Hello All,

I just started designing the Pong Game on FPGA. I need help from people who know how to implement it on FPGA and also the pitfalls faced.

I'll be eagerly waiting for your response.
Thank you all.

Read these well, then ask specific questions.

The frequency depends on the framerate. Google knows all about it.

You can use any screen you like but since you have to ask I doubt it is a good idea since it can be quite complicated to interface to it.

The refresh is done correctly.

You don't need RAM for pong unless the screen is updated in the wrong order. Pong was implemented with a handful of TTL chips originally.


It does not seem like either of you have read the page about pong or have understood how it works. Replicate exactly what is done on the page, don't change anything until it is working and you understand every part of it.

I just went through the each and every aspect of the design. But I still got some doubts :

The working of the mouse is modified by using a NAND gate to generate the Quad Signals. If I have to use the normal mouse PS/2, how should i interface it to the Cyclone FPGA.

There is a reason the mouse was modified, it made everything much simpler. A PS/2 mouse uses a serial protocol that is a lot more difficult to decode. many people have done it before you so you should be able to find the code on Google.

Thank You Mr.Kristallo, You have been very helpful for me since i started working on the project.
The thing is, I have to submit this project to the course instructor by Nov-15th....Now i have finished all the theoretical work on this and i will dive into the real implementation on FPGA...

I want to make the paddle moment using 2 switches placed on the breadboard and connect them to the : Quad A and Quad B Signals.

What do u say about this!...I think it works right.

Waiting for u'r reply

Using two swithes is an excellent idea that will work very well.

You need to divide down the system clock to get a suitable speed of movement. 50 Hz would be a suitable frequency to start with, it would make sure the paddle is controllable.

At every rising edge of the divided clock you check the buttons, if button 1 is pressed then PaddlePosition <= PaddlePosition - 1 if button 2 is pressed then PaddlePosition <= PaddlePosition + 1.

Hello all,

I did some home work by going thro the sites mentioned.I am keeping track of the things happening in this project.

The idea of using 2 swithces is nice but, I have some doubt in dividing the system frequency from 25MHz to 50 Hz....

How it can be achieved? can anyone suggest me a solution!

I am excited to know the solution, and I will try to implement using that procedure.

Thank u

Its very easy to implement :

1. Use Frequency Dividers,
2. Counters

if u have any doubts u can feel free to ask me.

25 000 000 / 50 = 500 000
The nearest power of two is 2^19 = 524 288
So make a 19 bit counter and use the most significant bit as the clock for the buttons.

Hi There,

I need some suggestions:

1. How to Configure the IO pins of the FPGA [Cyclone-II], so that I can Connect the Push Buttons.

2. How to implement the multiple ball.

Please I need the information very urgently. There is no time left for me to submit the project in the School.

Thank u

THANKS FOR YOUR GAME!
I have a problem about these expressions:
if(~&PaddlePosition) PaddlePosition <= PaddlePosition + 1;
if(|PaddlePosition) PaddlePosition <= PaddlePosition - 1;
What do they mean?At which condition will the expression be ture?

Thank U!!!

hey so i am in a pickle. I have an Altera DE2 fpga board and am using the quartus 2 software. I'm using an lcd monitor and checked it with the fpga control panel to make sure it works fine. I got the code for the pong game from your site and compiled it fine but when i program it to the board nothing happens. any suggestions?!
