The analog circuit design process is becoming very complex
and therefore new verification approaches are very much
needed. While formal verification requires human expertise, numerical and statistical methods lack completeness.
Qualitative simulation, on the other hand, is a semi formal
method for fuzzy dynamical system simulation. It has the
advantage of generating complete and sound envelopes of
trajectories.
We propose a verification environment for analog circuits behavioral properties checking
based on qualitative simulation. We automatically extract
analog circuits models and compute their qualitative behavior for ranges of parameters and initial conditions. Then, we
verify their properties on the generated state space bounds. The effectiveness of the method is illustrated with
a tunnel diode oscillator.
