The overall complexity of future cars requires new design methods for effective and high quality results. A new VLSA-approach (VLSA = Virtual Leveled Systems Architecture) for modelling networked systems is proposed. As a support for the application design engineers a set of so-called Virtual Memory network drivers is described encapsulating the implementation details of the actual network protocol resulting in more economic and higher quality solutions. In the first step a software network driver set for VMO-level (VMO = Virtual Memory driver level O) is proposed for CAN networks based on 96- and 51-family controllers. As a complement to the design phase support a set of network development tools is mentioned helping the engineers in the test phases of networked systems.

Cars networked electronics represent very complex systems. Ruling this complexity is a great challenge to future cars system designers. As there are no analytic solutions to the problem only good modelling in conjunction with trial and error methods will be apropriate to attack the problem. In order to produce results in a timely and cost effective manner a new generation of System Design Tools is needed to support the system design process. In the following paper a new method for assessing the system design problems is proposed: VLSA - Virtual Leveled System Architecture. A set of Network Development Tools - Simulator, Emulator, Analyzer, etc. - is discussed as the basis for efficient system design support.

Future cars' architecture will be based on networked electronics. Designer of such networked systems envisage a new class of highly sophisticated complexity. Therefore a new class of appropriate system design support tools is required. This paper describes a full set of such tools, consisting of a Network Simulator, a Network Emulator and a Network Analyzer. The Simulator is used for system layout purposes without the need for actual system's hardware. The Emulator replaces in real time real system's component. The Analyzer is used for verification of the system's layout in the actual real system. As network is the backbone of future cars' systems network development tools are fundamental for efficient cars' system design.
