Multirate ROW methods and latency of electric circuits (Q1308562)

Large nonlinear systems of ordinary differential equations obtained by the nodal analysis of highly integrated electric circuits are investigated. Multirate Rosenbrock-Wanner schemes with micro and macro- steps on a fixed discretization level corresponding to the active or passive components of the electric circuits are proposed. Consistency conditions and the convergence for a method of order \(p\) are established. As a test example an inverter chain is considered.
