Hi, Experts In 2.5 field solver(eg: Sigrity or SIwave), if i want to get DC resistance of interconnect, i use the two method: 1 Use FEM to calcute from DC to Fmax Hz, use the DC s parameter to get the S parameter 2 Use IR drop in the analysis to get the DC resistance but the two method give two different DC resistance value, Which one i should trust? Thanks. ------------------------------------------------------------------ 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 forum is accessible at: http://tech.groups.yahoo.com/group/si-list List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
