Mathematical Modeling and Simulation from VLSI to Cyber-Physical Systems

April 17, 2014

In many engineering disciplines, mathematical modeling not only provides a way to construct structured views of the observation data, but also deeper understanding of the underlying engineering phenomena. Moreover, mathematical models also provide engineers with a way to see connections between different problems and to conceive innovative solutions. In the first part of this talk, I will present novel approaches to address some modeling and optimization challenges in computer engineering. In particular, I will present a method to model spatial non-uniformities in VLSI design, and an efficient mathematical mask synthesis method in semiconductor manufacturing. I will also show how mathematical modeling can help us connect two seemingly unrelated problems: circuit simulation and river dynamics simulation. By exploiting the network nature of the circuits and rivers, we can construct highly efficient river dynamics simulation solutions, with big cyber-physical system modeling implications. In the last part of this talk, I will present some of the challenges in computer engineering and future research directions.
