Nucleus RTOS is a real-time operating system (RTOS) and full-featured toolset created by the Embedded Systems Division of Mentor Graphics for various CPU platforms. Nucleus RTOS is part of a complete embedded solution with a full complement of embedded middleware available.
Development is typically done on a "host" machine running Windows or LINUX. Target applications can be compiled to run on various "target" CPU architectures and tested using the actual target boards, simulators or via the "host" using EDGE SimTest.
The Nucleus RTOS is designed for embedded applications including consumer electronics, set-top boxes, cellular phones, and other portable and handheld devices. For limited memory systems Nucleus RTOS can be scaled to a footprint as small as 13 KB for both code and data.
The small footprint is the main reason for using Nucleus. Since the multitasking is quite primitive, and the debugging tools are not the best, it can be a difficult environment to work with.

EDGE Development Suite is an integrated embedded development environment which incorporates a project manager, source editors, compiler tools, debugger, profiler and prototyping in a single, easy-to-use graphical environment.
The development suite is actually just an eclipse plugin. Unfortunately many of the nice things about Eclipse have been disabled in this environment, for example, if there is a compiler error, it is often not possible to double-click on the error to jump automatically to that section of code. Many of the refactoring capabilities have been disabled, as has code folding.
EDGE SimTest is a prototyping environment that enables you to build embedded applications on a development host such as Microsoft Windows™, prior to embedding on target hardware.
Integrated JTAG probe connection support.
