Printed Circuit Design & Fab - February 2008 - (Page 27) MODELING software to create S-parameter data and an accurate model of the channel. PCD&F Ed note: This paper was previously presented at PCB Design Conference East in Durham, NC, October 2007. ACKNOWLEDGEMENTS Many thanks go to Martin Schauer and Antonio Ciccomancini at CST for the valuable feedback provided on the modeling of this channel. We’d also like to acknowledge the assistance of Dana Bergey and Jonathan Buck, with FCI, who provided the test vehicles used in this experiment and the model file for the AirMax connector. FIGURE 10.

Summary We have shown the feasibility of using full-wave electromagnetic modeling to simulate the behavior of a highspeed differential backplane channel. The simulated results match well with empirical data. The measurement technique described consists of taking TDR measurements and using http://www.cst.com http://www.wssi.com/pcdm http://www.wssi.com/pcdm
