Formal Verification of Analog and Mixed Signal Designs: Survey and Comparison

Analog and mixed signal (AMS) circuits are important integrated circuits that are usually needed at the interface between the electronic system and the real world. In contrast to digital designs, verification of AMS systems is a challenging task that requires lots of expertise and deep understanding of their behavior. Researchers started lately studying the applicability of formal methods for the verification of AMS systems as a way to tackle the limitations of conventional verification methods like simulation. This paper surveys research activities in the formal verification of AMS designs as well as compares the different proposed approaches
