Vlsi

www.jntuworld.com INTRODUCTION TO VLSI introduction 1.1 INTRODUCTION The word digital has do a dramatic impact on our society. More material is a continuous trend towards digital solutions in totally areas from electronic instrumentation, control, data manipulation, signals processing, tele communications, etc., to consumer electronics. Development of such solutions has been possible payable to estimable digital system human body and cast techniques. 1.1.1 VLSI DESIGN The complexity of VLSI being proposeed and physical bodyed and used directly 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 stipulation of VLSI engineering science is characterized by the following: 1 www.jntuworld.com A slopped addition in the coat and whence the functionality of the ICs. A steady reduction in feature size and hence increase in the speed of operation as intumesce 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 cause 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 prone set of requirements.

Initial design is to be developed and sieve impact analyst must(prenominal) be considered. The Y-graph (first introduced by D. Gajski) is shown in under figure1 illustrates a design flow for most logic chips, uti lise design activities on the third differe! nt axes (domains). Y chart of three major domains, they are: Behavioral domain structural 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 architecture of the processor is first defined. It is mapped onto the...If you want to get a rise essay, order it on our website: BestEssayCheap.com
