Modern smart systems are usually built by implementing SW functionalities executed on HW platforms composed of both digital and analog components. Validation is mainly implemented through simulation of the functional behavior of the entire smart system modeled by a Virtual Platform. It is thus crucial to achieve fast mixed-signal simulation by removing unnecessary overhead due to synchronization between multiple tools and unimportant details. This work proposes a methodology to abstract mixed-signal systems, by integrating digital and analog components in a homogeneous virtual platform model for efficient simulation. Two main contributions are provided: 1) an automatic abstraction technique for analog components, allowing to preserve only the details meaningful for the functional behavior of the entire platform by moving complexity from simulation to generation time and 2) a novel scheduling technique that exploits temporal decoupling and synchronization of digital and analog processes, to simulate them together in a homogeneous model.
