USB code, written in VHDL

[Michiel]

Hello,

I 'm a student who is working with a FPGA (Virtex II pro) and I would
like to include USB. Does anyone know of any USB code, written in VHDL,
that is available on the web?

Regards,

Michiel

 

Can you explain a little more ?
What do you mean with "include USB" ?

I want to make a USB port on the FPGA so I can communicate with other
devices using USB.

 

First I recommend to read the USB2.0 specification.
(www.usb.org)

What are you going to do? Do you want to play the role
of an USB Host ? Or are you receiving data from Host ?

Please be more clear.

Both, being the USB Host or the Device requires handling good amount of
special data structures in hardware to be able to communicate with the
host processor as per the standard. I doubt anyone would give such a
design for free.

Have a look at external USB transceiver devices. The interface towards
the FPGA become easier then.

Tanks for all the tips you gave me
I think I will use an external USB transceiver => my professor gave me
one
