Semi-symbolic simulation is becoming popular for inclusion of parameter uncertainties in the system design analysis. For robust control system design optimization, computational methods enabling fast semi-symbolic simulations are necessary. We propose an operational computation method based on orthogonal signals that is faster than step integration methods and allows the direct evaluation of system...
We present a general mathematical model of signals for efficient and accurate simulation of analog and mixed signal (AMS) systems. It relies on signal coding and parameterization and allows heterogeneous system specification at different abstraction levels, as well as, the operational computation of continuous time systems' dynamical behavior. In particular, we derive a matrix for operational subdivision...
Ideal instantaneous switches are a useful behavior abstraction technique to model semiconductor components in power system development. It allows fast and robust simulations of sophisticated power controls. In this paper we present a SystemC AMS extension to support modeling and simulation of externally as well as internally controlled electrical linear networks with ideal switches. By using this...
