|Verifying the EMC Behavior of Automotive ECU Systems using an Integrated Simulation Approach (In German)|
The increasing electrification of modern automotive platforms is causing significant challenges for development teams to assess and verify the EMC behavior of these systems. In order to meet the stringent quality, cost and time-to-market requirements automotive developers leverage simulation-based methodologies to accomplish this challenging task. In order to gain the most out of a simulation-based development approach it is beneficial to leverage the strengths of different analysis methods and integrating them into one single system solution. The software companies Synopsys Inc. and CST AG launched a technology partnership in 2012 in order to integrate their complementary strengths to combine system simulation and structural EM simulation. This includes Synopsys’ electrical system level solution Saber and CST STUDIO SUITE. The technology development for this product integration has been initiated and driven by the leading German automotive supplier Bosch. In this article Synopsys, CST and Bosch present an overview of this solution and demonstrate a use case how the new product integration helps solve sophisticated engineering problems in order to ensure that final automotive product requirements are met.

|Robustness Validation, Part 2: Searching for the Worst Case (In German)|
In terms of quality, robustness, reliability and safety aspects it is mandatory to validate whether the system implementation satisfies the needs of the specification. An important part of this validation is the analysis of the worst-case behavior of the system. However, using only hardware-based testing approaches it is often not possible to test the system implementation under true worst case conditions, and overly conservative assumptions must be made to ensure system reliability. Specifically in the design specification phase, simulation is the only choice to accurately predict the worst case behaviors of the system under test. This article provides an overview of the new Worst-Case Analysis (WCA) solution included with the Saber suite of simulation tools.
