A year's worth of work and headache. Being stuck 95% of the time. Finally the first square wave coming out of the Kintex7 GTX transceiver, using #openXC7 the full open source FPGA toolchain.

Announcing first useable release of LiteUSB, a native USB2 highspeed device core for the LiteX/migen ecosystem. It can do something like serving the serial console of a LiteX SoC over USB acm serial, but also very fancy devices like an USB2 HS audio interface work.

Only 9 unidentified bits keep the GTX transceivers from working. The bits are known, but what they do isn't yet.

This migen/LiteX design transforms your Terasic DECA board into a full fledged high speed USB2 audio interface. It is based on LiteUSB, my recent LiteX port of LUNA, an open source USB2 device core.

Want to play with the Zynq hard processor system with a full open source toolchain? You can!
Many thanks @regymm0 for implementing Zynq HPS support for the openXC7 open source FPGA toolchain,
and for providing this demo:

Wait, only the first one, actually

Leonardo Romor's fpga-assembler is now integrated into the openXC7 opensource FPGA toolchain (nix version). snap version in the next release
https://github.com/openXC7/toolchain-nix/
Leonardo Romor wrote a C implementation of the python fasm (FPGA assembler), which he says is up to 10x faster than the python implementation.
This will be an exciting addition to the openXC7 open source FPGA toolchain!
