Cross-Layer Design of Distributed Cyber-Physical Systems: From Physical Models to Semiconductor Reliability

In this talk we will focus our attention to embedded control systems as one possible incarnation of cyber-physical systems. Their design starts with high-level control algorithm design and ends with a concrete hardware/software implementation, involving independent design teams who work at different levels of abstraction – control theorists, compiler designers, programmers, embedded systems designers, computer architects, and semiconductor experts. As a result, design assumptions made at one layer often do not hold at other layers, thereby requiring costly, often ad hoc, ex post facto integration, testing and debugging. While this is a well-recognized problem, till date there is no satisfactory solution that integrates all the abstraction layers. We will outline the challenges involved here and discuss potential solutions. Biography Samarjit Chakraborty is a Professor of Electrical Engineering at TU Munich, where he holds the Chair for Real-Time Computer Systems. Prior to joining TUM in 2008, he was an Assistant Professor of Computer Science at the National University of Singapore. He obtained his PhD in Electrical and Computer Engineering from ETH Zurich. His research interests cover all aspects of system level design of embedded systems and software. He has published over 150 journal and conference articles in this area and his work has been funded by several governmental and industry grants, including those from General Motors, Intel, Google, BMW, Audi, Siemens and Bosch.
