LABORATORY OBJECTIVE

The experiments covered in this laboratory are

synchronized with its theoretical part, so that

students might be able to understand the practical

aspects of the course. The main objective of this

laboratory is to give:

Introduction to different steps used in the

design of digital systems according to

industrial standards

Complete knowledge of simulation software

(e.g. Spice and Electric VLSI System Design)

used in industry for VLSI design

Comprehensive detail of different solid state

pulse circuits and their applications

ELECTRIC VLSI DESIGN SYSTEM

Digital Electronics Lab has Electric VLSI Design

System installed on each of its high performance

dual core processor desktop. The Electric VLSI

Design System is an EDA tool that is used to draw

integrated circuit layout and schematics. It can

also handle hardware description languages such

as VHDL and Verilog.

Laboratory Project

At the end of the lab, a final project of the lab is given to

the students, so that they might be able to encapsulate

the concepts gained during whole the laboratory

sessions. The project given to the students who have

taken the lab most recently was:

Layout of a 4-Bit Adder

The students had to draw the layout of the 4-bit

adder using Electric VLSI Design System and

verify it with simulator IRSIM.
