Open source Artix-7 FPGA designed to be used with PCILeech.
For schematic/layout/assembly/pcb diagrams, please see the outputs folder.
Overview
Initial design was based on a combination of the LambdaConcept PCIe Screamer Squirrel and the Enigma-X1 LeetDMA.
PCIexpress layout is based on lucanastasio/PCIexpress-KiCad PCIexpress_x4_low.
Initially will try to keep the board as a 6-layer PCB using the JLC3313 6-Layer Impedance Control Stackup, layer stackup plan would be Signal/Ground/Power/Power/Ground/Signal, with the outside signal layers also having a ground pour. PCIe and USB3 SS traces would be impedance matched (and length matched as necessary) on top and bottom layers as coplanar waveguides for each pair.
There are two on-board USB-C ports, one for JTAG debugging/programming of the FPGA/flash, the other as a usb superspeed link for DMA access. The board is also designed such that it can be powered and programmed/tested from the JTAG USB connector, without needing to be plugged into a PCIe slot.
Progress
From a high level perspective, the board is largely complete. It does, however, need to be checked before first batch ordered. The following is a rough list of what needs to be reviewed, and any input is welcome from knowledgeable parties.
-
Schematic Review
- Part Selection
- BOM Check
- Connectivity
-
PCB Review
- Placement
- Footprints
- Routing
- Impedance
Once board is finalised, the software side needs to be started integrating with PCILeech. Specifically, PCILeech FPGA

Questions
How big is the PCIeDMA PCB?
It measures 79.3 × 68.9 mm and has 6 copper layers, 1.56 mm thick.
What parts does the PCIeDMA use?
267 parts, built around the MT2492, CH347T, FT601Q-B-T and EA3059QDR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PCIeDMA KiCad files?
From the jayhusemi/PCIeDMA repository on GitHub, at the commit this page was made from: the board is PCIeDMA.kicad_pcb and its schematic FPGA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCIeDMA design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
