A open-source real time scheduling simulator. Cheddar should run on Linux, Solaris and win32 boxes. Cheddar provides tools to do simulations with classical real time scheduling algorithms and tools to test task feasability.

Some very useful material including the study: What makes a good RTOS?

Goal: develop method to design real-time systems that: is practical for large scale, complex systems; includes support of OO techniques to achieve reuse in implementations; helps visualize and test design concepts during early stages when main decisions are made.
