Interfacing a circuit in an FPGA to a PC

If you have an interest in exchanging data between circuitry in an FPGA and= a PC, I have written a simple GUI that demonstrates transfers at full USB2= rates to and from an FPGA interfaced with an FTDI FT2232H USB2 interface c= hip (i.e. the FTDI Morph-IC-II).

There is a free (binary only) download :=20

, or source code is available for both personal and commercial uses : i.e. (Altera Quartus II v11.1sp2 archive) plus script source plus GUI binary or= source.

There is a help page at :

ace_to_PC/help.html and a YouTube video putting this code through its paces at :

These demonstrate a fast way of getting PC access to firmware circuitry in = a Field Programmable Gate Array (FPGA). Pre-written VHDL firmware and array-based software facilitate interfacing a= PC to the FPGA over the USB, and gives transparent access to multiple bank= s of sub-modules and instrument functions in the FPGA at full USB2 rates of= 480 Mbit/s (60 MBytes/s).

Each sub-module has an independent block of up to 256 USB interface registe= rs, to configure the sub-instrument and for bi-directional data transfer. T= his Lab-Tools code forms the skeleton into which the sub-modules / instrume= nts may be slotted, in a consistent manner.
