Validation of high-speed interface performance in a given design space from a Signal Integrity (SI) perspective requires Bit Error Rate (BER) computation. Eye Height (EH) and Eye Width (EW) are used to determine the quality of an interface for a given set of design parameters and frequency of operation. EH, EW and BER estimation requires Time Domain (TD) simulation of complex channel models over billions...
Proper transmission of high speed signal requires sufficiently high bandwidth of the medium. The reference planes play a vital role in achieving distortion-free signal propagation. In this paper a BGA package design exhibiting resonance conditions in insertion loss is analyzed. Analysis led to ground path issues caused by return current density congestions. Improvement in ground return path layout...
This paper proposes an accurate and effective modeling approach by incorporating a de-embedding method when de-composing electrically large PCB/Package models into smaller sub-models. The proposed technique allows to accurately taking into account the discontinuities at the PCB/package interface while reducing the simulation effort.
A novel wideband filter is designed for common mode noise (CMN) suppression in high-speed differential signaling. The dumbbell-shaped defected ground structure (DGS) is periodically etched in the return path of differential line to suppress CMN. In order to improve the signal quality of the differential transmission, a periodic stub-loaded structure is designed to compensate the discontinuity of the...
