PICSimLab is a realtime emulator of development boards with MPLABX/avr-gdb debugger integration. PICSimLab supports microcontrollers from picsim, simavr, uCsim, qemu-stm32, qemu-esp32, and gpsim. PICSimLab has integration with MPLABX/Arduino IDE for programming the microcontroller's boards. As the purpose of PICSimLab is to emulate real hardware it does not have any source code editing support. For code editing and debugging the same tools used for a real board should be used with PICSimLab, such as MPLABX, Arduino IDE, or VSCode with PlatformIO. PICSimLab supports several devices (spare parts) that can be connected to the boards for simulation. Such as example LEDs and push buttons for simple outputs and inputs and some more complex ones like the ethernet shield w5500 for internet connection or the color graphic display ili9340 with touchscreen. The complete list of parts can be accessed in the documentation. Documentation at https://lcgamboa.github.io/picsimlab_docs/stable/

Gerber2PDF is a command-line tool to convert Gerber files to PDF for proofing and hobbyist printing purposes. It converts multiple Gerber files at once, placing the resulting layers each on it's own page within the PDF. Each layer has a PDF bookmark for easy reference. Layers can optionally be combined onto a single page and rendered with custom colours and transparency. There is a Drill to Gerber converter available from the downloads page.

GNU SPICE GUI provides a GUI front-end for various freely available electronic circuit simulation engines ie. NG-SPICE and GNU-CAP. It's core function is to generate simulation engine instructions based on user input. However, it also offers extra functionality via applications and utilities developed by others. Electronic Design Automation (EDA) tool suites are used to provide schematic capture and editing, and schematic to netlist conversion. Waveform data viewers are used to display simulation results and PDF viewers to display user manuals.

Cross-platform software for producing Veroboard (stripboard), Perfboard, and 1-layer or 2-layer PCB layouts. Automatically prevents short-circuits and checks for open-circuits. Pre-compiled versions available for MS Windows and 64-bit Linux Mint 20.3 (should also run on other 64-bit Linux systems that are based on Debian and support Qt version >= 5.12.8). Android APK available (tested on Android 7 and Android 10) and requires device resolution of at least 1280x800.

EAVREF is a computer-aided tool for robustly designing ultra-low-power CMOS voltage references. The tool is compatible with the powerful Ngspice simulator, enabling open-source microelectronics design flow with SkyWater 130nm Technology.

VTracer is a Verilog Testbench developer aid. Contains well documented Verilog-Perl co-simulation environment (TCP sockets based), structural Verilog parser, demo Testbenches.

NetworkDesigner does the design of various impedance matching networks. The designs are useful for both solid state designs as well as vacuum tube/valve circuits. In the newest version, the filter design functionality has been split off and will appear as a separate app. This makes for a cleaner user interface, The latest version was made from the FOX toolkit, and it is included in the package. This is the latest stable version of FOX.

Turns-n-Layers is a command line transformer and induction coil design aid that calculates the amount of wire needed, both length (feet) and weight (lbs). Also, the finished dimensions of the coil and the resistance are also returned.

FXtransformer Designer is a graphical design aid for both power and RF transformers. RF Design: Broadband, Single-Tuned, Double-Tuned.

gputils is a collection of tools for Microchip PIC microcontrollers. Its goal is to be fully compatible with Microchip's tools, MPASM, MPLINK, and MPLIB.

PCB is a tool for the layout of printed circuit boards. PCB can produce industry standard RS-274X and Excellon NC-Drill format output for submission to board manufacturers.

DLD V 2.0 Released Digital Logic Design is a Software tool for designing and simulating digital circuits. It provides digital parts ranging from simple gates to Arithmetic Logic Unit. You may start your circuit from simple gates and flipflops and keep on converting them into ICs. These ICs, later on, may be incorporated into other circuits to built more complex circuits like CPU. You may even use SOP expressions to generate digital circuits in IC form. You can use this software to design Combinational, Synchronous and Asynchronous Sequential Circuits. The circuit working can be analyzed by using output parts like LEDs, Seven Segment Display as well as CRT and digital Oscilloscope all provided in the software. This Software may be used by professionals, hobbyists and students alike. The teachers may incorporate this software in their courses like Digital Logic and Computer Design, Computer Architecture, Computer Organization and Embedded Systems.

UMHDL is an educational Integrated Development Environment (IDE) intended for learning digital designing with programmable logic devices using Hardware Description Languages (HDL) through simulation. It is an open-source application created at the Miguel Hernández University (UMH). The aim for the UMHDL development was to have a graphical application that allows learning the VHDL language without licensing restrictions (using some existing open-source tools) and requiring few resources. So, the interface developed acts as a front-end that allows writing code (with syntax highlighting), invokes an external VHDL compiler and simulator (such as GHDL), and displays the result of the simulation graphically as waveforms (invoking to GTKWave).

Verilator converts synthesizable Verilog HDL modules into SystemC modules. This enables users with Verilog code to have a publicly available co-simulation environment. For all information, see http://www.veripool.com/verilator.html.

Java Quine McCluskey implements the Quine McCluskey algorithm with Petrick’s Method (or the method of prime implicants) for minimization of Boolean functions. This software can be used both for learning and solving real problems. As a learning/teaching tool, it presents not only the results but also how the problem was solved as well as how to use Karnaugh Maps to solve the problem. Up to sixteen functions of sixteen variables can be minimized. A graphical interface is provided for entering and editing the truth table that can be saved and loaded. The results can be exported in HTML format. It generates the Karnaugh Map for educational purposes and the actual truth table from the obtained expressions even when multiple solutions for each function are found. This implementation supports PLC programming, so results can be presented in many forms including Structured Text (ST) and Ladder Diagram (LD) along with conventional Boolean expression.
