I’m excited to share that our journal article “CompDSE: A Methodology for Design Space Exploration of Computing Subsystems within Complex Cyber-Physical Systems” has been accepted for publication in IET Cyber-Physical Systems: Theory and Applications! The article, first-authored by Faezeh Sadat Saadatmand, outlines the model-based Design Space Exploration (DSE) approach we used in the DSE2.0 project. This project is a collaboration between Leiden University, the University of Amsterdam, and ASML, and is co-funded by NWO and TNO-ESI.
Our work addresses the need for efficient DSE techniques to evaluate potential design decisions and their impact on non-functional aspects like performance, reliability, and energy consumption in next-gen complex distributed cyber-physical systems (dCPS).
In the article, we introduce CompDSE, a methodology designed to facilitate the DSE of complex dCPS, with a focus on the computing subsystems. CompDSE uses abstract models of the application workload, computing hardware platform, and workload-to-platform mapping, all automatically derived from runtime trace data. These models are integrated into a discrete event simulation environment to explore various design points.
We demonstrate the effectiveness of our methodology through a case study on the ASML Twinscan lithography machine, a complex industrial dCPS. The results show potential performance enhancements by optimizing computing subsystems while considering physical constraints. Each design point evaluation takes less than a minute, highlighting CompDSE’s efficiency and scalability in tackling complex dCPS with large design spaces.
