Analog and mixed signal (AMS) designs are integrated circuits required at the interfaces of a system-on-chip or embedded system with the physical environment. The verification of AMS designs is concerned with the assurance of correct functionality, in addition to checking robustness with respect to different types of inaccuracies like parameter tolerances, nonlinearities, etc. In this talk, I will review recent research on the application of formal methods to the verification of AMS designs and present some successful approaches based on techniques such as Model Checking, Constraint based verification, Run-time verification, Assertion based verification, and Automated Theorem Proving. These approaches handle continuous as well as discrete-time AMS designs with both linear and non-linear behaviors. To illustrate the effectiveness of above techniques, I will use as case studies several examples of analog and mixed signal systems, like oscillator circuits, switched capacitor based designs, Delta-Sigma modulators, PLLs, etc.
