Ray, I heard a paper on StatEye by Sanders, Resso, and D'Ambrosia at DesignCon East last month, and I was intrigued by the idea. In particular, the paper seemed to be making a theoretical connection between bit error rate and eye opening, which I've never seen before. Since I'm pretty new to the serial link world I could use a very high-level explanation of the technique. It seems to depend on replacing the familiar SI phenomena (crosstalk, ISI, PDN noise) with statistical entities and then finding the response of a complete link (transmitter+interconnect+receiver) to the convolution of these individual statistical entities. Did I get this right? Is there someone out there on the OIF that would care to explain the "general idea" in a couple of paragraphs? Thanks in advance.

StatEye uses statistical methods to derive an eye diagram and jitter metrics for a channel characterized by s-parameters. StatEye runs under Matlab 6.5.1 StatEye is a leading standards development tool, used widely by a standards groups working with high speed interfaces. From their web site: "StatEye is a non-profit open source forum for the development and validation of physical interface channels and the signalling technology. Our mission is to proliferate the use of a standard method for the analysis of interface channels, that can be used by system and chip developer alike." The StatEye web site: http://www.stateye.org/ hosts the downloadble code, documentation, papers and presentations and a forum dedicated to StatEye topics. -Ray Anderson Sun Microsystems Inc. ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
