The LSV seminar takes place on Tuesday at 11:00 AM. The usual location is the conference room at Pavillon des Jardins (venue). If you wish to be informed by e-mail about upcoming seminars, please contact Stéphane Le Roux and Matthias Fuegger.
The seminar is open to public and does not require any form of registration.
In this talk, we consider verifying properties of mixed-signal circuits, i.e.,
circuits for which there is an interaction between analog (continuous) and
digital (discrete) values. We use a simulation-based approach that consists of
evaluating the property on a representative subset of behaviors, generated by
simulation, and answering the question of whether the circuit satisfies the
property with a probability greater than or equal to some value. We propose a
logic adapted to the specification of properties of mixed-signal circuits, in
the temporal domain as well as in the frequency domain. We also demonstrate
the applicability of the method on different models of Δ-Σ modulators
for which previous formal verification attempts were too conservative and
required excessive computation time.
