Eitri
I'm building Eitri as a small, modern VHDL workspace for my school lab assignments.
I wanted to work at home without installing a 30–40 GB Vivado setup full of features I'd never need just to learn VHDL. I couldn't find an alternative that felt both complete enough and modern enough for what I wanted, so I started making my own.
With Eitri, I can write designs and testbenches, reuse components, simulate signals, and see how my code becomes a circuit all in one app. It uses PySide6 for the interface, GHDL for VHDL simulation and synthesis, and Yosys with netlistsvg for circuit diagrams. My focus is learning and experimenting with VHDL, not replacing a complete FPGA implementation toolchain.
A look inside
These screenshots show my 4-bit full adder, built from four 1-bit adders.
Write designs and testbenches
Simulate and inspect waveforms
View component connections or expand them into logic gates
Running Eitri
Install the wheel matching your platform (or, once published, pip install eitri-hdl). Start the application with eitri or:
python -m eitri

Contributing to the app
See docs/CONTRIBUTING.md for a map of the UI modules,
signal flow, and where to add controls or change behavior. Start with
src/eitri/ui/window.py for the overall composition.
