Hi Everybody: I need to perform some high speed simulations (over 3GHz) for my backplane and I currently have the Mentor HyperLynx tool. I have run into a little problem. HyperLynx needs IBIS models for simulation purposes, whereas most of the vendors provide only spice models and not IBIS. Although HyperLynx can convert Spice models to IBIS, it does need a Spice simulator to do that. I am a little confused here and am hoping I can have these questions answered. 1. Can I use just Hspice to perform all my high speed simulations or is HyperLynx a better tool for this application? 2. Has anyone had experience with converting 3D spice models to IBIS? What are the tradeoffs? 3. HyperLynx has three levels of licenses - regular, EXT and GHZ. Which one should I be using? Thanks in advance. -Naveen. ------------------------------------------------------------------ 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
