Abstract
Improved performance of simulation analysis of a circuit with some non-linear elements and a relatively large network of linear elements may be achieved by systems and methods that partition the circuit so that simulation may be performed on a non-linear part of the circuit in pseudo-isolation of a linear part of the circuit. The non-linear part may include one or more transistors of the circuit and the linear part may comprise an RC network of the circuit. By separating the linear part from the simulation on the non-linear part, the size of a matrix for simulation on the non-linear part may be reduced. Also, a number of factorizations of a matrix for simulation on the linear part may be reduced. Thus, such systems and methods may be used, for example, to determine current in circuits including relatively large RC networks, which may otherwise be computationally prohibitive using standard simulation techniques.
