Rational Rose RealTime

The Real-Time Embedded ChallengeSoftware development teams all face the same software development paradox — how todevelop applications faster without compromis-ing quality. Developers of real-time embeddedsoftware face additional challenges. Such soft-ware is highly event driven, concurrent, andoften distributed. Stringent requirements mustbe met for latency, throughput, and dependabil-ity. The capture and effective communication ofdesigns for such systems is a daunting task.

Rational Rose RealTimeRational Rose® RealTime is a complete lifecycleUnified Modeling Language™ (UML) develop-ment environment expressly created to meetthese real-time embedded challenges. It pro-vides a UML-compliant solution to the uniqueproblems of concurrency and distribution.Rational Rose RealTime unifies the project teamby providing an extensive set of tool integra-tions to meet the needs of the entire team, fromrequirements capture through to high-perform-ance code generation, testing, and debuggingfor real-time operating system targets. In comb-ination with the Rational Unified Process™, yourproject has a proven pragmatic approach to re-ducing development risk.

• A UML model compiler generates complete C, C++, and Java applications for UNIX,Windows NT/2000, and real-time operatingsystem targets. This automated code gener-ation eliminates the need for manual transla-tion and avoids costly design interpretationerrors.

• An associated visual UML model debuggerenables observation and validation of hostand target applications. Model execution encourages early design refinement.

• A complete UML-based testing facility letsthe user graphically define system behavior,then automatically generate and executetest cases and test suites for complete orpartial models. It supports continuous verifi-cation of quality right from the beginning ofsystem implementation.

The Real-Time EmbeddedDevelopment ChoiceRational Rose RealTime is based on market-leading technology that extends Rational Rose,the world’s leading visual modeling tool, withfield-proven UML model code generation andvisualization.

“Rational Rose RealTime's

strengths are in modeling,

code generation, and the

visualization of models during

execution. IDC's opinion is

that these key features cou-

pled with the full complement

of industry-standard UML

support makes Rational Rose

RealTime a major contender

as the de facto standard for

real-time embedded system

development.”

Steve Garone, ResearchDirector for International DataCorporation (IDC)

UML supports the entire softwaredevelopment lifecycle

Iterative DevelopmentRational Rose RealTime supports an iterativedevelopment strategy that reduces yourdevelopment risks. Reverse engineering enablesyou to understand your existing systems. Codegeneration technology lets you compile and exe-cute your designs at the earliest stages of prod-uct inception. Early execution on the host or tar-get platform provides you with the feedback youneed to discover and correct design flaws earli-er, lower costs, and minimize risk.

Rational® QualityArchitect RealTime is an exten-sion to the visual modeling capability ofRational Rose RealTime. It enables RationalSuite DevelopmentStudio RealTime Editionusers to perform model-based component test-ing by generating code automatically from with-in the Rose RealTime model. For the first timeyou can automatically build stubs and driversto use in testing components and classes. And,these generated tests can be executed auto-matically. Rational QualityArchitect RealTimesupports a wide range of testing activities fromdeveloper scenario-based debugging to fullsystem regression testing.

Optimized Design Concepts

With Rational Rose RealTime, you model arch-itectures and designs in a natural way that mir-rors how real-time embedded systems actuallywork. For example, concurrency is inherent insuch systems, and the resultant interactionamong concurrent threads of execution raisesmany design challenges. A best practice solu-tion to handling concurrency is the activeobject design pattern. Active objects encapsu-late their own thread of execution thus prevent-ing thread interaction problems. Since theycommunicate through message-based inter-

face ports, like the pins on hardware integratedcircuits, they adapt well to various reuse anddistribution situations. Active objects can beflexibly mapped to operating system threadsand processes.

In Rational Rose RealTime, active objects aremodeled as UML-compliant capsules.Capsules can be hierarchically decomposedinto collaborating sub-capsules, and thus canbe used throughout the development cycle —from executable architectures to lowest-leveldesign elements. Capsules enable your teamto design real-time embedded systems the waythey really operate.

Productivity Depends on Clear CommunicationReal-time embedded systems often requirelarge-scale development teams to handle thecomplexities of design and construction.Without good communication and the clearcapture of system architecture, developing insuch an environment can be disastrous.Rational Rose RealTime can help you avoidsuch pitfalls.

• Improve communication between all members of your team through the power of the UML.

• Integration between Rational Rose RealTimeand Rational Requisite Pro® ensures that norequirements get lost in translation from requirements to design.

• Capture your architecture more effectivelyand make it part of the implementation.

• Publish your designs to the Web usingRational Rose RealTime’s Web Publisher.You can automatically generate documentsvia the integration between Rational RoseRealTime and Rational SoDA®.

• Software Configuration Management and Version Control tool integration allows you to use products like Rational ClearCase®

to more effectively manage your UML application development.

A Complete Embedded SolutionThe Rational Embedded Solution includesRational Rose RealTime and Rational TestRealTime. Test RealTime supports thoroughverification of mission-critical and safety-criticalsystems at the unit, object and system level. Itprovides full trace, coverage, memory analysis,and performance observation both on thedevelopment host system and the target sys-tem to ensure complete testing in the mostdemanding applications.

An Open Platform EasesIntegration and AdoptionRational Rose RealTime is designed for sim-plified and streamlined insertion into your soft-ware development environment, processes,and workflows. Seamless integration with otherRational® Software products and support for adiverse set of commercial real-time operatingsystems offers development teams a completesolution that no other vendor can match.

Support for leading compilers and symbolicdebuggers keeps you in control of your design.These integrations let you focus on the designof your software, rather than on the develop-ment environment or on tool interoperabilityissues.
