SystemC mixed-signal and mixed-level simulation using an accelerated analog simulation approach

Abstract

When simulating mixed-signal systems, designers are often dissatisfied either with performance or accuracy. A state-space based precomputation method for analog circuits at electrical level allows for a considerably faster simulation than with SPICE-like simulators. Utilizing an automatically generated SystemC interface, our simulation kernel analyzes mixed analog/digital circuits where the digital components are described on a higher level of abstraction than the analog parts. Results show a speedup of up to two orders of magnitude compared to mixed-signal simulation using ModelSim coupled with Saber or HSpice.
