Publications

Research

I have been working on two main research lines: Emerging Computing paradigms based on emerging device technologies and Hardware Dependability.

Emerging Computing paradigms

The research on emerging computing paradigms targets the invention, design, prototyping and demonstration of disruptive computing accelerators/engines by making use of unique features of emerging devices such as memristors and spintronics, while mainly focusing on energy-constrained low-granularity computing for a wide range of edge applications, including AI, such as personalized healthcare, smart environments and drones.  Examples of topics include computation-in-memory, new hardware architectures of AI, neuromorphic computing, spin-wave computing, etc. we adapts a holistic approach in which it addresses the whole computing engine design stack. The research is being performed in many partners such as TU Eindhoven in the Netherlands, RWTH in Germany, IMEC in the Netherlands and Belgium, European Space Agency in the Netherlands, IBM in Switzerland and in USA, etc.

  • Micro-architecture and circuit design: in which dedicated accelerators are defined and designed; logic and arithmetic operations are developed and designed based on emerging devices.
  • Architecture design: where different specialized accelerator are integrated while considering different metrics such as optimization of communication, power and control logic, as well as maximizing the parallelism and throughput.
  • Compilers and mapping methods: in which a programming interface and the mapping of (parallel) algorithms on the developed architecture are under study.
  • Algorithms and application: in which applications and algorithms supporting massive parallelism are investigated in order to analyze their suitability for emerging computing paradigms/ architectures.

Hardware Dependability

Research on hardware dependability aims at developing appropriate solutions that can guarantee the manufactured chips/ hardware are reliable and trustworthy.  This research is being performed in collaboration with many partners such as NXP in the Netherlands, IMEC in Belgium, Cadence in USA, Qualcomm in USA, European Space Agency in the Netherlands, Polito Di Torino in Italy, Karlsruhe Institute of Technology in Germany, Rescure in The Netherlands, Netherlands Forensic Institute (NFI) in the Netherlands, etc. The focus of this research is:

  • Testability: This includes understanding the weaknesses of new technology nodes and integration, developing appropriate fault models and test solutions that can enhance the outgoing product quality and reduce the cost. A lot of attention in our research is given to memories both traditional as well as emerging ones.
  • Reliability: This includes the analysis of reliability failure mechanisms and their impact on the chip life time and failure rate, developing prediction models, design-for-reliability and mitigation schemes, etc.
  • Hardware Security: This includes Physical Unclonable Functions technology for strong security and authentication solutions, analysis of security weaknesses of hardware and development of design-forsecurity solutions and secure ICs, etc.
