Mixed-Mode Design: Experiences with Multi-Level Macromodeling

For simulation in mixed-mode design appropriate macromodels have to be developed. A successful approach is the combination of analog and digital, time-continuous and time-discrete, behavioral and structural models to „mixed-signal macromodels”. Submodels on different levels of Abstraction are combined, too (multi-level approach). Due to the complexity of such models, an automatic generation is not possible. Instead, a heuristic approach is proposed and illustrated by some examples from industrial design tasks. In addition, the application of the forthcoming mixed-signal hardware description language VHDL-A is discussed.
