Research Interests

My research interests combine the engineering of neuromorphic systems and the reuse methodologies for analog VLSI design. My research in neuromorphic engineering aims at designing and using integrated circuits (IC) which components and architecture are neuro-mimetic (i.e. mimic biological neural systems). This research activity has been inter-disciplinary oriented. My case study for the reuse methodologies is the optimization of the design of silicon conductance-based neural networks on analog ASICs. I particularly focus on the definition and re-use of IP-AMS definition, supported by an IP-based library of analog and mixed circuits, and its exploration tool. The IP-based library, developed for that specific application domain, accelerates the design cycle for the next ASIC generation.

Teaching activity

From 2004 to 2007, Timothée Lévi taught lessons for the course of analog and digital electronic at University of Bordeaux (from the first year to master courses).

Since 2009, Timothée Lévi has been teaching lessons of analog and digital electronics and networks at IUT GEII of Université of Bordeaux.
