1. Mission profile-based assessment of semiconductor technologies for automotive applicationsInfoDetails

   Ali Ahari, Alexander Viehl, Oliver Bringmann, Wolfgang Rosenstiel, 2018

   Semiconductor technology has to be qualified under the harsh temperature conditions required by the AEC-Q100 qualification standard before it is applied in the automotive sector. In this paper, we propose a framework to assess different semiconductor technologies for typical automotive electronics components considering both AEC-Q100 temperature specifications and real world automotive environmental temperature profiles as given by mission profiles. The results of the use-case on SRAM indicate that the conventional qualification process based on AEC-Q100 significantly underestimates the reliability of advanced semiconductor technologies and prevents their application in automotive electronics. Qualification based on AEC-Q100 also slightly underestimates the power and performance, however, the amount of underestimation reduces by technology scaling. In addition, our analysis shows that technology scaling does not lead to a performance boost in typical automotive applications due to severe reliability challenges of advanced technology nodes in automotive environments. As a consequence, we consider mission profile-based technology assessment as a promising alternative to the qualification of semiconductor technologies in automotive applications.

1. CTEF: Collaborative Technology Evaluation FrameworkInfoDetails

   Ali Ahari, Jan Novacek, Alexander Viehl, Oliver Bringmann, Wolfgang Rosenstiel, 2018

   The adoption of advanced semiconductor technolo- gies in automotive electronics introduces new qualification chal- lenges. In this paper, we propose a framework that provides an environment for all partners in the supply chain to collaborate in seamless assessment of a new technology during all development phases. The framework enables the assessment of system char- acteristics such as reliability and power without requiring any intellectual property exchange. The proposed methodology adapts the continuous change of internal models automatically, supply chains and parameter interdependencies during the different design phases. It also supports early decision-making throughout system planning and the identification of alternative suppliers. The framework’s applicability has been evaluated exemplary by assessing the reliability of an autonomous car. We show that the overall car reliability can be improved by up to 7.4% by selecting appropriate suppliers and technologies.
