VLSI BASIC


Here we are targeting the different basics of VLSI from very starting point (Digital Back ground) till understand the meaning of "What is VLSI".
I have divided the all the post in different chapters and then subsections (As per the below index).

If you think, I have missed any topic, please let me know. I will try to cover that in this section (if possible) else I will let you know by when and where It will be included.

Note: Below Index can be changed because of more detailed sections or New topics but broadly following topics will be covered.

Chapter 1 : Digital Background
Chapter 2 : Semiconductor Background
Chapter 3: CMOS Processing
Chapter 4: CMOS Basics
  • MOS design (type of MOS/PMOS/NMOS/CMOS)
  • CMOS Gates
  • CMOS basic working principle
Chapter 5: CMOS Layout Design
Chapter 6 : MOS Modeling:
  • Differennt Prperties
  • SPICE models
  • Simulation with MicroWind

Chapter 7: Few VLSI terminology
  • Symol, Schematic, CELL, LIBRARY
  • Timing , Power, Area,
  • Driving Strength, Slew, Transition Time, Propagation Delay,
  • Nets, PINS, Clock Circuit, DATA paths
  • Clock paths, Layout , Standard Cells
  • Library Cell Design

Chapter 8: VHDL-Verilog Basics
Other:
1) Twin-tub (Twin -Well) CMOS Process
2) Silicon On Insulator (SOI) CMOS Process

  16. why are higher metal layers used for power and ground rails???

    ReplyDelete
    Replies
    1. There are lot of reasons but for you ...
      1) these are very close to outside Power Pins.
      2) Metal Width and Thickness are large - So less resistive in nature. So less Voltage Drop , if we will use these For Power and Ground.
