A Model-driven Development Approach with Temporal Awareness for Vehicular Embedded Systems
Publication Type:
Doctoral Thesis

Abstract
Considering the ubiquitousness of software in modern vehicles, its increased
value and development cost, an efficient software development became of paramount
importance for the vehicular domain. It has been identified that early
verification of non functional properties of vehicular embedded software such
as, timing, reliability and safety, is crucial to efficiency. However, early verification
of non functional properties is hard to achieve with traditional software
development approaches due to the abstraction and the lack of automation of
these methodologies.
This doctoral thesis aims at improving efficiency in vehicular embedded
software development by minimising the need for late, expensive and time consuming
software modifications with early design changes, identified through
timing verification, which usually are cheaper and faster. To this end, we introduce
a novel model-driven approach which exploits the interplay of two
automotive-specific modelling languages for the representation of functional
and execution models and defines a suite of model transformations for their automatic
integration. Starting from a functional model (expressed by means of
EAST-ADL), all the execution models (expressed by means of the Rubus Component
Model) entailing unique timing configurations are derived. Schedulability
analysis selects the set of the feasible execution models with respect to
specified timing requirements. Eventually, a reference to the selected execution
models along with their analysis results is automatically created in the related
functional model to allow the engineer to investigate them.
The main scientific contributions of this doctoral thesis are i) a metamodel
definition for the Rubus Component Model, ii) an automatic mechanism for the
generation of Rubus models from EAST-ADL, iii) an automatic mechanism for
the selection and back-propagation of the analysis results and related Rubus
models to design level and iv) a compact notation for visualising the selected
Rubus models by means of a single execution model.
