Generating files from FPGA to hard drive

Hi guys. I'm working on a VHDL project for university and I'd like to know how could I generate a file from FPGA to the hard drive of the computer through the USB cable. I mean, it seems to me that i...

All you need to do is implement a UART core - its a qsys module - 2 wires (RX and TX), fixed baud rate.

To interface with USB, buy a UART to USB converter - it cost $5 or less.

Then use the NIOS on any FPGA to write data to your UART module, it will send that data to the TX pin serially, and the UART to USB converter will deliver it to the PC.

Sending data to the PC from the FPGA is a fairly simple task
