Hello All, -Is there any major change in ibis-v4.2 w.r.t. ibis-3.2 ragarding generation of following tables: [POWER Clamp] [GND Clamp] [Pullup] [Pulldown] [Ramp] [*ing Waveform] -My simulation software vendor says that it supports only ibis-v4.2 and higher specs. So, I changed "[IBIS Ver] 3.2" to "[IBIS Ver] 4.2" in the ibis file (supporting ibis ver 3.2) of bidirectional buffer generated by me . And tried to simulate it with the simulation software provided by my vendor. Is it technically incorrect to change only [IBIS Ver] and to keep other tables same , while shifting to higher versions. i.e.,are ibis versions backward-compatible ? Thanks in advance for your feedback, Best Regards, Sudhanshu ------------------------------------------------------------------ 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
