Hi Bob, The way I've done it is to get the single ended S-parameters and use = MatLab to post-process the single ended data to get the mixed mode = S-parameters. Essentially, have matlab do the linear transform. There may be ways to setup the sources to get just the quadrant you're = interested in directly, but you always loose all the other information, = i.e. the cross mode coupling and the even mode. Hope this helps, Bill > -----Original Message----- > From: Bob Patel [mailto:whizplayer@xxxxxxxxx] > Sent: Thursday, February 13, 2003 4:28 PM > To: si_list > Subject: [SI-LIST] S-parameter for differential signals in Hspice >=20 >=20 >=20 > Hi!
