2.  A field-programmable gate array (FPGA) is
an integrated circuit designed to be configured
by a customer or a designer after
manufacturing .
 The FPGA configuration is generally specified
using a hardware description language(HDL),
similar to that used for an application-specific
integrated circuit(ASIC).

3.  FPGA(Field Programmable Gate Arrays) have
large sources of logic gates and ROM memory.
The logic units used in FPGA are typically
implemented using :
 LUTs
 NAND gates
 Transistors
 Multiplexer

4.  A seven-segment display (SSD), or seven-
segment indicator, is a form of
electronic display device for displaying decimal
numerals that is an alternative to the more
complex dot matrix displays.
 Applications:
Seven-segment displays are widely used
in digital clocks, electronic meters, basic
calculators, and other electronic devices that
display numerical information.

5.  The seven elements of the
display can be lit in different
combinations to represent
the arabic numerals.
 The segments of a 7-segment
display are referred to by the
letters A to G, where the
eighth segment is used for the
display of non-integer
numbers.

6.  Seven-segment displays
may use a liquid crystal
display(LCD), a light-
emitting diode(LED) for
each segment, or other
light-generating or
controlling techniques
such as cold cathode gas
discharge, vacuum
fluorescent, incandescen
t filaments, and others.

8.  The above block diagram consist of 2 outputs and 2 inputs.
 Firstly a delay and count is given by the FPGA clock which generates
increasing numbers on the seven segment displays. Inputs: 4 Slide
Switches and a Push Button.
 The 4 slide switches are used to stop the counter of each seven segment
display, that is, as soon as we switch on the switch, the number on the
corresponding seven segment freezes.
 The push button is used to reset the counter, as the button is pressed, all
the four seven segment displays go back to zero and start over again
afresh. Outputs: 4 Seven Segment Display and all LEDs.
 The seven segment displays are used throughout the project to display the
numbers on them in increasing fashion or freeze state. The main purpose
of using LEDs in this project is to indicate that the player wins the game
as it will glow only when all the switches are high as well as the numbers
on all the seven segment displays are identical.

9. The Nexys 3 Spartan 6 FPGA board consists of five push
buttons of which we make use of the central push button for
the reset purpose. We make use of all 4 seven segment LED
displays available on the board and also 4 out of 8 slide
switches are used. This board has 8 LED and we use all of
them to signify the winning situation. The FPGA board
connects to the Xilinx software in computer with the help of a
USB cable connected to the USB port on the board . This USB
cable supplies power to the FPGA board and is also used to
implement the program code on the hardware. The main
component of the hardware is the application based
integrated circuit (ASIC) named as Nexys 3 Spartan-6 which
works at the frequency of 50 MHz .

15.  APPLICATION:
This implementation of lucky 7 can be used in casino
gaming instead of the game slots. It can also be used in
the restaurants for the order number machines which
would look fascinating to display a customer’s order
number while glowing LED.
 RESULT
After the implementation of a code written in Xilinx
based on the sequence of the block diagram, the numbers
run from 0 to 9 on all the four seven segment display and
are controlled by individual switches. When the switch is
turned on the number on the corresponding seven
segment freezes. When all the four switches are on the
when the number frozen on the four seven segments are
same, the LED lights on the Spartan 6 board glow,
representing the winning position.
