Why Papyrus?

• Software industry shift continuing:– Build ? Buy ⟼ ? Use⟼– Proprietary ? Open⟼

• Opportunity to organize and provide industrial strength alternative to proprietary tools

Embedded vs. other systems

• Single purpose– Specialized Hardware and software

• Limitations– Memory, processor, interfaces

• Timeliness of execution– Cost of missing deadlines

• Resiliency

What is MARTE?

• Industry-standard language• DSL for specifying and analyzing real-time and

embedded systems• Refines UML concepts for real-time domain



© 2014 Zeligsoft

Why MARTE?

• Provides accurate and precise modeling of– Qualitative and quantitative, functional and non-

functional characteristics of real-time software applications

– Time and temporal relationships– Different kinds of hardware and software

resources and allocations

MARTE

• MARTE spec– ProMARTE consortium, of which

the CEA is a member

• Papyrus was used for the examples in the book

Automation

Why UML-RT?

Abstraction• Code generation• Runtime layer

– Adaptability• Platform• Language


Proven approach

• Constrained UML– Easier to learn and use

• Less concepts

– “The model is the code”

• UML-based DSML

What is UML-RT?• Structured Classifiers

• ROOM Actors and RoseRT/RSARTE capsules

• Protocols• “collaboration of pairs of provided/required interfaces”• “standard” classes used for carried data

• Ports• Typed with (conjugated) protocols

• Hierarchical state machines• Part of the structured classifiers

Coming soon to a Papyrus near you!

• UML-RT– “ROOM on UML”– Runtime service layer– Transformation (code generation)


All Open Source

SysML

• Not directly related to Real Time Embedded– Often part of larger systems

• Used by systems engineers– Drive requirements and architecture into devices

that have embedded software• Continuity across disciplines
