FTDI FT601 SuperSpeed USB3.0 to AXI bus master

Github: https://github.com/ultraembedded/core_ft60x_axi

This component allows an FTDI FT601 USB3.0 device to act as a high-performance AXI4 bus master.

Features
  • Interfaces to FTDI FT601 USB FIFO device.
  • AXI-4 bus master with support for incrementing bursts and multiple outstanding transactions (for high performance).
  • 2 x 8KB FIFO (which map to BlockRAMs in Xilinx FPGAs).
  • Designed to work @ 100MHz in FPGA (as per FTDI FT60x max clock rate).
  • Uses FT60x 245 mode protocol (32-bit mode).
  • Support for 32 GPIO.
  • Capable of sustained pipelined AXI-4 burst reads @ 170MB/s and writes @ 230MB/s.

Testing

Verified under simulation (constrained random testing), and tested on a Xilinx Artix 7 with blockRAM and DDR3 targets on the LambdaConcept USB2Sniffer Board (connected to a Linux host PC).

Test setup;

  • LambdaConcept USB2Sniffer Board
  • Linux Distro: Linux Mint 19 Tara
  • Linux Kernel 5.4.0-050400rc5
  • Intel Corporation JHL7540 Thunderbolt 3 USB Controller [Titan Ridge 4C 2018]

Uses the FTDI D3XX drivers which are available for Linux, OS-X, and Windows (although this has only been tested under Linux currently).
