README
README.mdWIP! WIP! WIP!
This repo is a work in progress and far from release-worthy. Please don't make your own boards and expect any kind of support. However, it might reach a stable point sometime in the future (as of 2019-01).
Kilsyth: ECP5 FPGA + FT60x FIFO
Kilsyth is a piece of hardware that contains an FPGA (Lattice ECP5) and a SuperSpeed USB 3.0 FIFO-bridge (FT60x). The goal is to provide a platform to be able to transfer high speed data transfers between a PC and an FPGA. The FPGA in turn can do whatever - e.g. interface with SDR, video capture, act as a logic analyzer.
Current status
It's still in the early bring-up phase. Initial verification shows that it actually seems to work.
RevA
RevA is the first prototype and has been designed and built.
- It doesn't smoke when powered up.
- USB-C connector works but is messy to solder.
- Loopback test is almost in place. Using the proprietary driver, high bi-directional speeds are achieavable (> 98MB/s in both directions simultaneously). Just need to figure out some off-by-one errors...
- Bootloader to store a custom bitstream on the flash.
Errata:
- C9 is not a GPIO on ECP5 F12 and some other variants. To get the LED working put a jumper on pin 31 and 33 on the Wide connector.
- FT_CLK is not routed to a clock pin. Can be fixed with a bodge wire! Remove R50 and R36, swap their paths.
- JTAG connector has a funky footprint on the PCB because CCW vs Odd/Even pinout on the symbol vs footprint. But the PCB silk screen is accurate so don't worry - it's just a stupid pinout.
- Need to add pull-ups for the SPI flash.
RevB
Ideas for RevB are still being collected. Feel free to suggest changes in an issue.
- Add support for reversible USB-C connector using PI5USB30213A.
Software usage (TODO)
Requires a patched migen and a patched ftdi library.. Nasty, I know, sorry.

Questions
How big is the Kilsyth PCB?
It measures 95 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Kilsyth use?
170 parts, built around the LFE5U-85F-6BG381C, FT600Q-B-T, IS25LP128F-JBLE and TPS65261RHB. 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 Kilsyth KiCad files?
From the kbeckmann/Kilsyth repository on GitHub, at the commit this page was made from: the board is hardware/RevA/Kilsyth.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kilsyth design in my own project?
Its repository publishes it under the 0BSD licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
