Objectives & Courses
DLD Lab Venue:
Computer Interfacing Lab
First Floor, Electrical Department
Lab Venue
The Digital Logic Design Lab
(DLD Lab) is one of the most
important and well equipped lab of
the Department of Electrical
Engineering at University of
Engineering and Technology, Lahore.
This lab is conducted at the
Computer Interfacing Lab situated at
the first floor of the Electrical
Engineering Department.
Scope of the Lab
The DLD Lab is for
undergraduate coursework related to
the course EE131. It is one of the
core modules of B. Sc. Electrical
Engineering therefore the lab has a
significant importance in the
department.
Related Courses
This lab is designed such that the
students get a hands on familiarity
with the concepts they come across
in the course EE131 that is the Digital
Systems course. This is an
undergraduate course which deals
with the basics of digital systems
design and is a core module of the
B. Sc. Electrical Engineering
coursework as it provides the
prerequisites for advance courses in
digital electronics. Because of the
significance of this course the DLD
Lab has been carefully designed to
meet the course requirement.
Brief Overview of the Lab
The Lab is well equipped with
both hardware and software facilities
required by the students to perform
the necessary experiments designed
for this lab. Details of the lab
equipment has been discussed in a
proceeding section.
Experiments are designed in
such a way that the students become
well aware of the concepts they learn
in the theory sessions. A list of
experiments that are conducted in
this lab has also been mentioned in a
proceeding section.
Experiments are related to both
digital hardware and Verilog
Programming.

Lab Description & Experiments
Lab Description
The Experiments in the
Lab have been divided into
two major portions:
• Hardware Labs
• Hardware Description
Language (Verilog) Labs
Hardware Labs have
been designed to
familiarize students with the
Combinational Digital Logic
Design and Sequential
Digital Logic Design
through the implementation
of Digital Logic Circuits
using ICs of basic logic
gates and some simple
digital logic circuits.
HDL (Verilog) Labs have
been designed to
familiarize students with the
HDL based Digital Design
Flow. These labs introduce
students with different
levels of coding available in
Verilog i.e. Gate level,
Dataflow level and
Behavioral level. Xilinx ISE
7.1 tools have been used in
these labs. Finally, the
skills learnt in the HDL
labs are employed to
implement some digital
logic circuits on Spartan-3
FPGA, using Xilinx Starter
Kit Development Board.
A Lab Demonstration
Expected Outcomes
With the help of the two
threads of the lab
mentioned above, students
will have clear
understanding of all the
three paradigms of
implementation of digital
logic circuits:
• Implementation using
ICs for basic logic gates
and simple circuits
• Implementation
through the Development
of Dedicated IC(ASIC)
• Implementation
through Reconfigurable
Logic (i.e. FPGA)
This makes students
adept in basic concepts
involved in digital logic
design. The lab contributes
a lot to the basic learning of
digital systems.
This shows the
indispensability of the
DLD Lab.
List of Experiments
List of experiments is
given on page 5 and 6. As
mentioned before the lab
has two major portions
therefore there are two lists
of experiments one related
to the hardware labs and
the other related to the
hardware description
language (verilog) labs. All
these experiments are
mandatory and each lab is
followed by specially
designed assignments.

equipped with all the
hardware required to
conduct the above
mentioned experiments.
The hardware resources of
the lab are:
• Pentium-IV PCs (with
MS WinXp OS)
• Hardware trainers for
logic circuit design and
analysis
• Electronic Chips of all
digital gates
• Spartan-III FPGA
board kits
• Power Supplies
These resources allow
the students to have a
hands on experience of
basic digital logic design
concepts. This activity
greatly leverages what the
students learn in the theory
sessions.
Software Resources
The lab also consists of
the software resources
required by the students
namely:
• Veriwell
• ModelSim
• Xilinx IDE
• Matlab
A Digital Circuit Board
Software resources are
equally important as
hardware resources are.
These software resources
are sufficient for the
students to perform
experiments. These
softwares provide the
students with the
necessary platform to work
on HDL that is the Verilog.
These softwares are also
required to work with the
sophisticated hardwares
like Spartan-III FPGA
boards.
The lab has all the
resources whether related
to hardware or software so
that the students become
adept in the basic field of
digital electronics.
Students are
encouraged to use the lab
resources to perform
activities and
experiments which help
them strengthen their

Lab Staff
Like other labs of the
department there is a
trained and able staff
consisting of skilled lab
technicians that take care
of the lab equipment.
They also guide
students about handling
the lab equipment and the
precautionary measures
required for the students
while working in the lab.
