About the Tedium X8 PCB

Tedium X8 is an open source FPGA PCB design by jboone, published on GitHub under the BSD-3-Clause license. It is a 4-layer board measuring 96 × 70 mm, with 279 components from 74 distinct parts.

Its main chip is the LFE5U-85F-8BG381, from the FPGA family. Other key parts include the TPS53318, TPS62823, XRT86VX38, ADM7171ACPZ-3.3-R7 and ADP150AUJZ-2.5-R7. By type, the board carries 138 capacitors, 78 resistors, 18 ICs, 16 test points, 11 inductors and 6 connectors.

It belongs with the usb & debug tools designs in this gallery.

From the project

TDM telephony experimentation

oss-cad-suite: open-source digital design and verification tools, with nightly binary builds. poetry: Python dependencies and packaging management tool. g++-riscv64-linux-gnu rustup toolchain install stable -t riscv32i-unknown-none-elf

Clone this repository, and generally follow these steps:

NOTE: My Tedium .venv got weird when I had the "OSS CAD Suite" environment already enabled. Poetry would download dependencies on poetry install or poetry update, but would then delete them when running poetry run or poetry shell.

Tedium X8: common questions

What microcontroller does the Tedium X8 use?

The Tedium X8 is built around the LFE5U-85F-8BG381, from the FPGA family.

How big is the Tedium X8 PCB?

The Tedium X8 measures 96 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Tedium X8?

279 components, from 74 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tedium X8 design files?

From the jboone/tedium repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Tedium X8 design in my own project?

Yes, under the terms of its BSD-3-Clause license, which jboone chose for the repository.

Can I test firmware for the Tedium X8 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
