I believe there is a method in XTK for simulating these kind of MOS switches with actual device models. I don't know if the IBIS data has what you need for this, however. -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx]On Behalf Of Aspnes, Brian D Sent: Wednesday, March 05, 2003 11:44 AM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] Modeling a MUX/DEMUX? If you wanted to model the IDT MUX parts IDTQS3VH257 and IDTQS3VH253 = for pre-layout simulations, in a series net configuration [such that the MUX/DEMUX is in series with your trace ("Y" to "In", with select and = enable "on")], how would you model the MUXs with a Single Line Lumped Model = "SLM" type environment (we use Innoveda Scratchpad/ePlanner which uses .ibs = models and "schematic" versions of connectors/bus switches). =A0 Driver -> Trace -> MUX/DEMUX -> Trace -> Receiver=20 =A0 Does anyone have a Single Line Lumped Model (SLM with one input, one = output) that I can use for signal integrity analysis similar to this connector = model from AMP (Mictor): = http://www.amp.com/simulation/scripts/models.asp#list=20 =A0 Brian Aspnes Intel Communications Group (ICG) E-mail: brian.d.aspnes@xxxxxxxxx ------------------------------------------------------------------ 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 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 ------------------------------------------------------------------ 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 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
