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.

We’re seeing an increase in optimism as more people are vaccinated and states under lockdown begin flipping open their shutters. This positive outlook is spreading, albeit slowly.

Rarely do we have the luxury of designing a board just for connectivity. When interconnects are not transparent, we must engineer them to reduce the noise they can generate. This is where design for signal integrity, power integrity and EMC—collectively high-speed digital engineering—are so important. Eric Bogatin offers seven tips for stackup design.
