Abstract: Transient analysis is an important circuit simulation technique. The circuit
model, which is a system of differential-algebraic equations, is solved for a given initial
condition using numerical time integration techniques. Multirate methods are efficient if
the dynamical behaviour of the circuit model is not uniform. This paper deals with the
analysis and control of the discretization errors for multirate time integration methods.
