The Integrated Systems Laboratory (Laboratoire des Systèmes Intégrés – LSI) studies design technologies for circuits and systems. The objective is to research the interplay of hardware and software design for traditional (computation on silicon) and non-traditional (nanotechnology and biosensors) systems. Topics of research include, but are not limited, to the following areas.
Design technologies for nanosystems, i.e., integrated systems that leverage emerging nanotechnologies. This area includes the modeling of hardware with dedicated languages, the compilation of hardware models into circuits, the relation between hardware and software design and its concurrent design (co-design), the system-level optimization from multiple objectives (e.g., performance, energy consumption, yield). The novel thrust in this area comes form the exploration of the use of new circuits technologies (e.g., silicon nanowires, carbon nanotubes, etc) within system design. These new technologies present unprecedented advantages and challenges, the former being related to the very high device density and the latter the large presence of defects.
Design and fabrication of bio-sensors and bio-interfaces, such as protein and ion sensors, to probe biological mechanisms for both clinical and biodiscovery objectives. Research involves both the design of novel hardware, mixing in situ computational units with biosensors, and the development of software systems for data analysis, including data integration methods for diagnosis and medication control and/or design. Specific examples are the design of wearable medical devices for continuous real time metabolic monitoring and the design of intelligent, safe and reliable drug delivery system.
Our paper “Reversible Pebbling Game for Quantum Memory Management” has been acknowledged with the Best IP Award 2019 at the DATE conference in Florence. The paper is authored by Giulia Meuli, Mathias Soeken and Giovanni De Micheli from our lab in collaboration with Martin Roetteler and Nikolaj Bjorner from Microsoft.
