The co-existence of two different sets of parameter definitions, requirements and specifications in the domain of digital system design; namely the time domain (TD) and frequency domain (FD), is imposing some challenges on digital system design. Those challenges are increasing with the increase in system speed and are hard to address using traditional methods. This paper proposes a new methodology...
Aim of this paper is the signal integrity analysis of multilayer boards with emphasis on the effect of non-functional pads. In particular it is demonstrated how removing the nonfunctional pads to reduce the coupling mechanisms of the pads with the planes above and/or below can not be considered a general rule of thumb due to possible larger impedance variation (TDR). Accurate and reliable numerical...
Object of this paper is the signal integrity analysis of printed circuit boards with electromagnetic bandgap structures. In particular the signal quality of single-ended and DIFF lines is discussed both in time and frequency domain (S-parameters, TDR and eye-diagrams). Two different configurations (two dimensional and three dimensional) of electromagnetic bandgap structures are analyzed by means of...
A simple rule of thumb is proposed for automatic model order estimation of the rational macromodels for passive components and systems. Based on an analysis of the dynamic behavior of the (measured or simulated) frequency domain scattering parameters, upper and lower bounds for the number of poles are proposed. Several interconnection examples with different complexity are presented to illustrate...
