Surelog is a pre-processor, parser, elaborator and UHDM compiler. It provides IEEE design, a C/C++ VPI and a Python AST API.

Xyce is a SPICE-compatible, high-performance analog circuit simulator, capable of solving extremely large circuit problems by supporting large-scale parallel computing platforms. It also supports serial execution.

fftgen produces FFT hardware designs in Verilog.

PyRTL provides a collection of classes for Pythonic RTL-level design, simulation, tracing, and testing, suitable for teaching and research.

PySpice implements a Ngspice binding and provides an oriented object API on top of SPICE, the simulation output is converted to Numpy arrays for convenience.

Ngspice is a mixed-level/mixed-signal circuit simulator. It includes Spice3f5, a circuit simulator, and Xspice, an extension that provides code modeling support and simulation of digital components through an embedded event driven algorithm.

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

Eqy is an EDA front-end driver program for Yosys-based formal hardware equivalence checking. It performs formal verification on two designs, such as ensuring that a synthesis tool has not introduced functional changes into a design, or ensuring that a design refactor preserves correctness in all conditions.

This package is a waveform viewer for FST files.

qucsrflayout command exports RF schematics to KiCad layouts and OpenEMS scripts.

Ngspice is a mixed-level/mixed-signal circuit simulator. It includes Spice3f5, a circuit simulator, and Xspice, an extension that provides code modeling support and simulation of digital components through an embedded event driven algorithm.

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.

Pydigitalwavetools is a Python library to parse, write and format digital wave files in VCD format, a standardized ASCII format used to store simulation data from Verilog and other hardware description languages.

gdstk is a library for creation and manipulation of GDSII layout files which are commonly used for EDA and chip design.

Hdlmake helps manage and share HDL code by automatically finding file dependencies, writing synthesis and simulation Makefiles.

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.

Xoscope is a digital oscilloscope that can acquire signals from ALSA, ESD, and COMEDI sources. This package currently does not include support for ESD or COMEDI sources.

nextpnr is an EDA, portable and vendor neutral FPGA place and route tool.

ciel downloads and installs open-source PDKs which are used for chip design and EDA.

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.

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

This package provides a VHDL compiler and simulator.

nextpnr is an EDA, portable and vendor neutral FPGA place and route tool.

lctime extracts timing and power characteristics of CMOS standard-cells. It simulates the netlists of the cells with ngspice and writes the characterization result in a liberty library file.
