2015 Low Power interconnect design Springer 2015
Authors: Sandeep Saini
• Chapter 1 provides the introduction to interconnect modeling and issues in interconnect modeling. Various approximation models for interconnect simula- tions are discussed first along with their advantages and disadvantages. Some improved models are also explained in this unit, which are being used in modern interconnect design. Interconnect shaping and sizing is explained for improved efficiency of the whole system. Then it deals with the existing problems in interconnects and their growing trends with the next coming technologies, the possible solutions, and effectiveness of these solutions.
• Chapter 2 is an introductory chapter for CMOS buffer. CMOS buffer is one of the most basic and researched circuits in modern microelectronics. This circuit is the basis for almost all the ICs existing in today’s world. Various design aspects of CMOS buffers are introduced in this unit along with analysis techniques.
• Chapter 3 gives an introduction to conventional buffer insertion technique for the purpose of signal restoration and delay reduction. Benefits of buffer insertion in linear interconnect and their use in delay and noise reduction are explained along with various buffer insertion existing in literature. This chapter provides the understanding of basics about propagation delay, power dissipation, and design criteria. It is also shown how buffer insertion is becoming a bulky technique and going to consume more and more resources in incoming technologies. Limita- tions of buffer insertion technology in terms of area and power consumption are discussed in the end.
• Chapter 4 introduces Schmitt trigger. History, invention, and basic circuit implementation of Schmitt trigger are discussed in early sections of the chapter. Implementation and working of Schmitt trigger is discussed in detail. CMOS Schmitt triggers are mentioned in the later sections of the chapter. Benefits of Schmitt trigger over buffer for the purpose of signal restoration and delay reduction are discussed in the end.
• Chapter 5 introduces another category of techniques in interconnect design called Bus Coding. The concept of bus coding is to change the data on a bus at input end and then retrieve it back with decoding algorithm. While encoding the data, we try to save delay or power consumed in transmission of this data. This chapter provides the basics about buses and the existing problems. And with various bus coding techniques, it discusses the solution to existing problems. Delay is one of the most important factors in modern high speed communicating world. Thus along with power efficient design, we have to also focus on high speed communication. Different schemes are discussed in this chapter along with their comparisons.
