Chris, That same little bird reminded me to a discussion I had with one of the=20 engineers of the company who's simulator was used in that project you are referring to. That engineer was quite familiar with the tool's algorithms and architecture, and told me that part of the problem with the performance of those models was that the tool was not architected for such tasks, and with some architectural changes it would have been able to run much faster... I agree, modeling the receivers may not be an easy task, but it is probably not impossible either. And as we learn more about behavioral modeling we may find better ways of doing things which we would have never thought of before. (As they say, practice makes master).

A little bird reminded me that a few moon's ago some not so smart individual worked with some very smart vendors to tackle the behavioral receiver problem on a very specific but relatively simple receiver. From that experience one can clear see the limitation of behavioral models when it comes to representing receiver performance. And how fast did those behavioral receiver models run again ? ;-D That was many moons ago (what took the rest of you so along btw) and the complexity of receiver designs have exponentially grown since then. =20 But then again, I am just a dumb, stubborn and die hard SPICE kinda guy. One step ahead, that's all I need..... ------------------------------------------------------------------ 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: http://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: http://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
