Their main disadvantage is the communication delay which has to be controlled, otherwise they may become useless. Early performance assessment by using tools which process system models, helps make informed design decisions. The new standard in time-critical systems is MARTE (Modeling and Analysis of Real-Time and Embedded systems), adopted in 2008 by OMG (Object Management Group) as a new UML (Unified Modeling Language) Profile [12]. This paper focuses on automatic extraction of performance models from UML models with MARTE annotations, since most existing analysis tools are based on the now obsolete SPT (Schedulability, Performance and Time) profile. A tool called Phymss (Performance Hybrid Model Solver and Simulator) was developed to cover as much as possible from the performance analysis process; it accepts several types of diagrams, since UML allows a multitude of system views. The internal performance model for each system being analyzed is easy to refine either into an analytical model or into a simulation one. References [1] C. Chise, and I.
