Modeling a BSG-E automotive system with the timing augmented description language

Modeling and analysis of time is a key issue for the correct development of an automotive distributed embedded system. The paper presents new extensions of the Time Augmented Description Language (TADL), applicable at different abstraction levels of an EAST-ADL/AUTOSAR design. The new extensions enable a precise modeling of multi clock characteristics of distributed systems together with parameterized timing expressions. In this paper, we highlight some critical issues for the high---level time modeling of a Box Servitude Generic-External (BSG-E) provided by Delphi. This industrial example illustrates timing constraints coming from both hardware and software parts of the system.

Merging the quality assessment of processes and products in automotive domain

It is commonly accepted that the quality of a product depends on quality of a process. So, many industrial companies have put effort to improve their software processes, which are mainly based on CMMI or SPICE in automotive industry. However, these processes do not pay attention to safety-related dedicated issues. We propose in this paper an instrument that allows performing a SPICE assessment as well as a safety assessment regarding the ISO 26262 recommendations. The major benefit of our proposal is that it allows focusing on assessing software by both development process quality and product quality approaches.

An Experiment on Merging Quality Assessment in Automotive Domain

Demands for process oriented development according to Automotive SPICE standard have been constantly issued by automotive companies/suppliers for many years now. Many of them have already set these up for themselves, or accordingly aligned their improvement projects on these recommendations. With the adoption of the new ISO26262 safety standard, their main preoccupation is to check whether what they already achieved for SPICE can still be used and smoothly integrated in a larger framework to meet ISO26262 requirements. This paper discusses our proposal regarding an experiment based on a SPICE-based model assessment for safety engineering with the ISO26262 automotive standard.
