VLSI?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 teamThen move to a design hierarchy

Digital design is usually based on some type of Hardware Description Language (HDL)

Design HierarchySystem Specifications

Abstract high-level model

Logic Synthesis

Circuit Design

Physical Design

Manufacturing

Finished VLSI Chip

VLSI Chip TypesFull-custom

Every circuit is designed for the project

Application-specific integrated circuits (ASIC)

Allow designers to create IC’s for a particular application

Semi-customBetween full-custom and ASIC

Moore’s Law

Gordon Moore (Intel)The number of transistors on a chip would double about every 18 months
