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

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.

Nextpnr is a portable FPGA place and route tool.

Sch-rnd is a standalone and workflow agnostic schematics capture tool for PCB, part of the RiNgDove EDA suite.

OpenSTA is a gate level static timing verifier. As a stand-alone executable it can be used to verify the timing of a design using standard file formats.

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.

This package implements a functionality to create project files for supported tools and run them in batch or GUI mode. All EDA tools such as Icarus, Yosys, ModelSim, Vivado, Verilator, GHDL, Quartus etc get input HDL files (Verilog and VHDL) and some tool-specific files (constraint files,memory initialization files, IP description files etc). Together with the files, perhaps a couple of Verilog `defines, some top-level parameters/generics or some tool-specific options are set.

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.

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

Prjpeppercorn includes programming tools for GateMate architecture from Cologne Chip. It also provides data needed to produce a nextpnr chip database Cologne Chip's GateMate architecture.

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

Nextpnr is a portable FPGA place and route tool.

The JSON-for-VHDL library provides a parser to query JSON data structures from external files on disk. It provides a context to be used in the declarative section of design units.

libsigrok is a shared library written in C which provides the basic hardware access drivers for logic analyzers and other supported devices, as well as input/output file format support.

Verilator transforms the specified Verilog or SystemVerilog code by reading it, performing lint checks, and optionally inserting assertion checks and coverage-analysis points. It outputs single- or multi-threaded .cpp and .h files.

Sigrok-cli is a command-line frontend for sigrok.

This package provides a VHDL compiler and simulator.

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.

Open source materials intended for reference by the IEEE standard 1076, as approved and published by the VHDL Analysis and Standardization Group.

libdwarf is a library that handles the DWARF debugging information format.

chrpath allows listing, changing or removing the dynamic library load path (RPATH and RUNPATH) of compiled programs and libraries.

Libelf is a C library to access ELF object files.

Elfutils is a collection of utilities and libraries to read, create and modify Executable and Linkable Format (ELF) binary files, find and handle Debugging With Arbitrary Record Formats (DWARF) debug data, symbols, thread state and stacktraces for processes and core files on GNU/Linux. Elfutils includes libelf for manipulating ELF files, libdw for inspecting DWARF data and process state and utilities like eu-stack (to show backtraces), eu-nm (for listing symbols from object files), eu-size (for listing the section sizes of an object or archive file), eu-strip (for discarding symbols), eu-readelf (to see the raw ELF file structures), eu-elflint (to check for well-formed ELF files), eu-elfcompress (to compress or decompress ELF sections), and more.
