Hi, There is technique called Asymptotic Waveform Evaluation (AWE) which is well known in VLSI. ( my field is electromagnetics.) Before I try to implement any of that in the books or papers, I wonder there is any program I can try out, well-written manual, or simple source code that I can study with. I believ that the AWE technique and its modified version (like Arnoldi or Krylov algorithms) are used by SI engineers to analyze complicated circuits. Any comment will be appreciated. Thanks Sincerely, se-ho You ------------------------------------------------------------------ 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
