RTSim

RTSim, latest version 2.0.0001, is a powerful simulator for real-time systems developed by OSI Software, Inc.. This remarkable tool caters specifically to the Education sector, under the Science Tools subcategory, and is available as Freeware. The main program file, RTSim.exe, ensures a smooth user experience on supported operating systems like Windows XP, and 7.

Within RTSim, there are four integral components making it a versatile tool. Metasim serves as a generic library for simulation of discrete event systems. For those interested in simulating scheduling algorithms and real-time tasks, the rtlib library, which builds upon metasim, is indispensable. Additionally, there are optional components such as ctrlib, which simulates real-time control systems though it requires the Octave library, and jtracer, a Java-based tool for visualizing schedule traces generated by a rtlib program.

Initially developed as an internal project at Scuola Superiore Sant'Anna, RTSim has evolved significantly owing to the contributions of numerous PhD students involved in various research projects. It boasts previous versions like 2.0, and 1.0, each contributing to its current state of functionality and versatility.

The program is easy to download and completely free, making it highly accessible for students and researchers alike.

Pros:

• Comprehensive tool for simulating real-time systems
• Includes a robust set of libraries for diverse simulation needs
• Freeware license makes it accessible to a wide audience
• Ease of download and installation for supported OS

Cons:

• Advanced features like ctrlib require additional libraries such as Octave
• Only supports Windows XP/7, limiting its usability on newer operating systems

RTSim stands out as an extraordinary tool for those diving into the realm of real-time system simulations, providing a robust, free solution with a rich set of features.
