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/

LibrePCB is a free, cross-platform, easy-to-use electronic design automation suite to draw schematics and design printed circuit boards – for makers, students, and professionals, from beginners to experts. LibrePCB is developed with portability in mind to make it run on virtually any computer – including Windows, Linux, and macOS. It’s available in 22 different languages, and it doesn’t cost any money. Simple, intuitive, well-known user-interface concepts help to get started with LibrePCB very quickly. No need to study the documentation for days – just start working on it. A LibrePCB library is more than just a collection of stupid graphics for symbols and footprints – they are organized in a meaningful, semantic manner. This makes library management more fun and eliminates many problems known from other EDA tools.

A Binary Decision Diagram library, with : many highly efficient vectorized BDD operations, dynamic variable reordering, automated garbage collection, a C++ interface with automatic reference counting, and much more.

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.

Sparse is a direct method solver for the large sparse matrices that are associated with electrical circuit simulation. It uses LU factorization and handles both real and complex square matrices.It is intended to solve many matrices with the same structure

Eclipse Verilog editor is a plugin for the Eclipse IDE. It provides Verilog(IEEE-1364) and VHDL language specific code viewer, contents outline, code assist etc. It helps coding and debugging in hardware development based on Verilog or VHDL.
