HELLO,PLEASE GIVE SOME ADVISE,
I AM DESIGNING MY FPGA BORAD ,AND I WANT TO MAKE COMMUNICATION WITH PC THROUGH USB.I WANT TO KNOW HOW I CAN DO THAT,INCLUDING HARDWARE AND SOFTWARE,OR INTREDUCE ANY BOOKS FOR ME .
THANKS A LOT.
NICE DAY.
 

HELP WITH USB??

Depending on your FPGA board, it maybe easiest to use a USB to Serial converter and implement a RS232 protocol on your FPGA which is much easier than anything else. You can go up to 1MBits/second on the latest version of those converters that is good enough for a lot of projects.

THX，In fact ,I am trying to use usb2.0 to connect to pc.I have used the use-rs232 already to send datas.
 

The easiest option since, you have already successfully implemented a UART core, is to use a chip such as the following:

FTDI USB Slave Converters

If you want to implement a true USB interface, you'll need a USB transceiver inconjunction with a USB controller core implemented in the FPGA:

There are a multitude of USB transceiver available, one example is:

Cypress TX2UL USB 2.0 Transceiver

Of course your FPGA will determine a compatible chip, voltage levels, etc.

An Open Source USB Core can be found at:

OpenCores Projects

Look under Communication Cores.

Hope these links and info help with your endeavor.
