Project Overview
Project

• Goal Add SMP2 Support to EuroSim Mk4
• Work started End 2004
• EuroSim Mk4 Released 2006
• Consortium effort
• NLR SMP2 tools including SMP2 Editor
• Dutch Space Integration with EuroSim core
• Atos Origin Verification Validation of the
  software
• Partially funded by NIVR

Project Aims
Project

• Build an SMP2 model development and simulation
  platform on top of EuroSim
• Makes EuroSim a suitable candidate for use in
  SMP2 based simulation projects
• Full integration of SMP2 models in the EuroSim
  real-time simulation environment
• Make available EuroSims hard real-time
  simulation capabilities to the SMP2 community
• Allow re-use of legacy EuroSim and SMP models
  together with SMP2 models without additional
  software layers
• SMP2 tools fully integrated in the existing
  EuroSim GUI and way of working
• Easy to learn and easy to use for the EuroSim
  user
• Optimal tool support and documentation for SMP2
  model developers

SMP2 Standard High-level objectives
Standard

• Model Portability between Simulation Environments
• Model Portability between Platforms(i.e.
  Operating Systems and Middleware)
• Ease Data Exchange between System Engineering and
  Simulation domains
• Promote Model Reuse
• Support for Model Integration (Plug Play)
• Support for configurable and flexible simulations
• Support for machine-readable model Metadata
• Based on Open Standards (UML/XML)

Design

• Enhanced Model Editor
• Add SMP2 file nodes to EuroSim model file
• Start SMP2 Editor for editing catalogues
• SMP2-aware simulator building process
• Graphical SMP2 Editor
• EuroSim look and feel
• To be started from EuroSim Model Editor
• Supports most features of catalogues
• Integrated catalogue validator enforces validity
  of catalogues during editing
• SMP2 Validator
• Optional validation functionality available
  from within SMP2 Editor
• Command line tool

Implementation in EuroSim Development
EuroSim

• SMP2 Code Generator
• Generate necessary all C code header files,
  implementation files, boilerplate files
• Minimizes implementation effort for model
  developer
• Integrated in SMP2 Editor
• Usable as command line tool
• Generated code based on SMP2 MDK
• Many code generation options
• Model developer must implement model
  functionality
• Compilation of generated code is integrated in
  simulator build process

Implementation in EuroSim Integration
EuroSim
Integration

• SMP2 Glue code generator for integration of
  SMP2 model instances in EuroSim
• Generate code for instances of models (entry
  points and instance creation)
• Replaces Assembly functionality
• EuroSim Parameter Exchange and Model Description
  Editor functionality available for SMP2 model
  instances
• Integrate SMP2 models with SMP1 and EuroSim models

Implementation in EuroSim Execution
EuroSim
Execution

• EuroSim Schedule Editor functionality available
  for SMP2 model instances
• Based on the Glue code generation utility
• SMP2 Schedule not yet supported
• SMP2 Schedule currently lacks high-frequency hard
  real-time features

Concluding Remarks
Conclusion

• EuroSim Mk4 acts as an integration platform for
  SMP2 models, SMP1 models, and EuroSim native
  models
• SMP2 features fully integrated in existing
  toolset and way of working
• EuroSim Mk4 implements most catalogue features
• Graphical Editor
• Code Generation
• Future developments will aim at full SMP2 support
