This paper describes a new approach for analogue/digital verification extending to mixed signal digital concepts such as random constrained stimuli generation, data/protocol checking and functional coverage. A special architecture has been defined for probe and source terminals that bridge analogue and digital domains: such architecture allows an optimized interaction between analogue circuit description and object-oriented verification languages such the “e ” used by Cadence Specman Elite. This approach has been used to build a Mixed Signal Verification Kit that dramatically improves analogue/digital verification quality and productivity. The kit is composed by configurable probe and source terminals, ready-to-use verification components for analogue blocks (such as oscillators, DC-DC converter and so on), pre-defined coverage items based on analogue metrics, checks and driving sequences addressing analogue parameters and by a user-friendly graphical interface that automatically sets up the complete verification environment. In the following, it is shown how concrete advantages in terms of verification effectiveness, results collections and bugs discovery are obtained by using the Mixed Signal Verification Kit on a set of mixed signal IPs. A benchmark involving different DUT complexity levels is also described to compare standard flow with the new one.
