Verifying robust frequency domain properties of non linear oscillators using SMT
Hafizul Asad, Kevin Jones, Frédéric Surre · 2014
We present a novel mixed time and frequency domain approach to the formal verification of oscillators properties which are specified in the frequency domain. We use robust periodogram specification to specify the oscillator behaviour in the close vicinity of the limit cycle. Using SAT modulo ODE (SMO) for Bounded Model Checking (BMC) of the non-linear hybrid automata, we show that the oscillator hybrid timed traces satisfy frequency domain specifications.
