Open Source C Simulation Software

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/

A free cross-platform library of fast C++ routines for the plotting of up to 3-ranged data. It can export to bitmap and vector EPS/SVG files. There are window interfaces (GLUT/FLTK/Qt) and console tools. MathGL can be used from C/Fortran/Python/Octav/Lua

Netkit is a network emulation environment that allows the user to set up complex scenarios on a single PC with little effort and at no cost. In itself, Netkit aims at integrating different other open source products to provide an easy-to-use interface.

The Virtual Motherboard provides a specification of a TCP/IP based system bus, a motherboard simulator implementing this specifaction, and a collection of reusable device simulators. It is the perfect start to build new custom hardware simulators.

Artist is a portable 2D graphics library. Main features are: drawing primitives, bitmap blitting, alpha blending, zoom and rotation, text rendering and image file loading. It uses hardware acceleration and provides a simple and elegent API.

A text-mode simulator for the original 12-bit, 4K core memory PDP-8 desktop computer.

Calculates how much time and money you need to win in the lottery. It uses multiple gthreads and gtk2 to sort 1 to 50 numbers until the user wins. Asking for the cost and time beetwin games, it calculates if you or your grandchildren will be rich.

ComLinC (a COMmunications Library IN C programming language), a C library for communications research and simulation. It's based on GSL. ComLinC aims at providing elegent, fast functionality to the frequently encountered problems in communications area.

DSPemu emule a digital signal processor TMS320F243, with console interface showing the registers and memory. With DSPemu is possible test algorithms such as Filter, FFT/IFFT. This can be integrate and used with a circuit simulator.

This project introduces a kernel module "dnburstyloss" to enable dummynet emulate bursty packet loss by integrating some common theoretical loss models into Dummynet.

The main purpose of this project is to develop the control software of the digital three phase soft-starter which allows the user to start and stop the motor in an effective way.

Major looseless compression algorithms library and documentation. First project: Arithmetic, Huffman, LZ77, LZ78, LZW, RLE. Second project reimplements Deflate. Documentation explains major Entropy Compression Methods.

Simulator for Siemens S7-200 PLC. It supports boolean operations, counters, timers, rise up and fall down contacts, and mathematics operations, with integer and real numbers, like sin, cos, tan. Comments and advise are well accepted!

Create phyiscal simulations easily through IPSA which combines the OpenInventor 3D API with the Open Dynamics Engine (ODE). Scenes are read from .iv files and simulated in the supplied viewer applications. Find it at: http://ipsa.sourceforge.net

Laboratory Circuit Simulator is transient simulator whiht analog and digital components support for laboratory classes. This support spice netlist files, DSP Tms320f243 DSPemu integration and has high customizable device modules development in c.

LSim is a software for simulation and make executables to ARM Cortex-M3 mcu from logic gates diagram. LSim can compile logic gates diagram and generate binary executable files (*.bin, *.hex) for cortex-m3 mcu´s (LPC1768, under development).

MBDyn_sim_suite is a collection of free pre&post-processing tools and simulation models for the open-source multi-body analysis software MBDyn forming a general purpose simulation environment for structural dynamics with an emphasis on wind turbines.

MORSEL is a simple microprocessor simulator designed for use as a temporary aid for teaching children to program.

The goal of this project is to extend an existing IDE (KDevelop) with support for compiling, debugging and executing of parallel MPI programs ( see http://www-unix.mcs.anl.gov/mpi ) . Current plugin version runs under Linux on KDE 3.3 with KDevelop 3.1.1

Neural Network class library: Its a C/C++ implementation that provides following three neural architecture - Feed-forward network, Radial Basis function network, multi-layer perceptron and Self-Organizing Maps.

- - - T H I S P R O J E C T M O V E D T O G I T H U B - - - A framework for the implementation of advanced real-time control systems which uses signal/block-based schematics (like Simulink) extended by several features like state machines and online-exchangeable sub-simulations. Besides, this framework properly handles multiple threads, their communication, allows to synchronise control systems to external events (e.g. variable timers or incoming network packages) and provides many other nice features. Because of a high-level schematic-description language -- in form of provided Scilab commands -- only a minimal implementation-effort (no error-prone C-programming) is required.

PIHMgis is a “tightly-coupled” GIS interface to Penn State Integrated Hydrologic Model (PIHM). It is open source, platform independent and extensible. The “tightly-coupled” integrated GIS interface to PIHM has been created in the Open Source QGIS
