About the Gate to glass PCB

Gate to glass is an open source FPGA PCB design by OoEthanoO, published on GitHub. It is a board, with 49 components from 19 distinct parts.

Its main chip is the ICE40UP5K-SG48ITR, from the FPGA family. Other key parts include the 3.3V, 1.2V, 32MBIT and 12MHZ. By type, the board carries 18 capacitors, 10 resistors, 9 switches, 5 ICs, 4 connectors and 3 diodes.

gtgreva.kicadsch is generated from hw/netlist.csv by tools/gensch.py`. Do not edit it as a source file — regenerate it.

tools/checkhw.py` validates the netlist against the FPGA package, the BOM and the RTL's port list. It cannot check what KiCad checks: that a power input is actually driven, that pin types are compatible, that a symbol's units are all placed. Two checkers with different blind spots beat one careful one.

Gate to glass: common questions

What microcontroller does the Gate to glass use?

The Gate to glass is built around the ICE40UP5K-SG48ITR, from the FPGA family.

How many components are on the Gate to glass?

49 components, from 19 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Gate to glass design files?

From the OoEthanoO/gate-to-glass repository on GitHub, which has the schematic, a netlist and the BOM; the links under Design files point to each one.

Can I use the Gate to glass design in my own project?

The repository has no license, so all rights stay with OoEthanoO. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Gate to glass 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.
