KMD is a multi-processor debugger. It can debug with hardware boards over serial ports or with software emulators (ARM and MIPS emulators are included in the project). Using the pipe option you can debug over the network or any other communication medium. It can load many executable formats such as ELF, and display and follow the original source even from multiple source file programs. There is support for breakpoints and watchpoints which can trap on specific data (such as loading or executing specific instructions). Support for other features such as FPGA's is also available, allowing loading or any control required to drive a specific hardware device. The project uses chump to allow disassembly and line assembly. Chump also allows new architectures to be easily added without the need to recompile the system. Communication with the backend is done using two pipes/fifos using a simple set of codes. Back end communication program can be created using very little memory on the target device.
Avrora is a set of tools for programs that run on the AVR series of microcontrollers produced by Atmel. It contains a flexible framework for simulating, analyzing, and optimizing assembly programs, and provides a clean Java API and infrastructure for experimentation, profiling, and analysis.
Originating from GDB/Armulator, the SkyEye project aims to provide an integrated simulation environment in Linux and Windows. It can currently simulate several popular embedded systems such as Atmel AT91 boards (from ARM7TDMI to ARM920T processors), ARM720T boards, StrongARM (SA1100/SA1110), and Xscale boards. It can run several operating systems such as ARM Linux, uClinux, and uc/OS-II (ucos-ii), and analyse or debug them at source level.
