A method for automatic design of analog circuits based on a behavioral model

A novel method for automatic synthesis of analog circuits is presented. A domain knowledge including circuit theory laws as well as circuit library and heuristics is used. The behavior and topological properties of the desired circuit are first derived. A behavioral graph with respect to the behavior of the basic components is then devised to match the behavior of the desired circuit. The behavioral model is then transformed to a corresponding circuit for an acceptable solution. These operations use algorithmic approaches for behavioral and topological modification based on KVL and KCL laws. Consequently for a given design problem this method is able to produce different circuit topologies which do not necessarily exist in the library.
