Object-oriented knowledge-based framework for open modeling in hierarchical simulation of microsystems

We present the features of the hierarchical approach for (micro)system simulation, emphasizing specification formalisms. Our first contribution is directed toward object-oriented translation of Bondgraph Language to Analog Hardware Description Language; beside its practical importance, we regard this as a way of developing an Object-Oriented Analog HDL. Then, we combine the advantages of object-orientation and constraint propagation in approaching and managing hierarchically analog designs. Therefore, we build an object-oriented knowledge-based simulation framework, open to user-defined models, as well as to integration of new simulation operators, trying to represent hierarchical design and verification strategies.
