Mentor White Paper: Analyzing Crosstalk’s Impact on BER Performance


Reading time ( words)

This paper by Mentor Graphics’ Vladimir Dmitriev-Zdorov and Zhen Mu discusses two major issues associated with channel crosstalk that have not been fully addressed previously: models from measurements and algorithms for BER prediction.

It presents a practical solution that allows designers to add in near-end or far-end crosstalk characterized by a group of 4-port S-parameters, rather than to perform multiport parameter characterization.

The paper then presents in details two simulation approaches for channel crosstalk: synchronous and asynchronous algorithms, and considers their implementations in time and statistical domains.

Finally, it gives examples of the proposed procedures implemented together with IBIS-AMI buffer models and discusses their comparative advantages and limitations.

The IPC High-Reliability Forum and Microvia Summit covered a broad range of topics related to reliability and provided interactive opportunities to share expert knowledge and experience in determining and understanding the causes of failure and selecting the best design rules, materials, processes, and test methods to maximise product reliability.

Stitching Capacitor: Crosstalk Mitigation for Return Path Discontinuity

06/13/2019 | Chang Fei Yee, Keysight Technologies
When the return path is broken due to the switching of reference planes with different potential, e.g., from ground to power or vice versa after layer transition on PCB, the return current might detour and propagate on a longer path, which causes a rise in loop inductance. This might lead to the sharing of a common return path by different signals that pose a high risk of interference among the signals due to higher mutual inductance. This interference results in signal crosstalk. To mitigate the crosstalk due to return path discontinuity (RPD), stitching capacitors are mounted on the PCB to serve as a bridge between the two reference planes of interest on different PCB layers.

Technically Appropriate Material Choices are Key to Design Success

05/16/2019 | Nolan Johnson, I-Connect007
Materials are no longer a passive part of the design; they play an active role in the manufacturability, reliability, and speed of a PCB. I-Connect007’s Nolan Johnson and Mike Creeden, founder of San Diego PCB Design, discuss several key characteristics that designers should consider in their material selection process.
