XSCHEM
Schematic circuit editor for VLSI and Mixed mode circuit simulation.
Xschem is a schematic capture program, it allows to create a hierarchical representation of circuits with a top down approach . By focusing on interconnections, hierarchy and properties a complex system (IC) can be described in terms of simpler building blocks. A VHDL, Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this gives top speed performance, even on very big circuits. I have succesfully managed to simulate complete VLSI projects with this tool, both digital (Verilog / VHDL) and analog (Spice). Schematics can be printed in SVG, PNG, PDF, formats. XSCHEM runs on Linux or other Unix-likes with Xorg server and on Windows with the Cygwin layer and required tools installed. Can be found also on github: https://github.com/StefanSchippers/xschem -

rw
rw calculates rank-width and rank-decompositions.
rw calculates rank-width and rank-decompositions. It is based on ideas from "Computing rank-width exactly" by Sang-il Oum, "Sopra una formula numerica" by Ernesto Pascal, "Generation of a Vector from the Lexicographical Index" by B.P. Buckles and M. Lybanon and "Fast additions on masked integers" by Michael D. Adams and David S. Wise. On 2009's computers it works quite well up to graph sizes of about 28 nodes. Runtime and memory usage are exponential in the graph size. -

EQ10Q
Audio plugin bundle over the LV2 standard for Linux
EQ10Q is an audio plugin bundle over the LV2 standard implementing a powerful and flexible parametric equalizer and more, take a look in “Included Plugins” in our website (http://eq10q.sourceforge.net/?page_id=96) to get a complete idea of what is EQ10Q about. All audio processing developed in this project is written in C language and highly optimized focusing on DSP load reduction yet keeping a superb audio quality, the audio engine is always working in 64 bits floating point maths but interfacing with LV2 ports using the standard 32 bits numbers. We believe that a good plugin is not completely useful without a full featured graphical user interface (GUI) that provides the correct way to set it up. For this reason, each plugin distributed in this bundle is supplied with a nice GUI. These GUI’s are written in C++ and Gtkmm libraries to gain a great control over the graphics. -

GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.

American Fuzzy Lop
American fuzzy lop - a security-oriented fuzzer
AFL (American Fuzzy Lop) is a widely used graybox fuzzer that discovers bugs by mutating inputs and steering execution using lightweight instrumentation. Instead of random mutations alone, it uses coverage feedback to evolve input corpora, pushing programs into deeper and more interesting code paths. Its workflow emphasizes quick start: point it at a target binary with compile-time instrumentation (or use QEMU-based mode when recompilation isn’t possible), seed it with a small corpus, and let it iterate. AFL is known for finding serious security issues in complex software due to its corpus minimization, queue management, and deterministic mutation stages that balance breadth and depth. It provides crash triage helpers and test case minimization so developers can reproduce and fix issues quickly. The design deliberately optimizes for robustness and speed on commodity hardware, which helped it become a standard part of many security testing pipelines. -
