Background: Matlab Simulink
Matlab: multi-paradigm numerical computation o matrix operations, algorithm development, data
visualization etc.
Simulink: dataflow modeling environmento Modeling and simulating
dynamic systems
o Block diagram based
Large user base > 1Mo Automotive
o Avionics
o Railway
o Etc.

Motivation: yet another tool integration
Started in 2011 (as a second iteration)o Provide HW-SW allocation for early simulation of avionics
systems
o Input: Low-level Simulink libraries
o Output: Integrated HW-SW Simulink model
Allocation defined on high abstraction level Eclipseo Hierarchical graph based visualizations yFiles + EMF-IncQuery Viewers
o On-the-fly model validation EMF-IncQuery
o Generic bridge between Matlab Simulink and EclipseMassif

Massif
Integrating Eclipse and Matlab Simulink
Eclipsecon 2015
Massif – Eclipse-Matlab Simulink bridge Generic Bridge between Matlab Simulink and Eclipse
o Import/Export Matlab Simulink systems and librarieso Traceability for incremental processingo Multiple import options for different usage scenarios
• e.g., analysis or allocation
User-friendly EMF representationo Manipulating systems/libraries directly on EMF levelo Support for easier navigability
Works with Matlab license servero Can connect to a running Matlab instance
Pure Java realization, EPL licenseo Project specific constraint!

Additional Features
Import Filterso For leaving out unwanted elements/details
from imported models
Bus creator and selector configurationo Configured via string (fqn like) in
Matlab Simulink
o Use EMF EReferences to define and Massif automatically calculates configuration
Easier Block-to-Block navigabilityo Derived EReferences defined by EMF-IncQuery
