Ravinder, One more thing I'd like to mention is the hierarchy in which parasitic = parameters are handled in SQ (see SQ Simulation and Analysis Reference = documentation for detail). There are three levels:=20 1. Estimated pin parasitic data in a device model 2. Individual pin data in a device model 3. Package Model used with a device model When individual pin data is used, item 1 is ignored. When a package model is used, items 1 and 2 are completely ignored. This = means that each pin's parasitic value must be defined in the package = model.

Also thanks to all of you who responded. = After=20 I ran ibis2signoise to translate the .ibs and .pkg models, the .dml = files=20 were generated for both the models, and Device model had a reference to=20 the Package model. Only, it didn't show up as pin parasitic in the pin=20 data. As you indicated in your note, I was able to see the package = model=20 in the subcircuit, when I simulated the net in SigXp.

If you want to double-check, you can run a sim in SigXp, and go look at the spice file it generated in the latest sigxp.run\case#\sim#\comps.spc file. You should see the subcircuit in there.

Later, I translated the .pkg =3D file=3D20 to another .dml file and now I can see the package model in the = model=3D20 library with the same name contained in the buffer .dml file. However, = =3D I=3D20 am not sure if SPECCTRAQuest will use this package model during run =3D time,=3D20 because the .dml file for buffer model still does not show any pin info. = =3D Am I doing something wrong here. I will very much appreciate your help in this matter.=3D20 Regards, Ravinder Server PCB and Flex Development Hitachi Global Storage Technologies Email: Ravinder.Ajmani@xxxxxxxx ------------------------------------------------------------------ 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: =3D //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: =3D20 = //www.freelists.org/archives/si-list or at our remote archives: = http://groups.yahoo.com/group/si-list/messages=3D20 Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu =3D20 ------------------------------------------------------------------ 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:=20 = //www.freelists.org/archives/si-list or at our remote archives: = http://groups.yahoo.com/group/si-list/messages=20 Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu =20 ------------------------------------------------------------------ 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: =20 //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages=20 Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu =20 ------------------------------------------------------------------ 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
