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.

It’s showtime! This past week, we saw quite a bit of news about virtual trade shows. It’s great to see show managers pivot from live, in-person events to virtual shows with only a few months to make it all happen. How would you like to be a show manager today?
