VLSI Design
Presented By:
 VLSI Design
Very large-scale integration is the process of creating an
integrated circuit by combining millions or billions of MOS
transistors onto a single chip.
VLSI began in the 1970s when MOS integrated circuit chips
Were developed and then widely adopted, enabling
complex semiconductor and telecommunication
technologies.
 Verilog
Verilog is a hardware description language used to
model electronic systems. It is most commonly
used in the design and verification of digital circuits
at the register transfer level of abstraction.
Applied to electronic design, Verilog is intended to be
used for verification through simulation, for timing
analysis, for test analysis (testability analysis and
fault grading) and for logic synthesis.
 FPGA
Field-programmable gate arrays (FPGAs) are devices
whose physical attributes can be manipulated through the
use of hardware description languages (HDLs) which bridge
the gap between programming software and programming
hardware.
Project
Parking Management system:
 A parking lot has a fixed number of parking
spots, of which some are empty.
 We have to display either the number of parked
cars or the number of vacant parking spots to a
car coming into the parking lot.

Steps for Designing
 Decide the number of slots and take input ports
accordingly.
 Each slot has a sensor that sends logic signal 1
whenever a car is parked there.
 Count the number of logic 1’s received by all the
sensors in the lot.
 Store the count on a temporary variable and
display that on a 7 segment display.
Implementation
•For simulation, the number of cars is stored as a decimal
number, which can be displayed on a 7 segment display for its
FPGA implementation.
