Data Transfer from PC to FPGA through USB

Hallo guys,

I'm pretty new to hardware programming. I'm currently working on a projec
and I have to create a communication channel between my PC and FPGA (Xilin
Virtex 5 model) through a USB port.

At the end of the day, it should be able to use a matlab script to sen
data from PC to FPGA.

For example if I send 110000 from my PC, it should light some LEDs on m
FPGA.

I don't know how to establish this communication channel.

ANY HELP ?

You might want to look into the HDL Verifier product which allows
FGPA-in-the-Loop simulation with a variety of popular FPGA boards over
Gigabit Ethernet. You can also use this product to co-simulate MATLAB
and an HDL simulator such as ModelSim from Mentor Graphics.

If you really need USB, I would look at the FTDI chipsets for serial
port emulation over USB. They are easy to use and readily available.

Disclaimer: I work as a developer for The MathWorks.

Good luck!

You might take a look at FTDI interface chips. They have a variety of
solutions as does Cypress Semi.

You don't mention how much performance you need. Is it MB/sec or
KB/sec? That makes a huge difference to your approach. Also - USB2 or
USB3?

FWIW, OpenCores lists a USB 1.1 and a USB 2.0 core. But the FTDI chip
comes with Windows drivers, which will vastly simplify your life, if your
prof will let you do it that way.

Then make your life easy: use an usb -> parallel port adapter
(like http://www.amazon.de/Parallel-Centronics-Adapter-Druckerkabel-36pol/dp/B002CP8U3U )
and connect some of the data pins to the FPGA. A simple print in matlab to
the proper PRN port should be sufficient.

Hallo Guys,

thanks alot for your contributions. I have done abit of research and i hav
the following information available:

I will be using a Virtex-5 lx50 Evaluation board, with USB controller fro
Cypress.

My understanding is that the old parallel printer port is a 5V
signalling standard and apply this to a modern FPGA will result in
damage.
