Efficient generation of analog circuit models for accelerated mixed-signal simulation

Transient analysis of mixed-signal circuits suffers from drawbacks inflicted by the high computational effort required for the simulation of analog blocks. We propose to generate linearized state-space models describing the analog circuit behavior, avoiding any numerical integration during simulation. Since only a small fraction of all possible linearized model regions is used in common circuits, an efficient on-the-fly computation is possible. Interfacing such models to a SystemC digital simulator allows for an accelerated mixed-signal system simulation outperforming traditional concepts by at least one order of magnitude.
