Abstract:
Methods, systems, and computer readable media are disclosed for simulating a circuit. The method may comprise a step of providing a network model of the circuit having a plurality of ports, the plurality of ports being associated with one or more net pairs. The method may also comprise combining the plurality of ports into one or more groups based on the net pairs, each group corresponding to a net pair. In addition, the method may comprise calculating, for each group, one or more expansion elements, wherein the one or more expansion elements are associated with a shared property among all ports of the group. Moreover, the method may comprise simulating the circuit using a combination of the expansion elements calculated for each group.
