Horizon is an EDA package supporting an integrated end-to-end workflow for PCB design, including from parts management and schematic entry to gerber export.

The Amaranth project provides an open-source toolchain for developing hardware based on synchronous digital logic using the Python programming language, as well as evaluation board definitions and a System on Chip toolkit.

This is a pythonized, kind of reverse engineered version of original AACircuit written by Andreas Weber in Borland Delphi. The idea and GUI layout are also taken from the original.

ABC is a program for sequential logic synthesis and formal verification.

Mcy is an EDA tool to help digital designers and project managers understand and improve testbench coverage.

UHDM is a complete modeling of the IEEE SystemVerilog Object Model with VPI Interface, Elaborator, Serialization, Visitor and Listener.

OpenBoardView is a viewer for BoardView files, which present the details of a printed circuit board (PCB). It comes with features such as:

• Dynamic part outline rendering, including complex connectors

• Annotations, for leaving notes about parts, nets, pins or location

• Configurable colour themes

• Configurable DPI to facilitate usage on 4K monitors

• Configurable for running on slower systems

• Reads FZ (with key), BRD, BRD2, BDV and BV* formats.

Surfer is a waveform viewer used in EDA with a focus on usability and extensibility.

This package provides CERN's KiCad component libraries, including schematic symbols, footprints, a SQLite-backed database library, and KiCad library tables. The libraries are generated from CERN's Altium Designer libraries.

This package contains the official KiCad 3D model libraries.

Charlib is an EDA tool used to extract timing and power characteristics from CMOS combinational and sequential standard-cells. It is compatible with ngspice and Xyce.

Qucsator-rf is a command line driven circuit simulator targeted for RF and microwave circuits. It takes a network list in a certain format as input and outputs an XML dataset.

GNUcap is a circuit analysis package used for EDA. It offers a general purpose circuit simulator and can perform DC and transient analyses, fourier analysis and AC analysis. The engine is designed to do true mixed-mode simulation.

Cocotb-bus provides a set of utilities, test benches and reusable bus interfaces to be used with cocotb.

VSG lets you define a VHDL coding style and provides a command-line tool to enforce it.

The Dirtywave M8 Tracker is a portable sequencer and synthesizer, featuring 8 tracks of assignable instruments such as FM, waveform synthesis, virtual analog, sample playback, and MIDI output. It is powered by a Teensy micro-controller and inspired by the Gameboy tracker Little Sound DJ. m8c is a client for M8 Headless which allows one to install the M8 firmware on any Teensy.

This package provides a library to turn Python into a hardware description and verification language.

Libsigrokdecode is a shared library written in C, which provides (streaming) protocol decoding functionality.

A minimal application for the qcsxcad library which is used to describe geometrical objects and their physical and non-physical properties.

lln-libparse is a SWIG-based Python wrapper around Yosys' libparse, enabling dotlib file parsing.

Gerbv is a viewer for files in the Gerber format (RS-274X only), which is commonly used to represent printed circuit board (PCB) layouts. Gerbv lets you load several files on top of each other, do measurements on the displayed image, etc. Besides viewing Gerbers, you may also view Excellon drill files as well as pick-place files.

Library for describing geometrical objects and their physical and non-physical properties.

qrouter is an ASICs tool intended for digital chip design. It creates the detailed routes for layouts of digital circuits and generates metal layers and vias.
