VLSI – Very Large Scale Integration
Refers to the many fields of electrical and
computer engineering that deal with the
analysis and design of very dense
electronic integrated circuits
Steps to construction in VLSI
Start with a design team
Then move to a design hierarchy
Digital design is usually based on some
type of Hardware Description Language
(HDL)
Design Hierarchy
System Specifications
Abstract high-level model
Logic Synthesis
Circuit Design
Physical Design
Manufacturing
Finished VLSI Chip
VLSI Chip Types
Full-custom
Every circuit is designed for the project
Application-specific integrated circuits
(ASIC)
Allow designers to create IC’s for a
particular application
Semi-custom
Between full-custom and ASIC
Moore’s Law
Gordon Moore (Intel)
The number of transistors on a chip would
double about every 18 months
