RAPID RMA for IBM Rational Rose RealTime: The Art of Modeling Real-Time Systems in UML

Combining Rate Monotonic Analysis (RMA) with the visual modeling environment of IBM Rational Rose® RealTime, RAPID RMA for IBM Rational Rose RealTime helps real-time software developers 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, Rose RealTime 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, RAPID RMA for Rose RealTime verifies the performance of the design throughout this cycle. RAPID RMA for Rose RealTime 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, RAPID RMA Rose RealTime 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 deadlines using the resources specified.

Product Availability
RAPID RMA for IBM Rational Rose RealTime is availble now for download. The UML components are contained in the main RAPID RMA for Windows installation package. Rose RealTime may become unavailable from IBM due to the product reaching EOL. Since this is the case TPSI will not be creating new versions of RapidRMA for Rose RealTime.
