Vlsi

www.jntuworld.com INTRODUCTION TO VLSI introduction 1.1 INTRODUCTION The word digital has do a dramatic impact on our society. More world-shattering is a continuous trend towards digital solutions in every last(predicate) areas from electronic instrumentation, control, data manipulation, signals processing, tele communications, etc., to consumer electronics. Development of such solutions has been possible callable to estimable digital system human body and imitate techniques. 1.1.1 VLSI DESIGN The complexity of VLSI being proposeed and intentioned and used like a shot makes the manual of arms approach to design impractical. Design mechanization is the order of the day. With the expeditey technological developments in the last two decades, the placement of VLSI engineering science is characterized by the following: 1 www.jntuworld.com A solid gain in the coat and then the functionality of the ICs. A steady reduction in feature size and hence increa se in the speed of operation as salutary as gate or transistor density. A steady improvement in the predictability of rotary behavior. A steady increase in the variety and size of software tools for VLSI design. The above developments generate resulted in a proliferation of approaches to VLSI design. 1.1.2 VLSI DESIGN FLOW The design process, at various levels, is usually evolutionary in nature. It starts with a given up set of requirements.

Initial design is to be developed and study impact analyst must(prenominal) be considered. The Y-graph (first introduced by D. Gajski) is shown in downstairs figure1 ill ustrates a design flow for most logic chips,! exploitation design activities on the third different axes (domains). Y chart of three major domains, they are: Behavioral domain morphologic domain geometric layout domain 2 www.jntuworld.com Figure 1 Typical VLSI design flow in three domains (Y-chart representation) The design flow starts from the algorithm that describes the behavior of the target chip. The be computer architecture of the processor is first defined. It is mapped onto the...If you want to get a safe essay, order it on our website: BestEssayCheap.com
