ABSTRACT
Complex mixed-signal systems, whether they are SiP or SoC designs, involve the merging of divergent analog and digital design flows. Realization of the digital circuitry is availed by synthesis and timing closure tools. Simulation cycles are often minutes to hours and set an expectation for the schedule/coverage trade-offs of the SiP chip-set. The event-driven mixed-signal (EDMS) modeling technique described here is an approach that allows models of analog components to be simulated in digital simulators. A properly configured modeling environment eliminates the need for extensive cross-training that would otherwise be required to deploy an EDMS modeling method to design teams. Creating behavioral models that match the specification of a circuit design is straightforward. However, creating and maintaining models that match the actual circuit implementation is much more intricate, and it is required for accurate system verification.
