Abstract :
In this paper, a novel adaptive stopping criterion for FDTD simulations of microwave components is applied to a package example. The new stopping criterion relies on the Vector Fitting algorithm to successively build an updated macromodel for the frequency response of the device under study based on increasing time-limited transient responses. In this way, it aims at minimizing the number of timesteps and, hence, the overall simulation time to capture the device´s frequency response within a given frequency band up to a predefined accuracy level.
