RapidRMA for Telelogic Rhapsody: The Art of Modeling Real-Time Systems in UML

Combining the Rate Monotonic Analysis (RMA) of RapidRMA™ with the visual modeling environment of Telelogic Rhapsody®, RapidRMA for Telelogic Rhapsody allows real-time software developers to prevent costly design mistakes and accelerate their development schedules. Through the industry standard Unified Modeling Language™ (UML), plus real-time design constructs, code generation, and model execution, Telelogic Rhapsody addresses the complete lifecycle of a project— from early use case analysis, through design, implementation, and testing. By providing timing extensions to the UML language, RapidRMA for Telelogic Rhapsody verifies the performance of the design throughout this cycle. RapidRMA for Telelogic Rhapsody maintains timing analysis results in the UML model, and allows designers to test software models against various design scenarios and evaluate how different implementations might optimize the performance of their systems. By isolating and identifying potential bottlenecks in both soft and hard real-time systems, RapidRMA for Telelogic Rhapsody can reduce development costs and avoid many hours of wasted manpower.

“Our systems need to meet explicit quantitative performance goals. If you miss a timing sequence when designing a satellite, it falls out of the sky. RMA-based tools are the only ones that can perform the sophisticated technical analysis we need to assure quality real-time system design.”
- Lockheed Martin

What is Rate Monotonic Analysis?

Rate Monotonic Analysis (RMA) is a collection of quantitative methods and algorithms used to analyze real-time systems. The analysis determines whether your system is schedulable. In other words, RMA determines whether all tasks will execute by the appropriate dealines using the resources specified.
