A method for simulating analog behavior of a circuit in a simulation system includes representing the circuit as a hierarchically arranged set of branches, which includes a root branch and a plurality of other branches logically organized in a graph. The hierarchically arranged set of branches includes...http://www.google.de/patents/US20050143966?utm_source=gb-gplus-sharePatent US20050143966 - Systems and methods for efficiently simulating analog behavior of designs having hierarchical structure
