Lecture-1

Many disciplines have contributed to the

current state of art in VLSI design:

Solid-state physics.

Materials science. Lithography and fab.

Device modeling.

Architecture.

Algorithms.

CAD tools.

Circuit design & layout.

Lecture-1

Lets get started

We will review (learn for first time?) MOS

physics.

Why MOSFETs?

CMOS circuits dissipate power only when switching

(they do use power when not switching, but is much

less than other circuits).

This allows for more circuits to be placed on one die.

VLSI Design Flow

Definitions and Terminology:

Abstraction; refinement.

Synthesis; analysis; optimization.

Extraction ; generation.

Design process traverses iteratively among three

domains shown in Gajski Y chart.
