Original Abstract

The paper deals with behavioral modeling of switched systems with discontinuities. The purpose of such models is to obtain the first-order effects to verify analytic calculations or to increase simulation speed. Traditional algorithms for the time-domain analysis implemented in Spice-class simulators are based on the assumption of smoothness and continuity. Abrupt changes of system parameters or even discontinuity during switching cause numerical errors. The VHDL-AMS language brings radically different approach in comparison with Spice [1]. The system of differential algebraic equations can be formulated explicitly and can be structurally modified during simulation. The basic principles will be demonstrated on the model of boost converter with accelerated finding of steady-state solution.
