A Mixed-Signal Verification Kit for Verification of Analogue-Digital Circuits

This paper presents an innovative approach for analogue and mixed-signal verification. It consists in a "verification kit" that makes use of concepts used in state-of-art digital verification, such as automatic results collection, coverage elaboration, data checking capability, pseudo-random and constrained stimuli generation. Using a bandgap cell as case study, the paper shows as the presented approach allows a precise definition of the verification space and a saving of more than 50% of the total verification effort respect traditional verification methodologies. The paper shows also how the approach can be extended to more complex mixed-signal systems
