Open Source C Debuggers

The "Open On-Chip Debugger" provides JTAG/SWD access from GDB (or directly with TCL scripts) to processors with ARM and MIPS based cores. See website for full list of supported targets.

gpsim is an open sourced simulator for Microchip's PIC microcontrollers. It supports all three families of PICs: 12-bit, 14-bit, and 16-bit cores. See also gputils http://gputils.sourceforge.net/

A gdb-like debugger for bash

This emulator is capable of providing a faithful replication of the HP48. It also has a debugger for the saturn processor.

TilEm is an emulator for the Z80 series of Texas Instruments graphing calculators. It supports all of the existing models in this series (TI-73, TI-76.fr, TI-81, TI-82, TI-83, TI-83 Plus, TI-84 Plus, TI-85, and TI-86.) TilEm features detailed emulation of all aspects of the calculator hardware, and includes a debugger for writing assembly programs.

HT is a file editor/viewer/analyzer for executables. The goal is to combine the low-level functionality of a debugger and the usability of IDEs. We plan to implement all (hex-)editing features and support of the most important file formats.

Udis86 is an easy-to-use minimalistic disassembler library for the x86 and x86-64 instruction set architectures. The primary intent of the design and development of udis86 is to aid software development projects that entail binary code analysis.

Virtual T is a TRS-80 Model 100/102/200 emulator that runs on Windows, Linux, and Macintosh. The goal of Virtual T is to provide 100% hardware emulation so any existing programs will run. It also adds powerful development and debugging tools.

serialconsole (sc) is a minimal terminal program allowing to use one machine to access the serial console of another machine.

Portable emulator for Pokémon-Mini. Last version: 0.60 (16 June 2015) Check Wiki for platform dependencies and other information.

pwru is an eBPF-based tool for tracing network packets in the Linux kernel with advanced filtering capabilities. It allows fine-grained introspection of kernel state to facilitate debugging network connectivity issues.

Libinstrument is a complete and easy way to do custom function instrumentation for C/C++. The project comes ready with classic applications of instrumentation, such as AOP (Aspect Oriented Programming), Concern and Side Effect injection, stack tracing, exception tracing, basic time profiling, callgraph profiling and other. A GC (Garbage Collector) module is also under development. Libinstrument is highly portable and decoupled. The project comes with a CMake build system, integration with IDEs (CLion, Eclipse e.t.c) is straightforward. Using lazy algorithms there is virtually zero overhead in benchmarks and minimum overhead in execution time. Libinstrument tries to be as non-intrusive as possible, while trying to help the developer offering basic reflection. There are Unit Tests for each class and method, testing is driven with CTest.

Tiny8051 is small 8051 microcontroller simulator written in C#. Project was created for educational purposes, to show how µP works by using clean visual interface and debugging. Note: communication over serial port was not implemented, because there was no demand for it.

GXemul is a full-system computer emulator, emulating processors (ARM, MIPS, M88K, PowerPC, and SuperH) and surrounding peripherals, in some cases well enough to let unmodified guest operating systems run as if they were running on real hardware.

SkyEye is a very fast full system simulator which takes llvm as IR of dynmic compiled framework.. It can simulate series ARM, Coldfire,Mips, Powerpc, Sparc, x86, TI DSP and Blackfin DSP Processor. Also can simulate multicore system by the multicore of host. The commercial support is provided by DigiProto Co. (http://www.digiproto.com)

CTrace is a multi-threaded trace debug library written in C. It provides a simple, fast, well documented trace utility for applications and as such is especially suitable for use in real-time embedded applications.

This is a simulator for the SMIS research MRI consoles. It executes compiled pulse sequences, and emulates the MR3040/50, MR3031, and RF cards. If you have an SMIS scanner, you will find this a useful pulse sequence development aid.

Serial line sniffer (slsnif). slsnif is a serial port logging utility. It listens to the specified serial port and logs all data going through this port in both directions.

A Zilog Z80 simulator, debugger and profiler tailored for ZX Spectrum development (but generic enough to be used with other platforms)

A retargettable micro-controller and embedded system emulator architecture, providing common supports to emulate various types of micro-processors & devices on an x86 PC. Development of emulation for Arduino and various shields is just about to be launched in 2012.

The goal of this project is to develop the OS-independent, obtrusive, customizable, extensible, generic logging and tracing software mechanism.

An in-application debug probe for ARM Cortex-M microcontrollers. Source code and bug tracker can be found at https://github.com/blacksphere/blackmagic

Cinemagoer is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. Platform-independent, it can retrieve data from both the IMDb's web server and a local copy of the whole db.

This project contains some test scripts and software for Analog Devices' DSP chip emulators. This verifies whether a particular emulator is working correctly with a particular PC and target board.
