The evolution in automotive qualified electronic components, including the birth of powerful multicore System-on-Chip (SoC) platforms has fundamentally changed the approach to designing automotive electronic systems today. This evolution is not only happening on the hardware side, but also on the software design side where there has been consolidation of multiple domains onto a single SoC. This type of consolidation allows shorter time-to-market with consumer-ready features to address immediate market demands. This paper explores the reasons for this trend and available architectures for achieving consolidation. AUTOSAR on Linux is one of those architectures and has been popular in Advanced Driver Assistance Systems (ADAS) and infotainment applications, allowing complex functions to smoothly integrate into the vehicle network.

Communication between electronic control units (ECUs) and vehicle gateways can span LIN, CAN, FlexRay, and Ethernet. Designing an in-vehicle network supporting multiple car platform variants, with respect to selecting the appropriate technology to connect ECUs and gateway networks, and making timing based analysis and synthesis is extremely challenging. This paper discusses how to handle a variety of communication protocols on an individual network level and how multiple networks relate to the overall communication design of a vehicle platform ensuring consistent variants.
