["Zanella, Fabrizio" <fzanella@xxxxxxxxxxxxx>]

Very good paper, Mark and Howard. I was not able to attend the webinar.
Can you discuss what process you used for the simulations of the package
crosstalk?  Were they spice simulations using multiple coupled line
package models?
Thanks,=20

Subject: [SI-LIST] Paper on BGA crosstalk and power system

Hey all,
Some of you may have already attended this, but I wanted to draw your=20
attention to a WebCast seminar and accompanying paper that was released=20
yesterday.  The topic is a joint study by Xilinx and SigCon (Howard=20
Johnson) of crosstalk and power system noise in FPGA systems.

The paper:
http://www.xilinx.com/products/virtex4/pdfs/BGA_Crosstalk.pdf

The archived WebCast (might not be available until tomorrow):
http://www.xilinx.com/events/webcasts/tol/01feb05.htm#3

The WebCast is a full hour with Q&A at the end; the paper /seems /long=20
but is actually pretty easy to read.  I especially like Howard's=20
explanation of the crosstalk model of power system noise and why it's=20
appropriate to the large BGA scenario.

I'd be very interested to hear feedback from people on the list --=20
factors we didn't consider, overall usefulness of the information=20
presented, ideas for future studies on the same measurement platform.=20

Thanks!
mark
