Hassan, I have done some of this correlation myself between HSPICE and Ansoft, as well as with a couple of other pieces of software. Some of the work was completed in collaboration with UMR. From version 2001.02 up to the most recent update of HSPICE gives pretty good correlation. Earlier versions of HSPICE showed a slightly greater variance in the L and C values. The simulations were run up to 10GHz. Regards, Craig -----Original Message----- From: Hassan O.

Hi All, Has anybody checked the accuracy of differential RLGC parameters computed by HSPICE's internal field solver against those computed by other full-wave field solvers such as Ansoft Maxwell 2D Extractor, HFSS, etc, over a broad frequency band? Thanks. Hassan. ------------------------------------------------------------------ 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 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 ------------------------------------------------------------------ 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 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
