operates at a high speed compared to storage which is slower but less expensive and higher in capacity. Besides storing opened programs, computer memory serves as disk cache and write buffer to improve both reading and writing performance.

Field-programmable gate array

A field-programmable gate array (FPGA) is an integrated circuit designed to be configured after manufacturing. The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC). Circuit diagrams were previously used to specify the configuration, but this is increasingly rare due to the advent of electronic design automation tools. FPGAs contain an array of programmable logic blocks, and a hierarchy of reconfigurable interconnects allowing blocks to be wired together.

Mémoire vive dynamique

La mémoire vive dynamique (en anglais DRAM pour Dynamic Random Access Memory) est un type de mémoire vive compacte et peu dispendieuse. La simplicité structurelle de la DRAM — un pico-condensateur et un transistor pour un bit — permet d'obtenir une densité élevée. Son inconvénient réside dans les courants de fuite des pico-condensateurs : l'information disparaît à moins que la charge des condensateurs ne soit rafraîchie avec une période de quelques millisecondes. D'où le terme de dynamique.
