dear Saoer, the answer to your question depends on 1) what effects you need to model 2) what simulation resources you have to use the model 3) what is the accuracy you need to achieve may be you may want to better specify your needs. Regards Giancarlo -----Messaggio originale----- Da: si-list-bounce@xxxxxxxxxxxxx per conto di Saoer Sinaga Inviato: mer 29/11/2006 10.25 A: si-list@xxxxxxxxxxxxx Oggetto: [SI-LIST] digital core model Hi all, I want to do System in Package modeling. The SiP is laminate based, and consists of several active silicon dies. What kind of model should I use for those active dies? Should I use transistor-level model? or should I use the current profile information? or just a simple norton equivalent core model? Anyone could give me an idea? or perhaps refer some papers or books? thanks a lot, Saoer ------------------------------------------------------------------ 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 ------------------------------------------------------------------ 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
