SEMESTER II SESSI 1011 

SEE 4743 : BASIC DIGITAL VLSI

Prerequisite

Digital System

Objective

To introduce students to basic techniques to design and implement digital VLSI system.

Synopsis

1.     This course introduces students to VLSI technology. A historical perspective on the evolution of integrated circuit technology is covered. Important issues when designing a VLSI circuit are discussed.

2.     MOS transistors are studied in detail, including their characteristics, structure, switch-level behaviour, and current equation. SPICE model of a MOS transistor is also described. The simplest circuit, an inverter, is studied in detail. Its voltage-transfer characteristic, noise margin and how to control the inversion point is investigated.

3.     How an IC is fabricated is described. Fabrication processes are elaborated. Layout, design rules and stick diagram are explained.

4.     This course teaches how to design circuits. Several logic families will be introduced. Advantages and disadvantages of each logic design style are explained. Delay and power performance of each logic family is also compared. Latch, flip-flop and memory circuits are also covered.

5.     Interconnect issues, when various components are connected together, are elaborated. To gain a better understanding of a complete design, a subsystem design in the form of adder circuits is included.

Course outcomes:

At the end of the course the students should be able to:

CO1

Understand the integrated circuit technology and design process.

CO2
