A synchronization algorithm for VHDL-AMS simulation with ADA feedback effect

The nature of analog and digital simulation is different, so they work with two different simulation kernels. Synchronization between these two kernels is an important challenge in the mixed signal simulation subject. In this paper we introduce an algorithm for mixed signal simulation that works based on reducing the analog and digital simulation interaction. When the simulator switches to analog simulation, the analog solver initiates the analog parameters to start analog simulation. Resuming the analog simulation needs some additional steps; we reduce some switching between analog and digital simulation. The efficiency of the new algorithm is shown by some examples.
