The amount of software in cars grows exponentially. Driving forces of this development are the availability of cheaper and more powerful hardware, as well as the demand for innovation through new functionality. The rapidly growing significance of software and software-based functionality is at the root of various challenges in the automotive industries. These concern their organization, definition of key competencies, processes, methods, tools, models, product structures, division of labor, logistics, maintenance, and long-term strategies. This paper pinpoints the idiosyncrasies of the domain, characterizes the essentials of automotive software, and discusses the challenges of automotive software engineering

This workshop summary presents an overview of the one-day International Workshop on Software Engineering for Automotive Systems (SEAS 2006), held in conjunction with the 28th International Conference on Software Engineering (ICSE'06).

Service-based systems engineering is a recent paradigm that has proven useful for the development of multifunctional systems, whose functions may be used in different contexts and have strong interrelations and dependencies between each other. Integrated into a service-oriented development process, we present an approach for tool supported design of services and execution scenarios describing their interaction, using the tool AUTOFOCUS. It includes the application of simulation, verification of typical requirements for service-based systems using model checking, and code generation. We report on our experience with this approach by means of a case study from the automotive domain, a fairly new field of application for service-based systems engineering.

The paper describes a dynamic classmark scheme based on a finite number of stages during a radio connection procedure for reconfigurable terminals in future multiple radio access technology environments. Based on the user profile, terminal profile and service profile that the user applies, features are clustered into different sets called classmarks. The classmarks are designed in a stage-based manner in order to realize the method of dynamically creating and triggering them. During the reconfiguration, radio link establishment and communication processes, the number of stages is adaptive to the access frequency and priorities of the necessary features required by the network. Thanks to this approach, the signaling burden is highly reduced in the radio network. Therefore, the efficiency of radio resource management is improved.

The next generation UltraSPARC-I CPU represents a significant step forward in processor performance at the cost of increased design complexity.Added complexity increases the risks in achieving functionally correct first silicon.Existing design verification techniques were supplemented by applying emulation to obtain an early look at functionality.Discussed are the goals, methods and results of the UltraSPARC-I emulation.

A generalized methodology is presented which can be used to select a cost effective design-for-test technique for use in the design process. The intent is to factor in both increased research and development costs as well as increased production costs. The authors also correlate the expected levels of test coverage. Thus, for a particular design, it is possible to predict the increase in cost of research and development, and increased production costs, and correlate this with test coverage. The tangible factors in the cost of quality can be determined.>
