Systems and network integration is a major challenge, and systematic analysis of the complex dynamic timing effects becomes key to building reliable systems. Very often, however, systematic analysis techniques are (considered) too restrictive with regard to established design practice. In this paper lessons learned from real-world case studies are presented, in which OEMs have used the new SymTA/S (Symbolic Timing Analysis for Systems) scheduling analysis technology to evaluate different network choices with minimum effort. Thanks to its flexibility, SymTA/S can be applied in a number of non-ideal situations, where other, more restricted approaches have inherent weaknesses. The approach is applicable to more than one involved party, as buses typically connect several ECUs (Electronic Control Units) and can further form heterogeneous networks with bridges, gateways. Finally the approach was put into relation with ongoing standardization activities and supply-chain-issues.
