Chair, IBIS Open Forum -----Original Message----- From: Mirmak, Michael=20 Sent: Wednesday, December 12, 2007 5:26 PM To: si-list@xxxxxxxxxxxxx Subject: Draft Touchstone 2.0 document available The IBIS Open Forum has completed a draft of an improved Touchstone specification, entitled Touchstone 2.0, to expand the capabilities of the original format and eventually release it as an industry standard. Some of the changes in the new version include: - support for independent per-port reference impedances - the number of ports that may be represented is unlimited - support for lower- or upper-half matrix representations, to reduce file size - the version number, the number of ports and the number of frequencies in any file have all been made explicit Backward compatibility with 1.0 models has been preserved. Touchstone 2.0 will be formally introduced at this week's IBIS Open Forum teleconference, for review and comment in preparation for standardization. The latest review draft may be obtained at the URL below. Comments are welcome. http://www.eda.org/ibis/docs/touchstone2_review_draft.pdf=20 - Michael Mirmak Intel Corp.=20 Chair, IBIS Open Forum http://www.eigroup.org/ibis/ http://www.eda.org/ibis/ ------------------------------------------------------------------ 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 technical documents are available at: http://www.si-list.net 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
