Interestingly, Saber supports VHDL-AMS. Check it out: www.vhdlams.com Unfortunately, it lacks the field solvers and PCB interfaces that are required for an effective SI tool. =20 -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On Behalf Of Geoff Stokes Sent: Thursday, March 24, 2005 3:28 AM To: 'Chris.Cheng@xxxxxxxxxxxx'; si-list@xxxxxxxxxxxxx Subject: [SI-LIST] Re: package SSN model accuracy requirements I am surprised no-one in this thread has mentioned Saber (previously Analogy, now Synopsis) which has its own modelling language, not too difficult to learn, conforms to Kirchoff, and has a library of generalised models. Some years ago I implemented an experimental model for a GaAs MESFET in Saber. Significantly, Saber has not been heavily marketed in recent years - perhaps someone from Synopsis can tell us why?
