Can an FPGA really push 250 Mbps over USB 2.0?
In this video I turn a Digilent Arty A7 (Artix-7) into a USB 2.0 logic analyzer using an FTDI FT2232H in synchronous FIFO (245) mode, and walk through the full Verilog that makes the link fast and reliable. On camera we see ~135 Mbps (screen-recording overhead); the pipeline is built for 200–250 Mbps with low latency.

What you’ll learn

How FT2232H Sync-FIFO works: 8-bit data, 60 MHz clock, RXF#/TXE#/RD#/WR#/OE# handshakes

Verilog FSMs for TX/RX, bus turn-around timing (falling-edge launches), and back-pressure with a 72-bit FIFO

A simple framed protocol (flags + CRC-8) with a 9-byte payload for robust streaming

Loopback/“constant” test mode and SW / SW-multiple modes used as a multi-channel signal analyzer

How this USB link becomes the data engine for a DIY logic analyzer, oscilloscope, or SDR

Hardware

FT2232H mini-module (FTDI)

Arty A7 / Artix-7 FPGA board

Jumper-wire prototype (final build will move to a PCB)

Code

Verilog sources (TX/RX parsers, FIFO, CRC, control FSMs).
