FTDI FT60x USB3.0 to AXI bus master

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.

Performance

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).
